沿海滩涂生态化开发适宜性评价及其在江苏大丰市的应用

SUITABILITY ASSESSMENT OF COASTAL BEACH FOR ECOLOGICAL EXPLOITATION:A CASE STUDY IN DAFENG,JIANGSU

基于我国沿海滩涂生态化开发的需求,构建了沿海滩涂开发评价指标体系,建立了沿海滩涂生态化开发适宜性评价方法。基于压力—状态—响应模型,选取体现滩涂自然生态特征、滩涂开发环境影响特征、滩涂生态保护特征的指标,形成沿海滩涂生态化开发适宜性评价指标体系;运用德尔菲法确定各评价指标的权重,在评价指标量化与标准化处理的基础上,计算综合评价指数,从而确定滩涂生态化开发的适宜程度。以江苏盐城大丰市沿海滩涂为例,对其进行生态化开发适宜性评价,结果表明,在滩涂开发中生态保护措施有力的前提下适宜开发。

This paper presents a complete suitability assessment indicator system and the method for assessment of coastal beach exploitation urgently needed in the coastal beaches in China.The assessment framework is developed upon the basis of pressure-state-response model consisting of the indicators of natural and ecological resources occurred with coastal beaches,environmental impacts and ecological protection.Then the weight of each indicator is defined using the Delphi method and the general index,or the suitability,is calculated after the data processing.The coastal beach of Dafeng in Yancheng,Jiangsu province is selected as a case.The results indicate that the ecological exploitation of coastal beach in Dafeng is moderate in terms of suitability if the ecological protection is effective.
