The purpose of the paper is to determine the concept of the environment-friendly land use, evaluation index system and suitable evaluation method. Methods employed include documentation, theory analysis, multi-index comprehensive evaluation, combination evaluation and statistic test. The results show that the paper set up a environment-friendly land use evaluation index system including 40 indexes with hierarchy and the TOPSIS of weights was proved to be the best evaluation method. The overall level of environment-friendly land use in Chongqing City showed an increasing trend year by year except 2005. It is concluded that the evaluation index system basically can reflect the state and level of environment-friend land use and the index system is relatively suitable for the evaluation of mode of environment-friend land use.
