Abstract

The coastline of Zhejiang is the most intensively developed region in China for industry. Based on GF-1 images, an object-oriented classification for coastline was created to monitor coastline exploitation status. A carrying capacity model was then developed to assess the coastline carrying capacity in Zhejiang by means of coastline carrying capacity index (CCI) which is based on coastline artificial parameters and evaluation criterion. The result indicated that coastlines in Cixi, Zhenhai, Fenghua, and Longwan were overloaded with CCI less than 0. The coastlines in Pinghu, Yinzhou, Ninghai, and Dinghai were critically overloaded with CCI ranging from 0 to 0.20. The other 17 sections with CCI bigger than 0.20 were considered load sections. It can be argued that the overloaded sections and critical overload sections in urban regions should be in primary consideration for protection. This study provided a possible model for coastline management with respect to exploitation and ecological function conservation.

1 Introduction

The coastline is not only the boundary line between the sea and the land, but also the transition zone from terrestrial ecosystem to marine ecosystem. It has biodiversity conservation, marine disaster protection, tourist leisure and entertainment, and other ecosystem service functions [1]. Most of the industry of iron and steel, petrochemical engineering, and mechanical manufacture transfer to coastline with global economic integrating in recent decades. This drives large-scale exploitation of the coastline with sea area reclamation, port construction, aquaculture, and other human activities. The exploitation changed coastline landscape and destroyed ecosystem service function of the coastline [2]. The conception of carrying capacity in ecology comes from population ecology. The earliest carrying capacity is the maximum number of individuals living in a specified condition [3]. Malthus introduced the carrying capacity into human ecology and proposed that the resource and environment restrict the growth of population in the end of eighteenth century. Then, he established the basic framework of carrying capacity research based on the logistics model of population carrying capacity [4]. Park and Burgess gave the definition of carrying capacity from the viewpoint of “capacity” and analyzed the relationship between the carrying capacity and the carrying target in 1921 [5]. Hawden and Palmer transferred the expression of carrying capacity from limited capacity to relative balance capacity based on theory of “balance quantity” and “environmental balance” [6]. The study on the carrying capacity of resource and environment was gradually rising from 1930s; scholars carried a lot of research on land carrying capacity, water resource carrying capacity, tourist carrying capacity, environmental carrying capacity, etc. in agriculture area, typical watershed, wetland, natural reserve and other ecologically fragile areas, and created evaluation methods of net primary productivity estimation, ecological footprint, supply and demand balance, comprehensive index, and system models [79]. The carrying capacity research has gradually developed from conception, theoretical analysis to practical application and provided policy guidance for solving problems such as population expansion, resource shortage, environmental pollution, and ecological destruction [1013].

Marine carrying capacity is the capacity of marine resource and environment carrying human activities in a certain area and period where the structure of regional marine resource is consistent with the need of sustainable development, and the function of marine ecosystem still maintains its steady state [14]. The research on carrying capacity of marine resource and environment has aroused the attention of scholars in recent years. William et al. carried carrying capacity research in the Marshall Islands based on the theory of island animal geography balance [15]. Some scholars discussed the relationship between ecological carrying capacity and sustainable development in island from perspective of social demographic factors [1618]. Jusup and Klanjseek proposed a simulation interaction model between marine biology culture and natural environment in the evaluation of the marine ecological carrying capacity of Cape Bolinao in the Philippines [19]. Cao evaluated resource and environment carrying capacity of Hainan island in 2003–2009 by means of ecological footprint [20]. Some scholars introduced energy analysis into carrying capacity of the uninhabited island [21]. Guan proposed DPSIR theory model to establish evaluating indices system of marine carrying capacity and carried marine carrying capacity evaluation in Jingji marine field [14].

High spatial resolution remote sensing images usually refer to remote sensing images with spatial resolution less than 5.0 m. There have been more than 30 optical commercial high-resolution remote sensing satellites belonging to 13 countries in outer space with rapid development of satellite remote sensing technology since this century. The most representative satellites are IKONOS and QuickBird (USA), SPOT (France), ALOS (Japan), and so on. China began to launch high-resolution series remote sensing satellite (GF series) from April 2013. Seven high-resolution remote sensing satellites are running in outer space at present. The GF series satellite covered from panchromatic, multispectral to hyperspectral band and formed an earth observation system with high spatial, temporal, and spectral resolution. High spatial resolution remote sensing images are able to identify more detailed information of the shape, texture, and spectrum on land surface. It is the most effective tools for land surface environment monitoring [22]. It can help managers to know the actual situation of coastline carrying capacity by monitoring coastline use and evaluating its carrying capacity. Aimed to reveal regional difference of coastline carrying capacity in Zhejiang, this paper employed GF-1 satellite remote sensing images as basic data and established object-oriented method of coastline monitoring technology. Then, coastline carrying capacity index was created from perspective of coastline management and applied in Zhejiang coastline.

