基于自然资源监测监管的成都市购房热点与城市社会空间结构探测

Chengdu’s Hot Spots of House Purchase and Urban Social Space Detection based on Natural Resources Monitoring and Supervision

摘要: 在城市地区，购房是一种常见的现象，关联到购房人的微观尺度运动。它反映了人们如何与社会或物理环境互动，也是一种重要的投资行为。研究基于四川省自然资源综合信息平台的不动产统一登记数据，以地理信息图谱理论为基础，提取每个权利人的购房时空信息，以空间密度热点探测为手段，从微观尺度上研究大量个体购房变化的热点区域和所形成的社会空间结构。从结果看，不同套次的空间结构，反映了权利人所处一定的社会等级和一定的经济等级时的购房选择行为，该行为与自然环境、营商环境、发展战略等相互制约与反馈，形成了独特的社会空间结构，这种结构既受宏观政策的影响，又受个体选择的影响，其宏观和微观的互动对未来的规划编制、政策出台提供了新的思路和监管角度。

Abstract: In urban areas, buying a house is a common phenomenon; it associated microscopic exercise of buyers. It reflects how people interact with social or physical environments and it also an important investment of everyone. Based on the geo-information mapping, research extracts the purchase time and space information of each right holder through the unified real estate registration database based on the natural resources monitoring and supervision system.Using the spatial density hotspot detection, obtainthe hotspot regions of each point of houses purchasedby individual person. The hotspotregions of different number of houses purchased reflects the affordability of different social level and certain economic level. From individual scale, the research formed social spaces in Chengdu. The purchase behaviors form a unique social spatial structure that is constrained and feedback from the natural environment, business environment, development strategy, etc. This structure is affected by macro policies and individual behavior. This kind of macro and microscopic interaction provides new ideas and regulatory perspectives for future natural resources monitoring and supervision. The interaction will also help to formulate the land and space planning.
