采用潜能模型的农村居民点布局优化

Optimizing spatial distribution of rural settlement based on spatial potential model

针对农村居民点用地布局优化研究未考虑规划影响的问题,该文提出了集成空间相互作用理论与规划影响的方法。首先参照城镇发展规划对农村居民点类型进行划分,然后依据新农村建设的要求和研究区的实际情况,从发展基础、生产条件、生活条件和生态环境4个方面建立了农村居民点潜能评价指标体系,根据修正后的潜能模型计算各农村居民点的潜能值,将孟河镇农村居民点划分为城镇化型、中心村、基层村、拆并村4种类型。在对农村居民点类型微调后,针对不同的类型提出相应的布局优化方案,对推进农村居民点整理具有一定的指导意义。

Since the impacts of land use planning were not considered in the research of optimizing spatial distribution of rural settlement, a method of integrating spatial interaction theory and planning im- pacts was proposed in this paper. First of all, the type of rural settlement was divided referring to urban development planning, then according to the requirements of new rural construction and the reality of study area, the indicator system of rural settlement potential evaluation was established from development foundation, production conditions, living conditions and ecological environment. The potential values of rural settlements were calculated according to the revised potential model, and four kinds of rural settle- ment land optimization types were got with the help of multi-factor comprehensive evaluation method in SPSS. urbanization type, central village, maintaining village, and relocation village. Optimal layout scheme was proposed for different types after types adjustment, which could propel the evolution of theo- ries and practices of rural settlement land consolidation forward.
