基于城乡统筹发展的建设用地结构优化研究——以河南省南阳市为例

Research of Construction-land Structure Optimization on Coordinative Development of Urban-rural Area——With Nanyang City as an example

统筹城乡发展,是我国"十一·五"国民经济发展规划的重要任务。调整和优化土地利用结构,不仅是实施统筹城乡发展、建立和谐社会的重要内容,也是缓解用地矛盾、提高土地利用综合效率的战略性选择。引入经济理论模型等对未来城乡建设用地结构进行动态模拟和预测,选取设计思路严密性等5个评价指标,并且以河南省南阳市为例,对方案进行优化比较分析,提出保障城乡建设用地结构优化的措施和建议。

The coordinative development of urban and rural areas is an important program in the 11th five-year economic development planning of China. Adjusting and optimizing land-use structure is not only an important content to implement coordinative development of urban and rural areas and build a harmonious society, but also a strategic choice to resolve land-use contradiction and increase land-use compensative efficiency. This paper adopts economic and academic model to dynamically simulate and fore- cast the future land-use structure of urban and rural in Nanyang City by selecting five evaluated indexes, including strictness of de- signed idea to compare the optimized projects. The paper also explores the measures to ,guarantee urban-rural land structure and optimized layout.
