由于人口的增加,加大了粮食的需求,从而不断的以草地为代价来扩大耕地面,草场面积的减少,单位牲畜占有草场的量不断下降,就会导致超载,引发草原退化、沙化,人口的增加也会刺激对肉类的需求,为了满足种种需求,牲畜的数量不断增加,最终导致土地沙化。 - Firstly , most theoretical researches and practical explorations deal with the farmland consolidation practices in northern plains and correspondingly farmland consolidation project planning and design in southern hilly region is less involved . secondly , farmland consolidation , however , has just begun in china and it mainly aims to increase agrarian areas in a majority of regions , not yet to attain the sustainable utilization of land resources based on the project analyses . behind the current " positive increase " in economic benefits , the truth is the " negative increase " in ecological , social and economic benefits in the long run
然而现阶段我国在农地整理的研究上还存在一些不足之处：一是这方面的理论研究与实践探索目前还主要集中在北方平原地区，对南方丘陵地区的农地整理规划设计探讨得比较少；二是在当前我国农地整理项目规划设计的实践中还普遍存在一些问题，大多数地区农地整理目标仍主要是扩大耕地数量，补偿因非农建设占用的耕地，尚未进入以项目分析为基础，以土地资源的可持续利用为目标的阶段，一些反映近期经济效益的喜人的“正数增长”后面，往往掩盖着长远的生态效益、社会效益和经济效益等方面的“负数增长” 。
