Abstract: A good ecological environment is the basic condition of human survival and development. A scientific evaluation on ecological environment is the premise to protect the environment and promote the sustainable development of mankind. This paper reviews the advances of ecological environment assessment, introducing the application trend of remote sensing in evaluating ecological environment quality, and comparing the current methods of constructing evaluation index system, including analytic hierarchy process (AHP), principal component analysis (PCA), etc. The advantages and disadvantages of different assessment methods and models were analyzed, such as index evaluation method, fuzzy discrimination method, etc. It is necessary to grasp the characteristics of the ecological environment, and understand the internal relations between the nature and various elements of the ecological environment comprehensively for an appropriate evaluation methods and models. Finally, the main problems and the future direction in the current ecological environment assessment research were summarized and analyzed.
