| 摘 要： | 根据贵州省凝冻灾害森林资源损失调查评估实施细则,就百里杜鹃自然保护区实际情况,选取具有代表性的受灾地块设置样方进行林木受损情况调查.调查显示:百里杜鹃自然保护区内普底花区的成灾面积比远远低于金坡花区;杜鹃林中马缨杜鹃受灾最严重,映山红(落叶)受灾最轻;大径级的杜鹃花受损较严重,林内出现大量的林窗,面积最大的达2 100 m2.从树种、林分结构、自然条件等情况,分析灾害产生的主客观原因;提出灾后重建应以杜鹃花区为重点,加强大径级杜鹃花的保护力度,林窗的生态恢复需采取自然恢复与人工干预相结合的措施. |

| Abstract: | To investigate and assess the snow storm damage in Baili Rhododendron Nature Reserve,sites were set in the typical areas based on the Implementation Details of Assessment and Survey of Loss of Forest Resources after Snow Disaster in Guizhou Province.The survey data showed that the damage in Jinpo flower area was more serious than Pudi flower area.R.delavayi was the most influenced one among the Rhododendron species,while R.simsii was the least one.The Rhododendron plants with large stem diameter were damaged more than that with the small one.Many gaps appeared in the region after the disaster,with the biggest one up to 2 100 m 2.The subjective and objective causes for the disaster were analyzed.To rehabilitate the nature reserve,attention should be paid to Rhododendron species and the habitat,especially to the larger plants.The restoration measures for the gaps should be a combination of natural process and human interference. |
