基于RS与GIS重庆都市区土地利用/覆盖变化过程及预测分析
The Process and Prediction of Land Use/Cover Changes Based on RS and GIS in Metropolitan Area of Chongqing City
摘要
Abstract
With the support of GIS and RS technology and the research methods of the dynamic degree of the land use/cover changes,transfer matrix and the Markov process,this paper studies the TM data of two periods（1997 and 2006） from urban Chongqing and predicts the analysis and evolution situation of dynamic process of the land use/cover changes of urban Chongqing in future.And this study provides not only basis of land planning,management and decision,but a source of reference for sustainable development of land resources in this area.The research results reveal that the type of land use of urban district is mainly arable and forest land from 1997 to 2006,the sum of which is more than 70%.The maximum number of transferred land is arable which decrease 506.67 km2.Then with the use of Markov process,land use is inspected and predicted.From 2006 to 2024,the predicted results show that arable area decreases from 62.24% in 2006 to 52.46% in 2024,while construction land area increases from 8.99% in 2006 to 15.91% in 2024.Differently,the area change of forest,grass and water is relatively little.关键词
