Abstract：Forest is the main body of forestry and is a constituent part and essential measure of sustainable forest management. Forest health has attracted more attention at home and abroad, and became one of the important domains of forestry research. Based on the development history and connotation of forest ecosystem health, the main assessment methods of forest health were summarized in detail in this paper: index system method, ecological instructions method and health distance method.The merits and shortcomings of different methods were analyzed. In future researches, rapid diagnosis and assessment methods will be the key orientation, and the following aspects should be paid more attention: 1)to define the conception of forest ecosystem health; 2) to form simplified index systems of rapid diagnose and evaluation of forest health; 3) to establish methods for rapid diagnose and evaluation of forest health; 4) applied technology of rapid diagnosis and assessment of forest health; 5)studies on rapid diagnose and evaluation of forest health with multi-technologies, multi-methods and in multi-scales.
