GIS支持下旅游小镇生态敏感性评价——以福建省湖坑镇为例

Ecological Sensitivity Evaluation of Tourism Town Based on GIS: A Case Study of Hukeng Town in Fujian Province

文章选取高程、坡度、坡向、水系、土地利用、道路交通、景源和植被归一化指数(NDVI)作为评价指标构建湖坑镇生态敏感性评价体系,利用层次分析法(AHP)确定各权重,通过加权叠加方法得出湖坑镇生态敏感性综合评价图,结果表明,湖坑镇生态敏感性总体水平较高,研究区高敏感区、中敏感区、低敏感区和非敏感区的面积分别为2331.47 hm^2,4671.55 hm^2,2240.64 hm^2,406.21 hm^2,分别占总面积的24.16%,48.41%,23.22%,4.21%。

The development of tourism towns has become an important innovation for the implementation of the rural revitalization strategy.The ecological sensitivity assessment can provide a reference for the sustainable development of tourism towns.The paper selects the elevation,slope,aspect,water system,land use,road,view spots and NDVI as evaluation indicators to develop an ecological sensitivity evaluation system for Hukeng Town in Fujian Province.The analytic hierarchy process(AHP)is used to determine the weight,and the comprehensive ecological sensitivity of Hukeng Town is evaluated using the weighted-overlap method.The results show that the overall level of ecological sensitivity of Hukeng Town is relatively high,while the areas of highly sensitive area,mid-sensitive area,low sensitive area and insensitive area are 2331.47 hm^2,4671.55hm^2,2204.64hm^2 and 406.21 hm^2,accounting for 24.16%,48.41%,23.22% and 4.21%of the total area respectively.
