沿海岸线资源综合适宜性评价研究——以宁波市为例

Coastline Resources Evaluation of Coastal Ningbo City

沿海岸线资源综合适宜性评价是协调岸线功能布局、提高岸线资源综合利用效益的重要基础,也是引导沿海地区海陆统筹发展的重要纽带。研究基于资源环境承载力与开发活动空间均衡的视角,考虑生产、生活和生态保护等多方面的功能要求,建立评价指标体系,以空间分析和三维匹配分析为支撑,探索沿海岸线资源综合适宜性评价的方法。实证分析表明:北仑、大榭岛、梅山岛、象山湾口门段和石浦港地区岸线建港条件优越、生态环境约束较小,适宜港口和工业开发;象山湾内部和象山县东南地区岸线景观资源丰富、环境优美,适宜旅游开发;象山湾底部、西沪湾西部及杭州湾大桥西部地区生态服务功能重要、环境容量较小,应当严格保护。通过引导岸线的功能分工与布局协调,可以促进案例区岸线有序和持续利用。

The importance attached to the sustainable development of coastal areas is increasing, and coastline assessments are required to minimize environmental destruction resulting from complexity of the property in coastal areas, and human activities. In order to build a comprehensive evaluation index system, the needs of production （port, industry）, living （tourism and leisure） and ecological protection were considered. Ningbo, with coasts on three sides, lies in the Yangtze River delta and has 1600 kilometers of coastline. So far, coastlines have been used for ports, industry and Tidal Flat Reclamation, and little attention has been given to ecological protection. The positive analysis indicates that the method explored in this paper can be helpful for the comprehensive utilization of coastlines. The assessment also shows that most of the coastline in Beilun, Daxie, Meishan, Shipu Bay and the front part of Xiangshan Bay is suitable for port and industry because of good natural conditions and large environmental capacity. The coastline in the southeast part of Xiangshan county and Xiangshan Bay can play a role in the future by making full use of rich landscape resources and environmental properties. Coastline along the bottom of Xiangshan Bay and western Xihu Bay should be protected strictly because of the important ecological function and small capacity of the environment. Guiding coastline development activities according to suitability can maximize the region＇ s coastline and promote the sustainable utilization of coastline.
