Summary:耕地质量潜力测算是土地整治项目设计的基础工作,其测算方法有待进一步研究。该文依据农用地分等方法和数据,利用自然等指数、利用等指数,构建可实现潜力测算模型,测算出经土地整治后自然等、利用等别提升的可实现潜力。以中江县土地整治项目进行了实证研究,在利用预评价法对项目区分等因素可改变和消除的幅度进行了可行性分析的基础上,测算了项目区耕地质量可实现潜力。结果表明,整治后项目区自然及利用等指数均可有所提升,分等单元的省自然等、利用等指数提升区间为171.24~605.34、89.30~232.96,国家自然等、利用等指数提升区间为161.10~471.67、62.26~162.09。按照划分等别区间分值转换后,省自然等、省利用等、国家自然等、国家利用等分别平均提升0.66等、0.63等、0.84等、0.62等。该研究方法符合当地土地整治实际情况,提高了耕地质量潜力测算的应用性,可为土地整治项目设计编制和耕地质量建设提供参考。

In order to scientifically calculate the feasible potential quality of cultivated land quality upgrade and improve the planning, design, and arrangement of land consolidation project, a new pre-evaluation method of promotion potential of arable land quality was proposed based on the natural grade and utilization grade index of agricultural land gradation. The existing evaluation methods of improving potential of arable land quality are generally based on the natural grade and utilization grade index, and to set the top grade of arable land in a specified region as the target value of promotion potential calculation. The principle of existing methods is to assume that the limiting factors of arable land quality could be reduced or improved by land consolidation project. However, this assumption is not verified. This might cause the overestimate or underestimate of the evaluation results. The method we propos
