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.
