摘    要:研究目的:分析区域生态系统服务价值对于沿海滩涂用地开发的响应。研究方法:敏感性分析法与弹性分析法。研究结果:目前三种主要的滩涂开发利用方式都会引起区域生态系统服务价值的减少,但三者减少的幅度存在差异;将滩涂资源开发成建设用地的ESV敏感性最强,部分区域达到0.93;在滩涂转化为耕地的过程中,ESV敏感性居中(0.50左右);而将滩涂开发成养殖水面的ESV敏感性最小;滩涂开发的ESV敏感性与区域滩涂数量密切相关,滩涂面积越大,滩涂开发的ESV敏感性越强。研究结论:为了保障区域生态安全,促进社会经济与生态环境协调可持续发展,应科学规划滩涂用地布局,保护滩涂生态系统。

关 键 词:生态系统服务价值  滩涂开发  生态服务价值响应  江苏省沿海地区

Abstract:The purpose of this study is to analyze the sensitivity of regional ecosystem service values to tideland development.Methods of sensitivity and elastic analysis were employed.The results show that all of present 3 prevalent modes of tideland development make regional ESV decrease;however,the magnitude of decreases is different.The ESV sensitivity to converting tideland to construction land is the highest,with value of 0.93% in some area,while that of developing tideland to aquiculture use is the lowest,and that of converting tideland to cultivated land is moderate.It shows that the regional ESV sensitivity to development is closely related with scale of developed area,The larger the tideland area is,the higher the ESV sensitivity to development.Conclusion of this study is that,in order to ensure safety of regional ecosystem and to promote coordinated development between ecological and soc-economic aspects,tideland development should be planned legitimately and the tideland ecosystem should be protected properly.
Keywords:ecosystem service values  tideland development  sensitivity  coastal region
