| 摘 要： | 随着社会经济的发展，耕地数量急剧减少和各项非农建设占用耕地面积不断扩大的矛盾日益突出，为解决人口高峰年的粮食安全问题，国家提出了实施耕地总量动态平衡战略，实现耕地总量动态平衡的重要基础之一就是耕地占补平衡。当前我国耕地占补平衡的关键问题是片面强调数量平衡，缺乏新增耕地的质量评价衡量标准，从而使我国的新增耕地质量总体趋于下滑，某些地区生态环境恶化。因此，确定耕地质量的衡量标准，建立耕地质量检验机制已成为耕地占补平衡的关键。本文根据农用地分等理论及方法，结合我国耕地占补平衡中所存在的问题，对耕地占补平衡的评价方法进行了初步探讨，并以广东省连州市为例进行实证研究，确定了连州市耕地占补平衡评价体系及测算方法，为在全国范围内实现可持续发展的耕地占补平衡提供依据。

| Abstract: | With the fast growth of the continuous development of social economy,the contradiction between the constant growth of the farmland utilization for non-agriculture construction and the rapid reduction of cultivated land day and day.In order to resolve the problems of food safety in the peak year of population,the government put forward the goal of dynamic equilibrium of total cultivated land.Cultivated land requisition-compensation balance is one of important basis of true total dynamic balance of cultivated land.The most serious problem of the balance of cultivated land in china is that the quality balance was overlooked while the quantity balance was considered,and there are no valid quality judgment standards on the new cultivated land.Under the situation,the quality of the new cultivated land and the environment in some areas has become worse.So the application of the result of the agricultural land appraisal is an effective way to resolve these problems.The cultivated land quality was selected as the research object from many contents which in great need of studying.What has been discussed in the paper is the problem of dynamic balance of the farm in our country,and initial efforts were also made in the discussion on the evaluation method of the dynamic balance for the farmland quality in accordance with the theory and the result of land gradation and classification.The article took Lianzhou County,Guangdong province as an example,launched the research of quality evaluation of cultivated land requisition-compensation balance,and set up the functional models of utilize class index-standard grain of unit in the areas:C_f=0.5212Y+55.744,and the equivalent coefficient of cultivated land requisition-compensation balance in the areas.The establishment of the calculation method and the technical proof realized the cultivated land requisition-compensation balance for sustainable development in our country. |
