This paper applies the C2R model of DEA to evaluate the land use efficiency of 29 cities in Hunan Province, with the result that the urban land use efficiency is high in the province as a whole, and that it is higher in the east than in the west.

Based on the summary of the research results in evaluating land use efficiency,the paper presents a basic idea for the construction of the evaluation system of land use efficiency.

This paper concludes the main historical events affacting the variation of land use efficiency since the foundation of the People s Republic of China.

Then Taking Shan Dong province as an example, through the analysis of land use comparative advantage, land utilization efficiency, to find out the law of the course land conversion.

Then it estimates the using efficiency of cultivated land basing on the meaning of factorial loading.
