Abstract

Based on Landsat TM/ETM image data in the Grand Canal between Cangzhou and Tianjin in 1987,1993 and 2000,the quantitative changes and spatial change characteristics of land use in these regions were analyzed by using RS and GIS information acquisition technology,spatial analysis technique and mathematical statistic method.The main types and directions of land use changes were confirmed.The social and economic development reasons of land use changes were preliminarily discussed.The results showed that the major land covers along the Grand Canal were cropland and woodlands.From 1987 to 2000,the forest and cropland decreased,but the construction land greatly increased.The conversions between forest and cropland and the conversions between cropland and construction land were the major patterns of land use changes in the study area.
