Objective By evaluating the stands status characteristics to formulate the reasonable management measures for the typical forest types and lay a basis for upgrading and restoring forest ecosystem functions in the Xiaolongshan forest region.

Method Ten stand status indexes and π-value rule were used to evaluate the stand status characters of 5 typical forest types in Xiaolongshan forest region, including the vertical structure, horizontal structure, age structure, tree species diversity, stand density and stand growth, and so on.

Result The stand status of three forest types (Quercus and coniferous broad-leaved mixed forest in Baihuayinya, broad-leaved mixed forest in Wang'angou of Baihuaxianping and Pinus tabulaeformis natural forest in Longmenyaoba) was general status, their ω values were 0.478, 0.478 and 0.498, respectively; the stand status of Quercus broad-leaved mixed forest in Wang'angou of Baihuaxianping was in better status with ω value of 0.551; the stand status of coniferous and broad-leaved mixed forest in Maijidongshuigou was in a lower grade with the ω value of 0.235.

Conclusion The π-value rule of forest status can quantitatively describe the typical forest types in the Xiaolongshan forest area. The evaluation results are in line with the actual conditions of the actual forest. Based on the results, the operational measures are provided to promote forest stability and quality.
