专业村集聚的空间测度——以河南省专业村为例

Spatial Measurement of Specialized Villages' Agglomeration:The Case of Henan Province

调查了河南省487个专业村,形成了487×71的属性数据矩阵。通过GIS可视化、LISA集聚图分析,得出结论:(1)专业村数量明显增多,空间集聚程度显著增强;(2)特色农业型专业村早在20世纪80年代之前就已形成集聚态势,工业型专业村集聚始于20世纪90年代,服务业型专业村最晚,为21世纪以来逐渐形成;(3)受进入门槛、特定环境、农户市场意识等影响,三类专业村集聚成因有明显差异;(4)在较大区域尺度上,专业村集聚程度较高地域并非出现在经济发达区。

Selected 487 specialized villages for investigation from Henan Province, and completed the data ma- trix of 478 ×71. By the use of ArcGIS software and LISA figure, find the conclusions as following： （ 1 ）The number of specialized villages increased obviously, and the degree of spatial agglomeration was strengthened. （2）The type of agricultural specialized villages occurred earlier than 1980s, and the trend of spatial agglomeration was obvious. The industrial specialized villages＇ agglomeration began in 1990s, and service industrial specialized villages＇ agglomera- tion formed after 21 century. （3）There were obviously different in reasons of three types of specialized villages＇ ag- glomeration, including barriers to entry, specific environments, and rural household market consciousness and so on. （4） The higher specialized villages＇ agglomeration did not occur in the developed areas in a larger scale, which gives a guiding significance for policy formulation of Chinese agriculture, rural areas and farmers.
