【摘要】 针对目前北京市丰台区土地利用中存在着城市建设用地规模扩张迅速,耕地面积逐年减少等问题,在设计区间数多目标优化算法的基础上,建立了丰台区土地利用多目标优化模型,确立了三个目标函数及其相应的约束条件,并对丰台区土地利用结构的优化调整进行了计算分析,结合相关政策分析设计了土地利用结构调整方案,即适当扩展园地的面积;需要继续减少农村居民点用地;同时扩大城镇用地面积以适应城市化发展的需要;进一步减少独立工矿用地;交通和水利设施用地可以适当增加;特殊用地面积保持不变等.调整后的土地利用结构更能适应目前丰台区发展的需要.更多还原

【Abstract】 Adjustment of land use structure is an important part of land use planning.Now,many problems related to land-use are brought up in Fengtai district of Beijing,such as rapid expansion of construction land scale,reduction of cultivated area year by year and so on.After designing the method of interval number multi-objective optimization,three objective functions and corresponding constraint conditions were built. In addition,optimization adjustment of land use structure in Fengtai district was calculated and analyzed. According to related policies,the adjustment schemes of land use structure were presented,including expanding the area of garden plot,and urban land to meet the need of urbanization development,continuing to decrease rural residential land,industrial and mining land,increasing traffic and water conservancy facilities properly,and keeping the area of special land.The adjusted land use structure can meet requirements of the development of Fengtai district.更多还原
