基于RS和GIS的土地利用时空动态变化分析--以重庆永川区为例
Analysis on Spatio-temporal Dynamical Change of Land Use Based on RS and GIS ---------- Taking Yongchuan Chongqing as an example
摘要
Abstract
According to the remote sensing images from 2002 to 2008 in Yongchuan distrcit, Chongqing, based on RS and GIS technology, ArcGIS9.2 platform, this paper expressed the ETM+and TM image data of Landsat 7, Landsat 5 satellites, to get the land use pattern in the area of study period and analyzed the spatial and temporal variation characteristics of land use in the study area during the past 7 years, using the land use types of transfer evolution model type area changes and degree of land use, spatial and temporal land use model, qualitative and quantitative method. Research result showed that:the land use change in this area mainly laid in cultivated land and garden plot. Among them, the reduction of cultivated land area was the largest, the change rate of-1.65%;garden increased the largest area, change rate is 11.18%. Cultivated land due to differences in location and comparative economic benefits transferred constantly to other land use types of cultivated land circulation, the reduced whereabouts was mainly residential and industrial land, which accounted for 1.6%and 3.4%of the total area of all types respectively. Transformation of garden area increase came mainly from other agricultural lands and arable lands. The study area from 2002 to 2005 land use was in adjust period or a period of recession, in 2005 and 2008 land use in development period.关键词
