    Abstract:

    The contradictions between resource and economic development have become increasingly prominent. Resource saving and its intensive use from the perspective of low carbon is a fundamental approach to enhance the ability of sustainable development. Taking Wuhan City as a study area, By literature referring method, the low-carbon perspective was combined with the land use characteristics of urban agglomeration to establish a sustainable land use evaluation index system. Integration of CSDEA(indicators coacervation) with entropy method was used to analyze each index value and get comprehensive evaluation result. An improvement program was obtained by further calculations. Results show that Huangshi, Huanggang, Xianning, Qianjiang Cities are relatively effective in the CSDEA of sustainable land use, while Xiantao, Tianmen, Xiaogan, Wuhan, Ezhou Cities are ineffective, with comprehensive evaluation values of 0.9849, 0.9791, 0.9725, 0.9574, 0.8082, respectively. The evaluation value is the lowest for Ezhou City that has nine big shortage indicators such as agricultural production. Indicators for Ezhou City needed to be reduced include the rural Engel coefficient, garbage transport volume and other five indicators, of which carbon emissions should be reduced to 97.33t/hm2. Overall, Ezhou City should be greatly improved in sustainable land use. The evaluation results objectively reflect the status and lack of urban agglomerations land use and improvement program. In economic development, more attention should be paid to environmental protection and intensive and economical resource utilization and continuously improve the capacity for sustainable development.
