【摘要】：以平江縣為研究區(qū)域,運用“社會-經(jīng)濟-環(huán)境”復(fù)合生態(tài)系統(tǒng)理論、多目標(biāo)協(xié)調(diào)理論和可持續(xù)發(fā)展理論,從縣域土地利用空間格局和環(huán)境安全格局出發(fā),采用層次分析法和GIS技術(shù),構(gòu)建了以土地生態(tài)適宜性分析為核心內(nèi)容的平江縣生態(tài)縣規(guī)劃方法。主要研究結(jié)論如下：(1)建立了基于GIS的生態(tài)縣建設(shè)規(guī)劃空間數(shù)據(jù)庫和屬性數(shù)據(jù)庫平臺。通過資料收集與現(xiàn)場調(diào)查,運用GIS技術(shù)對平江縣國土局提供的土地利用現(xiàn)狀和基本農(nóng)田保護(hù)的Mapgis格式數(shù)據(jù)進(jìn)行轉(zhuǎn)換,經(jīng)濟社會統(tǒng)計數(shù)據(jù)進(jìn)行處理,轉(zhuǎn)換成各項柵格數(shù)據(jù),并將各項影響平江縣土地利用適宜性分析的柵格數(shù)據(jù)統(tǒng)一入庫,建立了基于GIS的生態(tài)縣建設(shè)規(guī)劃空間數(shù)據(jù)庫和屬性數(shù)據(jù)庫平臺。該平臺數(shù)據(jù)庫包含了基礎(chǔ)數(shù)據(jù)庫、自然環(huán)境數(shù)據(jù)庫、環(huán)境安全數(shù)據(jù)庫和社會經(jīng)濟數(shù)據(jù)庫。(2)建立了平江縣生態(tài)適宜性分析的分析指標(biāo)體系。通過篩選指標(biāo)的整體性、可行性、適應(yīng)性和選擇性原則,從自然環(huán)境因素、環(huán)境安全因素和社會經(jīng)濟因素這三大因素中選擇了坡度、坡向、高程、水文區(qū)位、基本農(nóng)田、與自然災(zāi)害點距離、土地利用、交通區(qū)位、與城鎮(zhèn)的距離、森林覆蓋率和人口密度共11個指標(biāo)構(gòu)建出整個分析指標(biāo)體系。(3)2014年平江縣土地利用生態(tài)適宜性綜合評價。通過層次分析法確定各指標(biāo)權(quán)重和通GIS空間疊加技術(shù),建立加權(quán)求和的生態(tài)適宜性綜合評價模型,開展了土地生態(tài)適宜性綜合評價。根據(jù)綜合評價結(jié)果繪制土地利用生態(tài)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(zhèn)建設(shè)用地的面積為358.875km2,適宜村莊建設(shè)用地的面積為1119.176km2,適宜生態(tài)農(nóng)業(yè)建設(shè)用地的面積為132.669km2,適宜生態(tài)林業(yè)建設(shè)用地的面積為2269.648km2,適宜生態(tài)工業(yè)建設(shè)用地的面積為234.062km2。(4)平江縣土地利用生態(tài)適宜性綜合評價結(jié)果,作為平江縣生態(tài)產(chǎn)業(yè)、生態(tài)人居規(guī)劃的成果與依據(jù),為縣域城鎮(zhèn)建設(shè)、工礦與交通布局、農(nóng)林開發(fā)提供了科學(xué)方法和依據(jù)。
[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.
