中国耕地整理潜力评价初探——以北京延庆县为例

A preliminary study on China's arable land readjustment potential evaluation: a case of Yanqing county in Beijing

土地整理潜力评价是土地整理规划的基础性工作 ,是合理有效安排土地整理工作的根本依据。对耕地整理潜力进行科学评价是土地整理潜力评价的重中之重。本文以农业土地集约利用和耕地生产力原理为理论基础 ,对影响耕地整理潜力因素分成两个方面 ,即影响净增加耕地数量和提高耕地质量两个方面进行分析。在此基础上 ,提出了耕地整理潜力评价指标体系 ,并以北京市延庆县为案例 ,进行了实证分析 ,证明所建立的耕地整理潜力评价指标体系是可行的 。

In China ,s land use practice, land readjustment has contributed a lot to the realization of the rational disposition of land resource and to the improvement of the land use efficiency and the ecological environment. Meanwhile, land readjustment has caught increasingly concern in land use science research. Regarding land readjustment, one of the essential contents should be the potentiality of land readjustment, upon which land arrangement plan can be plotted. However, so far as the theoretical and empirical researches in China ,s mainland are concerned, few discussions on the connotation and evaluation methodology of land readjustment potentiality have been carried out and arable land readjustment as land readjustment potentiality has also been rarely dealt with in China's Mainland. Based on the review of arable land readjustment potentiality abroad, it is argued that the connotation of China ,s arable land arrangement potentiality can be defined in three respects as optimizing land structure,optimizing arable land structure and improving arable land productivity.To this end,we build arable land readjustment potential evaluation index system.Yanqing county located in northwest of Beijing is an important ecological zone.The land readjustment project jointly conducted by the Center of Land Consolidation and Rehabilitation of Ministry of Land and Resources with Holland is also in Yanqing county, where a case study was carried out. The result indicated that the evaluation index system is feasible, conforming to the actual conditions of Yanqing. Evaluation methodologies with special attention to arable land readjustment are introduced, which are expected to shed new light on relevant researches.
