摘要
通过对西双版纳国家级自然保护区曼搞片区计划烧除前后对3块暖性针叶林和2块季风常绿阔叶林的调查及监测结果显示,在曼搞保护区开展计划烧除,对各个群落内的乔木层没有影响,小乔灌层有一定的影响,高度在2m以下或基径3cm以下的幼树基本会被烧死,高度在2m以上的影响较小,草本层植物地上部分全部被烧死。但是在烧除后的3个月内,所有物种基本上都得到了不同程度的恢复,6个月后,所有草本植物的高度基本恢复到了恢复前的水平。通过分析认为,计划烧除对群落不会造成长时间的影响,通过计划烧除,可有效提高土壤养分,促进植物的生长,但是过多的丛生苗对林分的质量会有一定的影响。
Through the investigation and monitoring of three warm coniferous forests and two monsoon?evergreen broad-leaved forests before and after the planned burning of the Mangao Nature Reserve of the Xishuangbanna National Natural Protection Area,it was shown that the planned burning was carried out in the Mangao Nature Reserve.There is no effect on the tree layer in each community,and the small shrubs has a certain influence.Young trees with a height below 2m or a base diameter of 3cm are basically burned to death,and the height above 2m is less affected.The ground parts of herbaceous plants are all burned to death.However,within three months after the burning,all species have basically recovered to varying degrees.After six months,the height of all herbaceous plants has basically returned to planned burning ago levels.Through the analysis,it is concluded that the planned burning will not have a long-term impact on the community.Through the planned burning,soil nutrients can be effectively improved and the growth of plants can be promoted.However,too many clustered seedlings will have a certain impact on the quality of forest stands.
