宅基地置换是农民居住空间资源再分配和再组织的过程,是实现“节约土地资源、提高农民福利、增进社区和谐、改善居住环境”等目标的系统工程。本着“以人为本、公众参与、政府引导”的原则,本文在对农民居住空间需求和意愿调查的基础上,提出了居住空间资源合理化配置的定量分析方法和技术流程,并针对“总量—结构—分布”三个要素分别建立了以下三个模型:以总量控制为目标“实现社会福利最优”的容积率定量决策模型、以结构控制为目标“满足多样异质需求”的户型比例优化模型和以分布控制为目标“体现居民空间公平”的户型组合优化模型。跟进调查显示,本技术方法在青村镇宅基地置换项目中取得了良好效果,值得推广。
Homestead replacement is the process of redistribution and reorganization of peasants 'living space, and is a systematic project to achieve the goals of “saving land resources, improving peasants' welfare, enhancing community harmony and improving living environment.” Based on the principle of “people-oriented, public participation and government guidance”, this paper puts forward a quantitative analysis method and technological process of reasonable allocation of living space resources on the basis of surveying the demand and willingness of living space for peasants. Quantity-structure-distribution “, the following three models are respectively established: the volumetric rate decision model with the objective of total control as its goal and the” optimal social welfare as its goal “, with structural control as the target. Quality requirements ”and the proportion of households to optimize the distribution control model and“ reflect the residents of fair ”apartment layout optimization model. Follow-up survey shows that the method has achieved good results in the project of replacement of Qingcun town house sites and is worthy of promotion.
