Abstract: The status of researches in ecosystem services value assessment (ESVA) wasreviewed. The methods of ESVA could be classified into two categories from the aspect of evaluation process: direct and indirect, which are further classified into several subcategories. After analyzing the concept connotation, calculation, and application of each classified method, we put forward ten problems in ESVA. Finally, by summarizing the theory, methodology, and resultsexpression form of ESVA, we proposed three suggestions to strengthen the future research ofESVA:  comparative and comprehensive application of different methods for the assessment ofecosystem services value;  ecosystem services value assessment of the areas with sparse or novegetation;  the assessment of service value of complex ecosystems and the evaluation of ESVA at fine scale.
