Abstract:

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 mainland China. 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.

Key words: arable land readjustment, potentiality evaluation, the index system, Yanqing county
