随着社会的发展,人们越来越重视生态与环境问题,生态功能区的研究取得了显著的进展,生态环境敏感性的研究也随之进步。通过选取生态敏感性因子,并采用层次分析法进行赋值,利用GIS等软件对宣州区的生态环境敏感性进行研究评价,把生态敏感性分为高度敏感、中度敏感、轻度敏感、不敏感四个敏感类型。根据研究,宣州区的生态环境敏感性大体上由南向北递减,跟地势的高低具有密切的联系,植被类型及降雨等其他因素也对生态敏感性造成不同程度的影响。
Abstract：With the development of society,people pay more and more attention to the ecological and environmental problems,.Ecological functional areas of the research has made significant progress,and the ecological environmental sensitivity studies also makes progress.This article through the selection of ecological sensitivity factor and using of AHP for the assignment and GIS software such as the ecological environmental sensitivity to xuanzhou study,divided into highly sensitive,moderate sensitivity sensitive,mild sensitive,and not sensitive sensitive.According to the study,the ecological environment of Xuanzhou sensitivity decreasing from south to north in general,geting close to the terrain.Vegetation types and other factors such as rainfall of ecological sensitivity also caused different influence.
