基于加权Voronoi图的三江平原垦地城镇空间重构研究
|
摘要
以国有农场集中的三江平原为对象,明确垦地城镇空间的现状构成与问题挑战;结合基础数据,运用SPSS软件计算获得22个地方城市的中心性强度值,以城市中心性强度值为权重,在Arcgis扩展模块下生成表达各城市空间影响范围的WVD,辅以契合实际的重构原则与修正方案,形成三江平原垦地城镇空间重构图,确定国有农场单元相对于地方城市的划并方案。
This paper takes the Sanjiang plain of the state-owned farms as the object which should be included in the planning of local governments and be implement simultaneously. How to make a reasonable division of farms and cities in a complex geographical space become the primary problem. Firstly, this paper makes clear the present situation of farms and cities and the challenge of space reconfiguration of them. Secondly, the comprehensive strength index system with 18 indexes is established, and comprehensive strength of 22 cities of Sanjiang plain are obtained by principal component analysis(PCA) and basic data. Thirdly, comprehensive strength is taken as the weight, and the weighted Voronoi diagram of Sanjiang plain cities is generated by Arc GIS software. Finally, the space reconfiguration diagram of farms and cities of Sanjiang plain is formed based on weighted Voronoi diagram and combined with the reconfiguration principle and the auxiliary correction factors. As a result, the division and confluence program of space in each farm land unit and cities is determined.
