南方丘陵耕地产能研究

Research on the Productivity of Cultivated Land in Southern Hilly Areas

为了适应新形势下对耕地产能内涵提出的更高要求,对研究区域内耕地产能核算指标体系及其核算方法进行了调整。以江西省奉新县为研究区域,采用新的指标体系与核算方法对县域内耕地进行重新评价,并将其与原成果进行对比。结果表明:采用新的核算方法,计算出产能指数变化范围为712~2451,且产能指数较高的乡镇集中在奉新县中东部地区,而指数较低的乡镇集中在奉新县西部;产能指数与国家利用等指数相比基本一致,具有一定的继承性,且更能更加凸显出“好地”与“差地”。

In order to adapt the higher requirements of cultivated land productivity,the accounting index system of cultivated land productivity and accounting method were adjusted.Taking Fengxin County of Jiangxi Province as study region,new index system and accounting method were used to reevaluate the intra-regional cultivated land and compare with the former results.The results showed that the variation range of productivity calculated by new accounting method was 712-2451,the towns with higher productivity were concentrated in the central and eastern areas of Fengxin County,and the towns with lower productivity were concentrated in the west areas of Fengxin County.The productivity index was basically identical with farmland utilization grade and had a certain degree of inheritance,and it could be used to differ good land from bad land.
