【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。更多还原

【Abstract】 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 regions,with certain maneuverability and could be the basis of the local government and the owner decision.更多还原
