Abstract：Based on the Principal Component Analysis,the 51 Pinus tabulaeformis sample plots were classified with Clustering Analysis,and the 51 sample plots' health status were assessed with the constructed integrated assessing model.The results indicate that the 51 sample plots could be clustered into 5 levels.Among all the Pinus tabulaeformis sample plots,6 are the excellent health（Ⅰ level）,12 are the good health（Ⅱ level）,11 are the general health（Ⅲ level）,18 are the sub-health（Ⅳ level） and 4 are the ill health（Ⅴ level）.Of the 6 excellent health sampling plots,5 are natural forest,only 1 is planted forest,all other healthy sampling plots are planted forest.The assessing method can reflect the health status of the sample plots objectively and operability,and it offers a certain reference to the forest ecosystem health management.
