云南大围山国家级自然保护区生态敏感性评价及保护对策分析研究

Ecological Sensitivity Evaluation and Protection Countermeasures of Daweishan National Nature Reserve in Yunnan Province

生态敏感性评价为制定研究区域的生态环境综合整治政策提供科学依据。以云南大围山国家级自然保护区为研究区域,选取高程、坡度、坡向、水域缓冲区、道路缓冲区、植被覆盖度、土地利用类型7个生态敏感因子作为评价机制,通过层次分析法(AHP)确定各评价因子权重,运用ArcGIS加权叠加法进行生态敏感性评价,分析结果显示:云南大围山国家级自然保护区的总体敏感程度较高,极度敏感区、高度敏感区、中度敏感区、轻度敏感区、不敏感区面积分别占保护区总面积的5%、8%、10%、27%、50%。本研究可为保护区开展针对性保护与功能区划提供一定的参考依据。

Ecological sensitivity assessment provides a scientific basis for formulating comprehensive ecological environment improvement policies in the study area.Taking Daweishan national nature reserve in Y unnan province as the study area,seven ecological sensitive factors such as elevation,slope,slope aspect,water buffer,road buffer,vegetation coverage and land use type are selected as the evaluation mechanism,the weight of each evaluation factor is determined by Analytic hierarchy process(AHP),and the ecological sensitivity is evaluated by ArcGIS weighted superposition method.The results show that the overall sensitivity of Daweishan National Nature Reserve in Y unnan province is high.The areas of extremely sensitive,highly sensitive,moderately sensitive,mildly sensitive and insensitive areas account for 5%,8%,10%,27%and 50%of the total area of the reserve,respectively.This study can provide a certain reference basis for targeted protection and functional zoning of the reserve.
