The Research on Assessment System of Coastal Wetland based on Its Ecological Vulnerability in Yancheng Jiangsu Province

生态环境的脆弱性分析及评估是制定可持续发展的区域发展规划的重要前提,随着人口的增加以及经济的发展,盐城海岸湿地生态系统环境压力不断增强.在分析其海岸湿地生态特性及空间结构的基础上,以生态系统脆弱性为理论指导,以江苏盐城海岸湿地生态系统为研究对象,从生态敏感、生态弹性、生态压力等方面构建了以海岸湿地生态系统脆弱性评价指标体系.旨在为盐城海岸湿地的生态保护、资源利用和可持续发展提供决策参考.

The assessment of ecological vulnerability is an important prerequisite for constituting the regional development planning of sustainable development. The environmental pressures of coastal wetland ecosystems are growing in Yancheng with the population increasing and economy developing.
