Based on the ana lysis of current situation of farmland utilization,a system for assessing the performance of farmland utilization was established in this paper.

The results show that the index of land use performance increased from 0.

TA four-dimensional model for evaluating the land use performance was built with taking the index of land use intensivism land use degree,land use efficiency and land use benefit as variables,the evaluation index system was constituteed by choosing 23 evaluation index.

Time-sequence characteristics of the annual changes of the agricultural land use in China during the period 1980~2002;

Based on the value cost databases of the main crops such as paddy,wheat,maize,cotton,flue-cured tobacco,sugarcane and beet,this paper studied the changing characteristics of the agricultural land use intensity in China during the period 1980-2002.

Based on the cost-income data (1980-2002) of farm produce and the China Agricultural Yearbook, taking these main crops in the progress of the arable land use as a case study, this paper studied the regional differences in the changes of the agricultural land use in China during the period 1980-2002 from three aspects as the degree of intensity, the sown area and the abandonment of the arable land.

Townification,the process of rural population and resources moving into towns,is sure to exert profound influences on the utilization of agricultural land and cause a series of problems.

Land is the foundation of agriculture, and the utilization of agricultural land is essential to regional development.
