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.
To study the ecological sensitivity of Shennongjia National Park, it is more scientific and reasonable to protect the biological diversity, popular science education, eco-tourism facilities layout and community economic development within the national park.By establishing the indicator system of eco-sensitivity evaluation index of Shennongjia National Park, Analytic Hierarchy Process (AHP) to determine the weight of evaluation factor, to build a comprehensive evaluation model of ecological sensitivity of Shennongjia National Park, to determine the spatial distribution characteristics of ecological sensitivity of Shennongjia National Park, and then to establish the Shennongjia National Park protection zoning.Results show that according to ArcGIS spatial superposition impact factor The comprehensive analysis of the weights divides the ecological sensitivity into five levels of high, high, medium, general and low. The total area of each level is 25.75%, 22.42%, 43.85%, 3.27%, 4.71% According to the level of ecological sensitivity, the functional zone of Shennongjia National Park is divided into four protection zones, and suggestions of protection measures are put forward.
