选取浙江温州苍南县玉苍山风景区作为研究对象,根据玉苍山风景区的特征,选取高程、坡度、坡向、河流、湖泊、植被类型、自然景源、人文景源、景源密度、道路交通、土地利用类型等11个指标因子,利用层次分析法得出各评价因子的权重,再进行加权叠加得出生态敏感性综合评价分析图,从而对玉苍山风景区生态敏感性进行评价。结果表明:该研究区极敏感区、高敏感区、中度敏感区、轻度敏感区、不敏感区的面积分别为2.39,5.20,9.00,13.94,14.70km^2;中度及以上敏感区总面积为16.59km 2,占研究区域总面积的36.68%。研究结果可对玉苍山风景区生态功能区划提供参考。

This study selected,Yucang mountain scenic area in Cangna county,Zhejiang as the research object,according to the characteristics of Yucang mountain scenic spot,11 index factors including elevation,slope,slope direction,river,lake,vegetation type,natural landscape type,human landscape type,landscape density,road traffic and land use type were selected,using the analytic hierarchy process(AHP)to obtain the weight of each evaluation factor,then weighted and superimposed to get the comprehensive evaluation and analysis chart of ecological sensitivity,so as to evaluate the ecological sensitivity o...
