基于空间自相关的峰丛洼地乡村聚落集聚形态格局演变及其分区——以紫云县宗地乡为例

高度集聚是峰丛洼地区乡村聚落最明显的空间格局特征,其空间形态集聚分布是自然和人为因素共同作用的结果,可为乡村聚落分区管理提供基础依据。基于空间自相关理论,观测其聚落空间分布的关联性,分析聚落的空间集聚格局及其演变特征,结合乡村聚落相关整治规划原则,对宗地乡的乡村聚落采取适宜的分区管理方案。主要结论如下:(1)乡村聚落点规模、形状、分布均呈显著空间相关,正、负相关类型多以组团式分布;(2)不同的自然与社会经济特点区域表现出不同的集聚格局,地形地貌等自然条件控制下的乡村聚落规模、形状和分布的集聚区域空间一致性较强,而城镇化、工业化等人为过程则降低了其空间的一致性。据此可将乡村聚落分为3个管理区域,研究区东部低山丘陵区应发展特色农业管理区,适时调整优化乡村聚落用地结构以改善生产生活条件;研究区的南部地区应发展特色村庄发展管理区;研究区的西部地势相对较高区域应发展驱动产业用地管理区,道路通达性好,应因地制宜推行区域统筹的综合管理模式,实现乡村聚落的整合发展。

The Peak Cluster-depressions Rural Settlements Spatial Agglomeration Pattern Evolution and Zoning Based on Spatial Autocorrelation：A Case Study of Zongdi Township in Ziyun County

Highly concentrated is the most obvious spatial pattern of peak cluster depression rural settlement. The spatial form of agglomeration distribution is the result of both natural and human factors, it can provide the basis for the partition management of rural settlements.This paper observes the settlement space distribution and analysis settlement spatial agglomeration pattern and its evolution characteristics by relevance of spatial autocorrelation theory. Combined with the remediation planning principles, taking appropriate partition management program for Zongdi township. The results showed that:(1) the rural settlement scale, shape and distribution showed significant spatial correlation, positive and negative correlation are group type distribution type. Region show different patterns with different natural, social and economic characteristics. The regional spatial consistency of rural settlements size, shape and distribution of agglomeration is strong which is controlled by topography and other natural conditions. The consistency is low under the control of urbanization and industrialization. The rural settlements can be divided into 3 parts, the low mountain and hilly region in east can be characteristic agriculture management zone, the structure of rural settlements land use has to be adjusted in order to improve living conditions. Southern parts of the study area should be developed into characteristic village. Higher regional in the west should develop driven industry and implement integrated management model of regional planning with good road access to realize the integrated development of rural settlements.
