基于遥感影像土地利用动态变化及驱动力研究——以龙泉驿区为例

On Dynamic Changes of Land Use and Its Driving Force with Remote Sensing Image——A Case Study of Longquanyi District

以成都市龙泉驿区为研究对象,运用RS对龙泉驿区2007年和2013年两个时期遥感影像进行监督分类,将研究区域划分为六种土地利用类型:居民点用地、林地、耕地、水体、道路用地和其他用地,综合GIS技术和马尔科夫模型来研究土地利用动态变化情况.研究结果表明:6年间龙泉驿区的土地利用类型结构有较大的变化,其中居民点用地、道路用地、水体和其他用地呈增加趋势,而耕地和林地则大幅减少.最后,分析探讨影响龙泉驿区土地利用类型变化的因素主要有人口、经济、城市化.

This article,taking Longquanyi District of Chengdu as the study case,applying the RS,classifies the RS images acquired in 2007 and 2013. The study area is divided into six major types of land use：residential land,forest,farmland,water,roads and other land,integrated with GIS and the Markov model to study the dy-namic changes of land use. The results showed that：there are great changes of land use during the past 6 years in Longquanyi District,including residential land,roads,water and the other land increased,while the farmland and forest land are sharply reduced. Finally,the influential factors over the changes of land use in this area,in-cluding population,economy,and urbanization,are also explored.
