中国西南丘陵区耕地整理潜力及其挖潜策略——基于重庆市合川区的调查

Potentiality of farmland consolidation and development strategy in southwest hilly area in China:A survey in Hechuan district,Chongqing city

基于新增耕地系数的数量潜力测算法、农用地分等因子提高后的质量潜力预评法,以及重庆合川的调查数据,对中国西南丘陵区的耕地整理潜力及其挖潜策略进行分析。结果表明:中国西南丘陵区耕地整理潜力整体较大,浅丘平坝区潜力值>0.6;低山丘陵区潜力值0.3~0.6;丘陵边缘山地区潜力值<0.3。进一步挖掘耕地潜力应基于耕地整理潜力予以分区并采取不同策略:对近期重点整理区,统筹安排项目配套政策及资金;对中期适宜整理区,通过提升基础配套设施水平来提高耕地整理潜力;对远期一般整理区,建立专项整理基金和拓宽耕地整理资金的筹措渠道。

Based on the quantity potential calculation method on increased farmland coefficient,the pre-evaluation method of increased agricultural land classification factors and with the data of Hechuan district,Chongqing city,this study analyzed the quantity potentiality and quality potentiality of farmland consolidation in southwest hilly area and its development strategy.The results show that the potentiality of farmland consolidation in China's southwest hilly area is relatively large;the potentiality of the shallow hill area is less than0.6,while that of the low hilly area0.3~0.6and the hilly edge area is less than0.3.According to these results,it is suggested to divide the farmland into three regions according to different potentials and put forward developing strategies.Specifically,to enhance the overall arrangement of the supporting policy and funds for the area needed arranging in short term,to improve the supporting infrastructure in the appropriate area planned in medium term,and to set up special fund for consolidation as well as broaden financing channels for farmland consolidation for the land needed arranged in later period.
