基于GIS的吴江东部地区生态敏感性分析

区域可持续发展的基础是生态环境的可持续,而生态敏感性区划是制定生态环境规划的前提和基础。文章借助GIS技术,选择有区域代表性的生态因子,采用因子叠加法,对吴江东部地区的生态敏感性进行了深入分析,按生态敏感度的高低将研究区划分为5 级:极高敏感区、高敏感区、中敏感区、低敏感区和非敏感区,并提出了分区保护与建设的建议,为研究区生态环境保护和产业经济布局提供有价值的参考。研究结果表明,极高和高生态敏感区面积占研究区的48.63%,说明研究区生态敏感性总体上很高。

GIS-based Ecological Sensitivity Analysis in the East of Wujiang City

The sustainable development of ecology and environment is the base of regional sustainable development,while the classification of ecological sensitivity is the base and premise of the planning on ecology and environment.In this article,with the advanced GIS technology,using the factor-overlay method,ecological sensitivity in the east of Wujiang,Jiangsu Province is thoroughly analyzed by selecting regionally representative factors.Five classes of ecological sensitivity ranging from low to extreme were generated: non-sensitivity zone,low sensitivity zone,moderate sensitivity zone,high sensitivity zone and extreme sensitivity zone,and advices and countermeasures for different zones are put forward,in order to provide valuable references for the environment protection and industry distribution.The results showed that: about 48.63% of the study area was upper moderate ecological sensitivity zone,which shows that the sensitivity is super high.
