Abstract: In order to promote the sustainable use of the land in Wuhan Metropolitan Area,to balance the level of land ecological security in all municipalities within the system,explore the status and differences of urban individual and the whole area. Therefore,based on the improved literature reference method and the DPSIR model,the evaluation index system of land ecological security of Wuhan Metropolitan Area was constructed,using principal component analysis to calculate the comprehensive value of urban land ecological security in 2015,then,compared the difference between the whole and the city level. The results show that:the overall ecological security level of Wuhan Metropolitan Area is good,but the development of cities within the group is relatively uneven. There is no direct linear relationship between urban scale,urbanization level and land ecological security level. According to the ecological security value, the nine independent cities that make up the Wuhan Metropolitan Area are divided into four ranks and the corresponding measures are given.

Key words: ecological security, Wuhan Metropolitan area, evaluation, principal component analysis