2 Study areas and methods

2.1 Study areas

Zhejiang coastline, 2021.47 km in length, lies in east coast of China, south of the Yangtze River estuary. The coastline began at Pinghu connecting Shanghai and end in Cangnan in Wenzhou. The coastline is divided into rock coast, sandy coast, silt coast, and estuarine coast. The exploitation intensity of coastline is increasing with the development of Ningbo, Taizhou, and Wenzhou, which lies alone the cost, companying the natural coastline changed to port, dam, pond, and other artificial coastline. This destroyed ecological function of the coastline. This paper divided the coastline of Zhejiang into 25 sections according to the local administrative division. The distribution of 25 sections of Zhejiang coastline is shown in Fig. 1.

Twenty-five sections of Zhejiang coastline

2.2 Coastline monitoring data and preprocessing

This paper collected 10 remote sensing images of GF-1 satellite, which covered all the coastline of Zhejiang clearly. The parameters of these remote sensing images are listed in Table 1. GF-1 remote sensing image has four multispectral bands of B, G, R, and NIR, and one panchromatic band. The panchromatic band pixel resolution is 2.0 m. Because atmospheric rectification and radiation rectification have been processed in satellite ground receiving station, this paper mainly carried the geometric precision rectification as follows: (1) 25 ground control points are evenly set on each satellite remote sensing image, the ground control points mainly choose the intersection of road and dams, which is convenient for the actual location. (2) The ground control points were found by vehicle GPS and surveyed their geographical coordinates by high-precision beacon. (3) Rectification of satellite remote sensing images was carried out by ERDAS IMAGE10.2 refer to the rectification method in relevant literature [23].

2.3 Object-oriented coastline monitoring method

The coastline is divided into natural coastline and artificial coastline according to the completeness of tidal zone. And the natural coastline consists of rocky coastline, sandy coastline, silt coastline, and estuary coastline while the artificial coastline is made up by port coastline, industry and town coastline, dam coastline, and pond coastline. The classification system of coastline is shown in Table 2.
Table 2

Second classification

Description

Natural coastline

Rocky coastline

Bed of tidal zone is rock, it formed a curve coastline of harbor and cape by sea level rising and long process of marine hydrology.

Sandy coastline

Bed of tidal zone is sand and gravel, the particle size of sand and gravel is 0.063–2 mm, it formed relatively flat coastline by long-term action of waves.

Silt coastline

Bed of tidal zone is silt with particle size 0.01–0.05 mm, it formed open coastline by the long-term interaction of waves and runoff.

Estuary coastline

It is located in estuary and is boundary line of river and marine.

Artificial coastline

Port coastline

It is vertical artificial dikes connecting deep water in port

Industry and town coastline

It is a slope dam connecting industry or town and formed by reclamation.

Dam coastline

It is a dam located above the highest tidal line to prevent waves, storm tide, and other erosion. The near region of the dam is nature landscape, usually.

Pond coastline

It is a simple dam for aquaculture, sea salt, and other human activities.

The traditional classification method of remote sensing images based on pixels is not suitable for high spatial resolution remote sensing images for it embodies more abundant information such as texture, spectrum, geometric, etc. Object-oriented classification method is a new way of information extracting for high spatial resolution remote sensing images, which appeared in recent years [24, 25]. This method divided image into scale segmentation and extracts homogeneity region firstly, then analyzed image feature and extracted classification target. It has obvious advantage compared to the pixel-based classification method for the object-oriented method extracts image information in detail from shape and texture of land surface. The object-oriented method is applied in more and more study on high spatial resolution image extracting now. Arroyo applied object-oriented classification to radar and Quick-Bird images to map land cover and estuary shape in coastal zone of the Mediterranean [26, 27]. Platt applied object-oriented method to classify IKONOS image to evaluate the accuracy of land use/land cover [28, 29]. Cleve and others compared characteristics of pixel classification and object-oriented classification using high-resolution aerial images and found that object-oriented method is more suitable for high-resolution image [30, 31].

This paper employed object-oriented classification to extract coastline from GF-1 satellite remote sensing images. First, the GF-1 images were divided into segmentation in suitable scale. Scale segmentation divided the image into pixel group according to the same spectral characteristics and spatial adjacent relations. It can not only generate classification target, but also classify target in hierarchical structure [32]. Then, the spatial image feature library of the coastline was established according to the image spectral features, shape features, and texture features of different coastline type (Table 3). Third, the sample was defined according to the image feature library. And the classifier was inserted to classify image of scale segmentation. Fourth, the ground verification points were collected to test the accuracy of classification; the accuracy of image classification should be more than 90%. The technique flow chart of object-oriented image classification for coastline is shown in Fig. 2.

2.4 Evaluation of coastline carrying capacity

2.4.1 Coastline artificial index

The coastline artificial index is calculated as follows:
$$ {P}_{\mathrm{A}}=\frac{l_{\mathrm{mB}}\times {q}_{\mathrm{B}}+{l}_{\mathrm{mT}}\times {q}_{\mathrm{T}}+{l}_{\mathrm{mG}}\times {q}_{\mathrm{G}}+{l}_{\mathrm{mH}}\times {q}_{\mathrm{H}}}{l_0} $$
(1)
where PA is coastline artificial index, lo is total length of coastline(including natural coastline), lmB is the length of pond coastline, lmT is the length of dams coastline, lmG is the length of industry and town coastline, lmH is the length of port coastline, and qB, qT, qG, and qH are the weights of above coastline types. They are calculated by statistical analysis from 24 expert opinions and shown in Table 4.

