基于遥感的临安市土地利用变化及驱动力分析

以浙江省临安市为研究区，利用1991年、1998年和2007年3期遥感获取资料和地形图，对土地利用变化特征、动态度以及各种土地利用类型的转移变化进行探讨分析，并结合自然、社会经济和制度等因素分析了研究区土地利用变化的驱动力。结果表明：临安市土地利用结构变化表现为耕地锐减，建设用地大幅增加，林地小幅减少，水域略增。研究区土地利用程度、动态度以及各土地利用类型的转移程度差异较大。图1表4参11

Land utilization changing and driving force analysis based on remote sensing data in Lin'an

Lin'an City of Zhejiang Province was selected as a case study to help understand change of land utilization pattern, dynamic degree, and transfer matrix of all land utilization types. We studied remote sensing data from 1991, 1998 and 2007 and topographic maps. And by analyzing the natural condition, e-conomy and social system of Lin'an City, we want to get the change driving force of land utilization pattern. The results showed that farmland coverage declined sharply, forest coverage went low too, but building lot coverage increased greatly, and waterbody added a little. There were obvious difference in land utilization degree, dynamic degree, and transfer degree of land utilization types in Lin'an City. Ch, 1 fig. 4 tab. 11ref. ]
