摘 要：
[目的]对东洞庭湖区域的优势树种马尾松林进行健康评价研究,为该区域科学经营森林,改善区域人居环境和生态环境建设提供参考和借鉴。[方法]依据马尾松林样地调查、岳阳市森林资源二类调查和湖南省林业资源信息系统获取马尾松林数据。并从生产力、结构性、可持续性及抗干扰性4个方面选择了马尾松林14个健康评价指标,依据方差贡献率确定指标权重,计算有代表性的329个马尾松林小班得分与既有的健康等级定性指标标准比较确定小班的健康状况。[结果]优质小班14个,健康小班76个,亚健康小班221个,不健康小班18个,分别占所选样本总面积的7.33%,24.62%,61.34%,6.71%。[结论]该区域马尾松林总体上处于亚健康与不健康状况;天然林健康状况好于人工林;混交林健康状况优于马尾松纯林;高海拔、陡坡、边远区域马尾松林健康状况明显优于低海拔、居民密集区域。

摘 要：
[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.
