本文根据最小人均耕地面积和耕地压力指数理论，应用趋势预测分析和回归分析方法，建立研究区域粮食安全状况预测模型，进行预测分析研究。论文主要以陕西省关中地区为例进行分析与实践论证。结果为，1999年关中地区粮食处于安全状态，对于各个地区而言，西安和铜川的粮食状况不容乐观；而宝鸡、咸阳、渭南和杨陵区粮食状况相对安全。特别是杨陵区，在农业科技不断进步的作用下，耕地生产力水平提高，因此粮食状况最安全。

With the practice and research on the grade-determination of the cultivated land , the paper, based on the concept and purpose of the grade-determination of the cultivated land , has analysed the problems existing in the course of practice and summarized the reasons about " the rules of the grade-determination of farming land " which the Ministry of Land and Natural Resources had issued , including the issues about dependence between grading index of cultivated land and utilizing index ,or dependence between grading index of cultivated land and natural index , lack of the nationwide comparativity of the achievement on grade-determination of the cultivated land ,the sudden change indexes between the paddy field and its adjoint nonirrigated farmland, the representativeness of appointed crop and so on.

通过耕地分等的实践和研究，文章从耕地分等的内涵和目的出发，对国土资源部颁布的《农用地分等定级规程》在实践过程中所存在的问题及其原因进行了归纳和分析，其中包括耕地等指数与自然等指数、利用等指数的相关性问题，耕地分等成果在全国范围内缺乏可比性问题，相邻地块间水田和旱地的等指数出现突变问题，指定作物的代表性问题以及熟制问题等。

The reasonable consumption pace of tillable field resources is calculated by defining the logical development speed of economy in this paper.

经济的发展必然伴随著资源的消耗，耕地资源同样在经济发展过程中被不断消费，本文通过具体界定合理的经济发展速度以推算合理的耕地资源消费速度，并与我国耕地资源消费情况作比较，深入分析我国经济过程中耕地资源过度消费的外在形式以及内在原因，提出相关政策建议。

文章摘要：采用湖州市及所辖县市区50年统计数据，分析了湖州市耕地资源变化过程及区域差异，并定量分析了湖州市耕地资源变化与经济发展的关系，对不同经济发展水平耕地占用量进行了估算。

According to the systematic data on land use gathered in the 1996 survey,based on reverse deduction of the cultivated land area from 1986 to 1996,and deduction of the cultivated land area from 1960 to 1985 by stages by employing yield of grain,this paper redescribed the actual changing trend and character of Chinese cultivated land and analyzed the driving force of the policy relative to cultivated land to cult

结果表明，1949年以来中国耕地资源数量呈现波动性变化，但在1979年之前总体上是增加的，自20世纪80年代起呈现缓慢下滑，1999年后由于生态退耕等原因引起耕地数量迅速减少，由此导致的中国粮食安全问题与耕地安全问题值得关注。

In order to make the current grade-determination method of the cultivated land more rational, the paper has analyzed the natural and social economic factor of cultivated land quality deeply. Many ideas, including the theoretical foundation on grade-determination, the authenticity of the basic materials, the division of the index district, the determination of the appointed crops and their parameters , the largest theory output of the crop and the definition of the suitable range about index district, the control of the equivalence district in the county , the revision of the multiple crop index and the application of GIS ,etc. have been deeply discussed, and the current grading model of the cultivated land has been revised.

为使现行耕地分等方法更趋合理，本文以耕地质量评价的相关理论为基础，强调了基础资料对等别划分的重要性，明确了获取方法，并对指标区的划分、指定作物及其参数的确定，作物理论最大产量及其适用范围的界定，县域范围内等值区的控制，土地利用系数的修正、复种指数的修正和GIS在耕地分等中的应用等方法进行了深入探讨，修正了现行耕地分等模型。

The change of cultivated land use quantity shares the same direction with fluctuation of the budget of cultivated land use tax and is variating in the reverse direction of the variation of actual final account of cultivated land use tax.
