摘　　要：以河南省开封市为例,利用2014年与2016年两期GF-1遥感影像数据,解译得到开封市区两年的土地利用类型图。通过GIS软件的空间分析功能得到开封市区两年间土地利用的时空演变特征。基于层次分析法(AHP)对影响城区土地利用类型变化的地域、政策、经济等主要因素进行重要性分析,结果表明:政策和地理因素对开封市区土地利用类型的变化影响最大,开封市西部地区的土地利用变化最频繁。Taking Kaifeng City of Henan province types by using two GF-1 remote sensing image characteristics of land use of the two years by the as an example, this paper obtains this maps of land use data of 2014 and 2016, and its spatiotemporal change spatial analysis function of GIS technology. Based on the Analytic Hierarchy Process （AHP）, and the analysis on the importance of main factors, such as its region, policy and economy, it turns out that the policy and geographical factors have the greatest impact on the change of land use types in Kaifeng urban area. And the change of land use types in its west region is most frequent. Through the research of this paper, it hopes to provide a reference for the related functional departments in the management of land use types.
