摘要
耕地占补平衡政策自实施以来取得了许多成效,但也存在诸多问题。如何有效的评价耕地综合生产能力,构建耕地质量评价体系对于政策的优化具有重要的意义。本文基于可操作性、科学性、效率等方面的考虑,采用土地利用现状数据和土地适宜性评价成果,通过AHP法对五种耕地类型生产能力指数进行测算,依据不同适宜等级的生产能力指数,最终建立不同耕地类型在不同适宜等级的均衡因子矩阵,结合GIS空间分析最终建立耕地占补平衡质量评价模型。
The policy has played an important role from its raising, however there are some defects all the same. It is signifieative to build a quality evaluation system for evaluating the total throughput of arable land effectively. The paper took account of operable, scientific and efficiency rules, to calculate throughput indexes of kinds of arable lands and different indexes of kinds of suitability levels, and then built a matrix of different arable land types in diHerent suitability evaluation levels, finally the model of requisition-compensation balance was built with the help of GIS.
