【摘要】：以平江縣為研究區域,運用“社會-經濟-環境”復合生態系統理論、多目標協調理論和可持續發展理論,從縣域土地利用空間格局和環境安全格局出發,采用層次分析法和GIS技術,構建了以土地生態適宜性分析為核心內容的平江縣生態縣規劃方法。主要研究結論如下：(1)建立了基于GIS的生態縣建設規劃空間數據庫和屬性數據庫平臺。通過資料收集與現場調查,運用GIS技術對平江縣國土局提供的土地利用現狀和基本農田保護的Mapgis格式數據進行轉換,經濟社會統計數據進行處理,轉換成各項柵格數據,并將各項影響平江縣土地利用適宜性分析的柵格數據統一入庫,建立了基于GIS的生態縣建設規劃空間數據庫和屬性數據庫平臺。該平臺數據庫包含了基礎數據庫、自然環境數據庫、環境安全數據庫和社會經濟數據庫。(2)建立了平江縣生態適宜性分析的分析指標體系。通過篩選指標的整體性、可行性、適應性和選擇性原則,從自然環境因素、環境安全因素和社會經濟因素這三大因素中選擇了坡度、坡向、高程、水文區位、基本農田、與自然災害點距離、土地利用、交通區位、與城鎮的距離、森林覆蓋率和人口密度共11個指標構建出整個分析指標體系。(3)2014年平江縣土地利用生態適宜性綜合評價。通過層次分析法確定各指標權重和通GIS空間疊加技術,建立加權求和的生態適宜性綜合評價模型,開展了土地生態適宜性綜合評價。根據綜合評價結果繪制土地利用生態適宜性綜合評價圖,計算各類型土地利用面積,其中適宜城鎮建設用地的面積為358.875km2,適宜村莊建設用地的面積為1119.176km2,適宜生態農業建設用地的面積為132.669km2,適宜生態林業建設用地的面積為2269.648km2,適宜生態工業建設用地的面積為234.062km2。(4)平江縣土地利用生態適宜性綜合評價結果,作為平江縣生態產業、生態人居規劃的成果與依據,為縣域城鎮建設、工礦與交通布局、農林開發提供了科學方法和依據。
[Abstract]:Taking Pingjiang County as the study area, using the "the theory of ecological system of society economy environment, the multi-objective coordination theory and sustainable development theory, from the perspective of land use spatial pattern and environmental security pattern, using AHP and GIS technology to build the ecological planning and ecological method as the core content of Pingjiang county the analysis. The main conclusions are as follows: (1) the establishment of GIS ecological county construction planning spatial database and attribute database based on the platform. Through data collection and field investigation, the use of GIS technology in Pingjiang County Land Bureau of land utilization and basic farmland protection in the Mapgis data format conversion and processing of economic and social statistics the data is converted into the raster data, and the effect of land use in Pingjiang county is suitable for storage of raster data unified analysis, established students based on GIS State county planning and construction of spatial database and attribute database platform. The platform database contains basic database, natural environment database, environmental safety database and social economic database. (2) the establishment of the Pingjiang County ecological suitability analysis index system. Through the whole, screening indexes of feasibility, adaptability and selectivity principle, from the natural environment safety factors, environmental factors and social economic factors of these three factors in the choice of slope, slope, elevation, hydrological location, basic farmland, distance, and natural disasters, land use, traffic location, and urban distance, the forest coverage rate and population density of a total of 11 indicators to construct the whole analysis index system. (3) the land use suitability evaluation in Pingjiang County in 2014. Through the analytic hierarchy process to determine the weight of each index and GIS spatial overlay technology, a weighted summation of the ecological suitability The comprehensive evaluation model, carry out a comprehensive evaluation of land ecological suitability. According to the comprehensive evaluation results of mapping of land use suitability evaluation, calculation of various types of land use, which is suitable for urban construction land area is 358.875km2, suitable for the village construction land area is 1119.176km2, suitable for ecological agriculture construction land area for 132.669km2, the suitable ecological forestry construction land area is 2269.648km2, suitable for the eco industrial construction land area of 234.062km2. (4) by the Pingjiang county land ecological suitability evaluation results, as the ecological industry in Pingjiang County, the results and basis of ecological human settlements planning, urban construction of county, mining and transportation layout, provides the scientific method and basis for the development of agriculture and forestry.
