Abstract

Abstract: In this paper,the Bin county of Heilongjiang province was taken as study sample.Meanwhile,the Landsat TM image and DEM data were used as the main data sources,with the spatial module of ArcGIS,the analysis was made by using land use types and terrain factors from DEM,the spatial pattern distribution of land use was explored by analyzing the terrain factors of elevation,slope and aspects,and the study results can provide important science support for rational land use of this region.The study results show that the total area of cropland and forestland occupied the absolute dominate position of this study region.Which accounted for 91.20%,the cropland has the greatest area,which focused on flat ground,sunny and low elevation region.While,the forest land has the second greatest area,which is distributed in all rranges of terrain factors for slope,elevation and aspects.Meanwhile,the grassland,water,built-up land and unused land were mainly located in flat area and low elevation region.The area proportion of the good eco-environment quality was 34.16%,which was mostly occupied by forestland.The region of bad and worse eco-environment quality was plain areas,which occupied area proportion for 36.99% and 9.65%,respectively.

Key words: RS, GIS, digital elevation model, land use, eco-environment evaluation
