神农架国家公园生态敏感性综合评价

Integrated assessment on ecological sensitivity for Shennongjia National Park

对神农架国家公园生态敏感性进行研究,使国家公园范围内生物多样性保护、科普教育、生态旅游设施布局和社区经济发展更为科学合理.通过建立神农架国家公园生态敏感性评价因子指标体系,采用层次分析法(AHP)确定评价因子权重,构建神农架国家公园生态敏感性综合评价模型,确定神农架国家公园生态敏感度空间分布特点,进而建立神农架国家公园保护区划.结果表明,依据ArcGIS空间叠加影响因子权重综合分析将生态敏感性等级分为极高、高、中等、一般、较低5个等级,各等级区域占全区总面积分别为25.75%、22.42%、43.85%、3.27%、4.71%,依据生态敏感性高低将神农架国家公园功能区划分为4个保护区域,并提出保护措施建议.

The research on ecological sensitivity for Shennongjia National Park makes it more scientific and rational for biodiversity protection,popular science education,ecotourism facilities layout and community economic development within the park. Through establishing assessment factors index system of ecological sensitivity for Shennongjia National Park,utilizing analytic hierarchy process method（ AHP） to determine the weighted coefficients of assessment factors,and then building ecological sensitivity assessment model,which could determined the spatial distribution of ecological sensitivity for Shennongjia National Park and established regional environmental policy mechanism for the purpose of land space protection and development. The research indicates that the ecological sensitivity ranks are extremely high,high,medium,general and low respecttively,which are based on the integrated analysis of the influence factors weight by spatial overlay of Arc GIS,the proportion of each level region is respectively 25. 75%,22. 42%,43. 85%,3. 27%,4. 71%accouting for total area. On the basis of ecological sensitivity,Shennongjia National Park function region is divided into four protection areas,and then puts forward protection measures.
