Evaluation of Urban Land Comprehensive Carrying Capacity in Xi’anCity Under the Process of Urbanization

This paper attempts to establish an evaluating index system of land comprehensive carrying capacity in Xi'an city involving three aspects, such as economic carrying capacity, social carrying capacity, and ecological carrying capac- ity, combined with the development goals and constraint factors of Xi'an city. Furthermore, we adopted the method of mean-squared deviation weight decision to evaluate the status and dynamic change of land comprehensive carrying capac- ity in Xi'an City under the process of urbanization. As the results indicated, the index of land comprehensive carrying ca- pacity in Xi'an city shows an overall upward trend with a low starting point between 2001 and 2012. The index of land comprehensive carrying capacity in Xi'an city was at a high level in 2012, while that of ecological carrying capacity was at a low state with only 0.3521. Therefore, with the development of urbanization it is significant to improve urban eco- logical environment, and then to strengthen rational planning and adjustment of land use for enhancing land comprehen- sive carrying capacity, as well as for realizing sustainable urban development of Xi'an city in the future.
