基于生态适宜性评价的皖北县域生态功能区划研究——以颍上县为例

Ecological Function Division Study of Northern Anhui Province Based on Ecological Suitability Evaluation——With Yingshang County as an example

以皖北颍上县县域为研究范围,基于研究区域现状发展情况选取评价因子,构建生态适宜性评价指标体系,运用层次分析法量化各评价因子权重,构建评价模型;利用地理信息系统空间分析技术,对各个因子进行空间分析后叠加处理,得出颍上县县域生态适宜性分区;进而从统筹城乡建设与生态环境的角度,划定县域生态功能分区,为研究区域生态控制线划定提供了技术支撑,为其他类似地区生态控制线划定提供参考。

In this study, taking the territory of Yingshang County in northern Anhui as the research area and based on the current development situation of the research area, the evaluation factors are selected, and the ecological suitability evaluation index system is constructed,The weight of each evaluation factor is quantified on the basis of the analytic hierarchy process, and the evaluation model is constructed; With the spatial analysis technique of geographic information system, the spatial analysis of each factor is carried out, and the ecological suitability of Yingshang County is obtained;From the perspective of urban and rural construction and ecological environment, the ecological function of the county district is delineated, to provide the technology support for the study of regional ecological control line, and to provide the reference for the delineation of ecological control line in other similar areas.
