摘要
上海市土地资源紧缺成为城市化发展的瓶颈,对农村居民点的空间布局特征分析为上海土地利用结构优化提供参考意义。本文运用数理统计、计算几何、空间分析多种方法有机结合,分析1990-2015年的农村居民点的整体规模变化和空间演变特征。结果表明:上海城市化的扩张一定程度上是建立在农村居民点的集中规划基础上;农村居民点Voronoi图的Cv值远高于64%,是典型的集聚分布,但因受创业热潮和人们对居住环境要求水平提高等因素的影响,整体的Cv值在降低,分布的随机性在变大;崇明区的农村居民点在西北—东南分布密集,东南方向为扩展的热点方向;主体区的农村居民点总体布局较为均匀,在东—西方向更为密集,近年向浦东新区扩展的趋势加强。
The shortage of land resources in Shanghai has become a bottleneck of urban development.The analysis of the spatial layout characteristics of rural settlements provides reference for the optimization of land use structure in Shanghai.Based on the combination of mathematical statistics,computational geometry,and spatial analysis,this study analyzes the overall scale change and spatial evolution characteristics of rural settlements in the years 1990 to 2015.The results show that:to some extent,the expansion of urbanization in Shanghai is based on the centralized planning of rural settlements;in the Voronoi diagram of the Cv value is much higher than the 64%,is a typical distribution of agglomeration,but because of the influence of entrepreneurship and people's living environment to improve the level of the influence factors of the whole.The value of Cv in the lower,random distribution in the larger;Chongming District agricultural settlements in the northwestsoutheast direction for hot dense distribution,southeast direction to expand;the main area of the overall layout is more uniform,to more intensive in the east-west,in recent years,the trend to strengthen the expansion of Pudong New Area.
