摘　　要：随着国家新型城镇化的快速发展,城镇用地资源矛盾突出,出现了土地资源短缺、环境污染加剧、生态资源不合理开发等一系列环境问题,严重影响了城镇建设的可持续发展。本研究以苍南县马站镇为研究对象,以GIS为技术支撑,结合熵值法和层次分析法确定不同因子权重,对研究区进行单因子生态敏感性评价,然后对单因子加权叠加进行马站镇生态敏感性综合评价。研究表明,马站镇高度敏感区、中度敏感区、低度敏感区和非敏感区面积分别为0.09 hm^(2)、40.48hm^(2)、25.12 hm^(2)和0.45 hm^(2),研究结果可为城镇健康发展提供科学依据。With the rapid development of new-type urbanization in China, the contradiction of land use and resources in cities and towns has become prominent. A series of environmental problems, such as shortage of land resources, aggravation of environmental pollution and irrational development of ecological resources, have seriously affected the sustainable development of urban construction. This paper took Mazhan Town of Cangnan County as the research object,took GIS as the technical support, combined with entropy method and hierarchy analysis to determine the weight of different factors,and carried out a single-factor ecological sensitivity evaluation on the study area, and then carried out a comprehensive evaluation on the ecological sensitivity of Mazhan Town by weighted superposition of single factors. The study shows that the areas of highly sensitive,moderately sensitive, low-sensitive and non-sensitive areas in Mazhan town are 0.09hm^(2), 40.48hm^(2), 25.12hm^(2) and 0.45hm^(2)respectively. The research results can provide scientific basis for urban healthy development.
