Abstract: Abstract: In order to enrich the theory of evaluation of land regulation potential and effectively guide the practice of rural land renovation，the article used the agricultural land regulation mode of high-standard basic farmland construction model as the starting point, constructing an evaluation system and method according to the potential of rural land under the high-standard basic farmland construction model combined with the evaluation of the land regulation potential and a special land regulation model. The paper based on the construction demand of high-standard basic farmland and subjective and objective analyses of a farmer's will, on the basic of discussed the research status about evaluation on agricultural land regulation potential, the agricultural land regulation potential evaluation mode should take the construction characteristic of high-standard basic farmland, the analysis and evaluation of the land regulation potential which take land regulation model as he starting point has certain innovation and pertinence in the study area of the research in this paper. The ChangShou District of Chongqing City was taken as the study area in the research. The promotion on quantity and quality potential of A (High-standard basic farmland construction areas) and B (Non-high-standard basic farmland construction areas) type regions was established by using the zoning methods of diversity survey, calculating confidence intervals, selecting potential levels, calculating cultivated land productivity, and calculating comprehensive indices of farmland quality. A comprehensive classification of agricultural land regulation potential was conducted according to the classifications of quantity potential and quality potential. The research shows that the quantity and quality potentials of type A regions are 551.78 hm2 and 2218.57 t, and type B regions are 1531.32 hm2 and 3883.77 t. The high-standard basic farmland construction areas are concentrated in second and third potential regions in the ChangShou District. According to the research, the potential structure of the agricultural land regulation mode based on high-standard basic farmland construction model obviously differs by regional type: the potential to increase cultivated land is limited due to the lower field index of cultivated land and slope ranges in a type region. Agricultural land regulation should focus primarily on exploiting quality potentials, and secondly on quantity potentials. Agricultural land regulation should focus on both quantity and quality potential for the relative poor quality of cultivated land and randomly distributed of the field in B type region, the cultivated land quality should be improved combined with rural collective construction land regulation and increase the quantity of cultivated land to meet the requirements in cultivated land balance and agricultural scale development. The potential evaluation in areas of high-standard basic farmland can be more pertinent, objective and nimble by using the zoning methods of diversity survey and selection methods of potential levels in the research. The reference can also be given for the potential analysis of making land regulation plans at the county level and the practice of land regulation. This work enriches and partially completes theoretical research on land regulation potential evaluation.
