中国耕地整理潜力测算分析

摘要

Land consolidation plays an important role in increasing cultivated land.Therefore,the paper proposed a method to measure the cultivated land consolidation potential in China.Meanwhile,based on survey data of land use changed in 2008,the farmland classification data and background information of typical project of cultivated land consolidation,the potentials of the cultivated land consolidation were evaluated qualitatively and quantitatively at the county scale.The results proved the considerable and concentrated potential capacities in China.The counties with high quantitative potential mainly distributed in Heilongjiang and Jilin in northeast China,Henan,Anhui and Hubei in the east,Sichuan,Guizhou and Yunnan in the southwest,Xinjiang in the northwest; Those with high qualitative potential were in Heilongjiang in the northeast,Xinjiang,Inner Mongolia and Ningxia in the northwest,Shandong and Anhui in the east,Hubei and Hunan in central China,Guizhou,Sichuan and Yunnan in the southwest.The study can facilitate recognition about distribution of the potentiality and designation of the key regions of cultivated land consolidation in China,and can provide data reference for planning national comprehensive land management.%耕地整理是增加耕地面积的重要途径,该研究提出新形势下中国耕地整理潜力的测算方法,并以2008年中国土地利用变更调查数据和中国农用地分等数据为基础,结合耕地整理典型项目区的资料等,以县为单位,对中国的耕地整理数量潜力和质量潜力进行了测算.结果表明,中国的耕地整理的数量和质量潜力巨大,耕地整理的数量潜力和质量潜力呈现较一致的集中分布特点.数量潜力较高的县主要分布在东北地区的黑龙江省和吉林省,东部地区的河南、安徽、湖北省,西南地区的四川、贵州、云南省和西北地区的新疆地区；质量潜力较高的县主要分布在东北地区的黑龙江省,西北地区的新疆和内蒙古和宁夏地区,其次是东部的山东省、安徽省和中部的湖北省、湖南省,西南地区的贵州、四川、云南省的潜力也较高.研究结果对掌握中国耕地整理潜力分布特点和确定中国的耕地整理重点区有指导作用,并可为编制中国土地综合整治规划提供数据基础.
