贫困地区农用地整治潜力及分区研究——以宁夏同心县为例

Potentiality and Classification of Agricultural Land Consolidation in Poor Areas——A Case Study on Tongxin County of Ningxia

农用地整治是确保粮食安全、提升农用地综合生产能力的重要手段,科学合理地评价农用地整治潜力对于贫困地区土地整治重点工程项目的选址安排、助推地区脱贫富民具有指导意义。以宁夏典型贫困地区同心县为研究区域,借助Arc GIS空间分析等手段测算农用地整治潜力大小,并采用四象限法进行农用地整治潜力分级。研究结果表明:同心县农用地整治数量潜力为6 828.26 hm2,在可增加的耕地面积的基础上结合新增耕地系数,划分4个级别农用地整治潜力区,1级潜力区域主要集中在下马关镇、韦州镇和王团镇,2级潜力区域主要集中在张家塬乡和田老庄乡,3级潜力区域主要集中在丁塘镇、豫海镇和马高庄乡,4级潜力区域集中在河西镇、兴隆乡和预旺镇。研究结果为合理统筹农村土地整治任务,划分农村土地整治重点区域、重点工程项目提供理论依据和现实参考。

Agricultural land consolidation is an important means of ensuring food security and improving the comprehensive production capacity of agriculture land in China. Scientific and reasonable evaluation of agriculture land consolidation potential is of guiding significance for arranging key projects and helping to overcome poverty and tackle in poor areas.Taking Tongxin County in typical poor area of Ningxia as research area, with the aid of Arc GIS spatial analysis, the potential of agricultural land consolidation was calculated and classified by the four-quadrant method. The results showed that the increase of cultivated land area in Tongxin county was 6 828.26 hm2, on basis of the area of arable land that could be increased and combined with the coefficient of new cultivated land. The potential areas for agricultural land consolidation were divided into four levels. The potential areas of level 1 were concentrated in Xiamaguan Town, Weizhou Guan Town and Wangtuan Town;the potential areas of level 2 were concentrated in Zhangjiayuan Township and Tianlaozhuang Township;the potential areas of level 3 were concentrated in Dingtang Town, Yuhai Town and Magaozhuang Township;level 4 potential areas were concentrated in Hexi Town, Xinglong Township and Yuwang Town. The results provide theoretical basis and practical references for rational coordination of land consolidation tasks, division of key areas and key projects of land consolidation.