2.4.2 Evaluation criterion

The marine functional zonation is key to sea field conservation and utilization management in China. The marine functional zonation divided sea field into eight first-level marine functional zones and 22 second-level marine functional zones. The first marine functional zones include agriculture and fishery zone, port and shipping zone, industrial and urban zone, mineral and energy zone, tourist leisure and recreation zone, marine protection zone, special utilization zone, and reservations [33]. The marine functional zonation clearly defined the location, target, area, and grade for each zone of eight marine functional zone type. The exploitation intensity factors for each marine functional zone were calculated according to the experts’ opinions (Table 5).

The evaluation criterion for coastline was calculated as follow:
$$ {P}_{\mathrm{C}0}={\sum}_{i=1}^8\frac{w_i{l}_i}{l_i} $$
(2)

where PC0 is the evaluation criterion for coastline, li is the length of coastline connecting marine functional zone i, and wi is the permit exploitation intensity factor of marine functional zone i.

2.4.3 Evaluation of coastline carrying capacity

The carrying capacity of coastline is the space of coastline, and the carrying target is human exploitation activities. So, the coastline artificial index is taken as the carrying target, whereas the permitted exploitation intensity of marine functional zonation is taken as carrying capacity for evaluation criterion. The model of CCI of coastline is established as follow:
$$ \mathrm{CCI}=\frac{P_{\mathrm{co}}-{P}_{\mathrm{A}}}{P_{\mathrm{co}}} $$
(3)

where CCI is the carrying capacity index of coastline, PC0 is the evaluation criterion for coastline, and PA is the coastline artificial index. The CCI is divided into three categories, namely, load (S ≥ 0.20), critical overload (0 ≤ S < 0.20), and overload (S < 0), to express the carrying capacity status.

The carrying capacity grades of the coastline in Zhejiang province

4 Results and discussion

Zhejiang coastal zone is the most developed region in China. The coastline artificialization caused by human activities is highest in regions of aquaculture, reclamation for industry and town, port construction, etc. (1) Aquaculture formed pond coastline. The coast of Zhejiang is the estuary of many rivers such as Qiantangjiang, Oujiang, and Jiaojiang. These rivers take large sediment from upper watershed and silt up in estuarine forming silt coastline. The silt coastline is very wide with shallow water and suitable for aquaculture and agriculture. So, the most pond coastlines focused on silt coast, and its coastline artificialization was highest. (2) Reclamation formed industry and town coastline. Reclamation is the most popular human activities of coastal exploitation in China in recent years, which circled and filled sea areas and changed it for land for industry and town construction. The reclamation not only changed sea to land, it is also changed natural coastline to artificial coastline and destroyed ecological function of coastline. (3) Port construction formed port coastline. The large port construction changed natural coast landscape to artificial erect coastline. This change not only destroyed ecological function of tidal zone but also cut away ecosystem service of land near coastline. The port coastline in Zhejiang is clustered in large port of Ningbo-Zhoushan.

There is a close relationship between human activities and carrying capacity in coastline. Human activities are carrying object of coastline, such as fishing, reclamation, port construction, etc. It is increased with economic development. Carrying capacity refers to natural space of coastline capacity for exploitation. It is limited in specific time and region. When the human activities scale out limited carrying capacity, the coastline is overload. Otherwise, the coastline is loaded. In Zhejiang province, the carrying capacity that the coastline provided shows regional big difference and varies with marine function zonation. And the intensity of human activities increased and varied in 25 sections in the last 50 years. The aim of coastline management is to prevent increased human activities from exceeding the carrying capacity. We hope to control human activities through remote sensing images monitoring and carrying capacity assessment before it was overloaded. Moreover, we can view carrying capacity as goal states and aim to achieve them through active monitoring and management. Generally, the higher coastline artificialization, the bigger carrying capacity index in limited coastline carrying capacity. In the future, we recommend that this model should be applied to the practice of coastline management in China.

The coastline of Zhejiang is the most intensively developed region in China for industry. Based on GF-1 images, an object-oriented classification for coastline was created to monitor coastline exploitation status. A carrying capacity model was then developed to assess the coastline carrying capacity in Zhejiang by means of coastline carrying capacity index (CCI) which is based on coastline artificial parameters and evaluation criterion. The result indicated that coastlines in Cixi, Zhenhai, Fenghua, and Longwan were overloaded with CCI less than 0. The coastlines in Pinghu, Yinzhou, Ninghai, and Dinghai were critically overloaded with CCI ranging from 0 to 0.20. The other 17 sections with CCI bigger than 0.20 were considered load sections. It can be argued that the overloaded sections and critical overload sections in urban regions should be in primary consideration for protection. This study provided a possible model for coastline management with respect to exploitation and ecological function conservation.
