基于敏感因子的界首市泉河用地评价

Land Evaluation of Quan River in Jieshou City Based on Sensitive Factors

基于"绿色发展"理念,以2014年界首泉河及周边5个乡镇的遥感影像及统计资料为基础数据,确定流域用地敏感因子,利用RS技术和GIS技术,对研究区土地利用信息进行敏感性分析,对界首市泉河区域的土地敏感性进行评价。结果表明,研究区内大部分区域属于中敏感区,面积占62.6%,高敏感区与低敏感区各占6.7%和18.4%,不敏感区面积占12.3%。

Based on the development of＂green＂concept,the article used the remote sensing image in 2014 and statistical data of Quan River and 5 villages,to determine land use sensitive factors,and using RS technology and GIS technology,the sensitivity analysis of the information of land use and sensitivity evaluation to Quan River of Jieshou City were conducted.The results showed that most of the areas belong to the mid-sensitive and accounted for 62.6%,high ensitive and low sensitive areas accounted for 6.7% and 18.4%,respectively,insensitive area accounts for 12.3%.
