基于SOFM网络的农村居民点节约用地驱动类型研究

Study of Drive Type of Rural Residential Intensive Land Use Based on SOFM Network

提高农村居民点节约用地有助于释放农村建设用地潜力。从区域发展对农村居民点用地影响的角度出发,分析了农村居民点节约用地的驱动类型。首先,采用回归分析的方法,从中国国家尺度构建指标体系,分析农村居民点人均用地面积的主要影响因素;其次,借助Matlab 7.6软件、采用SOFM网络分析方法从宏观区域层面对中国各省域农村居民点节约用地的驱动类型进行划分。研究结果表明,中国省域农村居民点节约用地的驱动类型可以划分为4种类型:区域发展负向驱动、区域城镇化负向驱动、区域经济负向驱动和区域发展正向驱动;且从全国来看,在农村居民点节约用地驱动问题上出现了较显著的"马太效应"。

The improvement of rural residential intensive land use helps to release the potential of rural construction land. In order to analyze the drive type of rural residential intensive land use, this study, from the perspective of regional development impact of rural residential land departure, firstly uses regression model to construct the index system from the national scale, and analyses the main impacts factors of farmers per capita settlements land area. Secondly, this study with Matlab 7.6 software, using SOFM network analyses methods, drive type of rural residential intensive land use has been divided from the macro regional level. The results show that the provincial rural residential intensive land use drive type can be divided into four types, namely, regional development negative drive type, regional urbanization negative drive type, regional economy negative drive type, and regional development forward drive. And from a national perspective, there have been significant ＂Matthew effect＂ on rural residential intensive land use.
