基于RS与GIS的城市近郊土地覆盖/利用时空分异研究——以上海市青浦区为例
Study on the Spati al-temporal Differentiation of Land Cover/Land Use in Suburban Area Based on RS and GIS— Taking Qingpu District,Shangh ai City as an Example
摘要
Abstract
Taking Qingpu District of Shanghai City as study area,based upon the accurate registration of Landsat5 thematic mapper imagery data of the study area,followed with PCA-ISODATA method for the classification of data and post processing and in situ investigation,the land cover/land use maps of specific years were obtained.Based on the relevant information and yearbook,the spatial and temporal distribution characteristics of land use change in Qingpu District and its driving mechanism during 1998-2007 were analyzed by GIS.The study showed as follows:when en-tering the new millennium,the main change was that the built-up expands great area and cohesion,especially in northeast of region;the built-up expansion was driven by distance to city center,moreover the closer to the roads,the easier built-up conversion from other landforms would hap-pen.At the meantime,the agricultural land decreased drastically and woodland enhanced as forest planting or economy of forestry.Lakes and river networks in western region mainly driven by history,for the aquiculture,the water area was a litter increased.From social economic statistics,sec-ondary and third industries were over 4 fold and non agricultural population doubled illustrates this change in ten years.Urbanization and the mass population gathering towards big city were leading this change pattern.关键词
