description: The aims of this paper are to illustrate the meaning and method of comparing the evaluation result of cultivated land intensive use, and to improve levels of intensive cultivated land use. We first calculated standard grain realizable yield in different districts based on agricultural land classification. To examine this method's practical applicability, Jiangsu Province was used as an example for empirical research. The districts with higher realizable yield utilization intensity in Jiangsu Province are mainly in the areas of poor or general quality of cultivated land, and there is a lower rate in Sunan where the land has better quality. The level of cultivated land intensive use in Sunan is extremely unbalanced. The results of the evaluation are more accurate after eliminating the effect of cultivated land quality differences, and the indicators that we used also can eliminate the effect of planting structure differences to a certain extent.

abstractThe aims of this paper are to illustrate the meaning and method of comparing the evaluation result of cultivated land intensive use, and to improve levels of intensive cultivated land use. We first calculated standard grain realizable yield in different districts based on agricultural land classification. To examine this method's practical applicability, Jiangsu Province was used as an example for empirical research. The districts with higher realizable yield utilization intensity in Jiangsu Province are mainly in the areas of poor or general quality of cultivated land, and there is a lower rate in Sunan where the land has better quality. The level of cultivated land intensive use in Sunan is extremely unbalanced. The results of the evaluation are more accurate after eliminating the effect of cultivated land quality differences, and the indicators that we used also can eliminate the effect of planting structure differences to a certain extent.
