广西农用地整理条件分区及其模式分析

农用地整理条件分区可为科学开展整理工作提供指导。该文基于整理潜力、生态环境、自然条件和社会经济条件4种因素构建评价模型,综合多项资料定量分析各因素因子状况,进而借助GIS平台,通过聚类分析与构建分区规则的方法,对广西农用地整理进行条件分区;运用该成果,以不同地域条件的需求为依据,分析出不同农用地整理模式的集合以及分布状况。研究表明,桂中和桂南地区整理潜力较高、各方面条件较好,是未来农用地整理的重点区域,适合较大规模低成本的高标准农田建设,非重点区域内坡耕地治理和生态防治是其重点,投资成本较高,桂林市与玉林市可尝试进行引入民间资本的一般规模中等成本整理模式。

Farmland consolidation conditional zoning and pattern analysis in Guangxi

Farmland consolidation zoning can guide consolidation project much more scientifically. An evaluation model of farmland consolidation zoning was established based on four factors of consolidation potential, ecological environment, natural conditions and socio-economic conditions, which were evaluated with multiple data. Based on GIS platform, the methods of cluster analysis and building principles of partition were used for farmland consolidation zoning by different conditions. Different patterns and their distribution were analyzed based on requirements of conditional zoning. The results showed that the potential of farmland consolidation was high and various conditions were good in central and southern Guangxi, which is the main area of farmland consolidation in the future, and suited for pattern of large-scale, low cost, high standard farmland construction. For other areas, slope modification and ecological prevention are important, but cost is higher. So it is worth of trying to introduce private capital for moderate scale consolidation in Guilin and Yulin.
