[Objective] The research on massion pine forest as superior tree species in East Dongting Lake area can provide the reference in scientific management for the regional forest, and improve regional environment and ecological environment construction. [Methods] The data about masson pine forest were gained through typical sublot survey, the second-class investigation of Yueyang forest resources and forest resources management information system in Hu'nan Province. The 14 indexes were selected and the index weight was ensured according to variance contribution rate. Then the score of sublots was determined by calculating represent 329 sublots compared with the existing health grade index. [Results] The evaluation results showed that the number of high quality sbulots was 14, healthy sublots was 76, sub-healthy sublots was 221, unhealthy sublots 18, possessing total area of the selected samples 7.33%,24.62%,61.34%,6.71%, respectively. [Conclusion] The masson pine forest in studied area was between sub-health and unhealthy in general; the natural forest health was much better than the plantation; the health situation of masson pine forest in high altitude, slope, remote area was significantly better than that in low altitude, dense population area.
