Abstract: The sustainable use of land resources is the fundamental guarantee of social and economic development. 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. It calculated the index of land use performance of Zhanjiang city from 1996 to 2006 using the investigation data of land use change and social and economic statistic data, and evaluateed the land use sustainability. The results showed that the land use degree was a decreasing trend generally with higher level, but the land use intensity, efficiency, benefits were increased evidently. The land use performance was a steady growth trend with lower level, and the index of land use performance increased from 0.3172 in 1996 to 0.7163 in 2006. The sustainability indices were more than zero from 1997 to 2006 using 1996 as the base year. The land use was in the sustainable stage, which indicated that the utilization of land resources was being optimized gradually in Zhanjiang city. Regional distribution of land use performance and sustainability had a certain zonal characteristics. Finally, it puted forward some suggestions on land sustainable use according to the existing problem of land use.
