Environmental Assessment of Land Use Planning Based on Remote-sensing Technique and Geographic Information System in Zoucheng County

Since Land Use Planning’s (LUP) implement will have impact on local ecological environment, the environmental assessment of LUP (LUPEA) is essential. This article explored the feasibility and method of LUPEA based on the environmental sensitive analysis study under the support of remote-sensing (RS) technique and Geographic Information System (GIS) and had assessed the ZouCheng County Land Use Overall Planning Environmental Impact using the method above. Firstly, after the analysis of the local environment status in quo, the environmental individual factors of ZouCheng County were determined, which included soil erosion, biodiversity, water quality, land subside and drain basin pollution. Secondly, the drainage area, elevation hierarchical map and slope distributing map were extracted with the aids of SRTM3 data. After that, we constructed the contaminant burdening indices including chemical oxygen demand (COD) and waste water on the basis of local drainage area to measure drain basin pollution individual factors. Thirdly, the vegetation feature and land use/cover information were also extracted using LandSat TM image based on the supervised classification and manmachine interaction interpretation method. Fourthly, with groundwater, nature reserve, coal mining caving in risk thematic information and other data including extracted information above, the Environmental Assessment Database System was set up in GIS environment. After the overall evaluation of environment status, the comprehensive assessment map of ZouCheng county environment was acquired and was overlapped by the land use overall planning map subsequently. With the analysis of the environmental assessment and land use overall planning data, several conclusions were drawn as follows: (1) High sensitive areas are mostly located on the big slope and areas and mountains apt to lose water and soil; moderate ones, on groundwater resources, large contribution water body, nature reserve and coal mining caving in risk area; and low ones, on natural or manmade woods and relatively severe polluted basins. (2) Burdening contaminant of local drainage area is an important factor in industrial distribution layout. (3) Land use overall planning scheme of ZouCheng County was feasible in environment respect in first approximation. (4) It is of great significance to assess the LUP using RS and GIS Technology.
