Because of the bottleneck of land resources and environmental problems with the rapid development of economy in China recent years,more and more researchers begin to focus on the carrying capacity of regional land resources based on the comprehensive evaluation from the perspective of economy,society,and environment. The evaluation method of land resources carrying capacity named SEP model was established from three aspects: carrying strength,carrying efficiency and carrying potential and using fuzzy evaluation as quantitative evaluation method in this article. As case study,this article evaluated the land resources carrying capacity of Minhang District in Shanghai. The evaluation results show that the carrying capacity of land resources in Minhang District has been in the alert and general level since 2000,and the carrying strength has been at the alert level since 2005,which is the key factor to limit the land resource carrying capacity of Minhang.
