摘要
农用地产能核算是农用地分等的深化与延续。农用地生产能力包括理论产能、可实现产能及实际产能3个层次。通过建立农用地分等单元标准粮理论单产和自然质量等指数的函数关系、标准粮可实现单产和利用等指数的函数关系,分别核算分等单元的理论单产及可实现单产,以此为基础核算区域理论产能及可实现产能。农用地实际产能主要是依据核算区域内指定作物单位面积产量进行核算。结合农用地产能核算研究方法,选取河南省开封县进行了农用地产能核算实际案例研究。最后,本文对农用地产能核算的相关技术问题进行了讨论。
Check of productive capacity of farmlands is an extension of graduation. The farmland productive capacity includes three levels, theoretic productive capacity, feasible productive capacity and actual productive capacity. This paper, by establishing some functions between theoretic unit production of standard crop and natural quality of farmland graduation, and between feasible unit production of standard crop and utilization index, verifies the theoretic unit production, feasible unit production, and based on this, the regional theoretic unit production, regional feasible unit production. The actual productive capacity of farmlands is verified mainly according to the unit production of specified crops in area. Taking a case study on Kaifeng county, Henan province, this paper verifies the productive capacity of farmlands and discusses some related technical questions.
