摘要
本研究基于GIS平台利用叠加分析的方法提取安置区内的海拔高程、地面坡度、土层厚度和土壤养分等自然因子,得到土壤适宜性评价结果。然后在土壤适宜性评价的基础上,采用线性规划的方法,对移民安置区土地利用进行多目标规划。规划结果符合当地的实际情况,具有一定的可操作性,可作为地方政府和业主的决策依据。
This research withdraw the natural factors such as the elevation, ground slope, the soil layer thickness, the soil nutrient and etc. based on the GIS-Terrace by the method of overlay analysis, the soil feasibility evaluation results were obtained. Then on the foundation of the soil feasibility evaluation results, line programming of method, the many-target-programming of land-use in immigrant setting region. The programming matches the actual circumstance of the local regioas,with certain maneuverability and could be the basis of the local government and the owner decision,
