摘要
城乡建设用地是人类活动对自然影响最深刻的区域,当前及今后一段时期是我国新型城镇化、新型农村社区发展的关键阶段,研究区域性城乡建设用地变化规律具有重要意义.本文利用1990年和2013年Landsat TM/ETM卫星遥感影像数据,运用GIS空间分析功能,对聊城市城乡建设用地变化的过程进行了研究.结果表明:1990-2013年,聊城市城乡建设用地增长明显;各类建设用地增长的同时,中心城区与县城建设用地所占比例增加,乡镇、农村居民点用地所占比例减少;聊城市各县(市、区)城乡建设用地均有所增加,但变化强度有明显的区域差异.
Urban‐rural construction land is the area of most profound impact by human activities on natural ,the current and future period is the key stage of the new urbanization and new rural com munity development in China ,so ,it is important of studying the changes of regional urban‐rural construction . In this paper ,utilizing the Landsat TM/ETM satellite remote sensing images of two different periods of years ,1990 and 2013 ,the GIS spatial analysis function ,Liaocheng city urban‐rural construction land changes was studied .The results showed that during the 1990‐2013 ,Liaocheng city urban‐rural con‐struction land increase obviously ;all kinds of construction land are grow th ,at the same time ,the pro‐portion of the central city and tow n construction land increased , the proportion of the villages and towns ,rural residential land proportion reduced;Liaocheng city counties （cities） of urban‐rural con‐struction land increased ,but the changes intensity has obvious regional and spatial difference .
