空间关联视角下山区乡村社区生活圈的模拟构建及基本服务要素供给效率评估

Simulation Construction of Community Life Circle and Evaluation of Basic Service Supply Efficiency in Mountainous Rural Communities from the Perspective of Spatial Correlation

乡村社区生活圈的规划配置通常采用“自上而下”的技术方法。山区地形复杂、交通不便,使得该方法得到的社区生活圈划定与现实有较大偏差。针对山区乡村社区生活圈的构建问题,计算乡村社区之间的空间关联度,同时基于空间关联度构建空间关联关系视角下的社区生活圈。以重庆市石柱县为例,在构建社区生活圈后,对乡村基本服务要素——幼儿园和小学进行社区生活圈供给效率评估。结果表明,对空间分散分布的小学类要素依托下的社区生活圈构建,空间关联关系影响不大,可通过构建乡村社区生活圈快速提升全域的基本生活要素基础保障供给能力;对空间集聚分布的幼儿园类要素依托下的社区生活圈构建,则与空间关联关系紧密,需要在乡村社区生活圈中纳入空间关联关系,才可有效提升基本生活服务要素的共享服务效能。

Due to the complex topography and inconvenient transportation in mountainous areas,the community life circle obtained by using the"top-down"method has a great deviation from the reality.In order to solve this problem,the study firstly calculates the spatial correlation of rural communities,and then constructs the community life circle from the perspective of spatial correlation.Taking Shizhu County of Chongqing as an example,the study calculates the supply efficiency of kindergartens and primary schools after the construction of the community life circle.The results show that spatial correlation has little influence on the construction of community life circles when service elements are spatially dispersed such as primary schools.In this way,constructing rural community life circles can rapidly improve the basic security supply capacity of the whole area.In contrast,when service elements are spatially agglomerated such as kindergartens,it is necessary to incorporate spatial correlation relationships into the construction of rural community life circles in order to effectively improve the sharing service efficiency of basic service elements.
