人为干扰对高黎贡山社区森林树种多样性的影响

Effects of human disturbance on the tree species diversity in community forest of Gaoligong Mountains.

研究人为干扰活动对高黎贡山社区森林树种多样性的影响结果表明 ,人为干扰对该社区森林有明显的负面影响 ,减少了群落树种多样性和破坏森林群落结构 ,降低森林资源量。当地居民对森林树种选择性的砍伐 ,使群落优势种组成发生变化 ,导致某些树种种群减小 ,物种生存受到极大威胁。并提出减少人为干扰的策略。

The effects of human disturbance on the tree species diversity in comm unity forests of Gaoligong Mountains show that the human disturbances cause nega tive impacts on the community forest,i.e.decreasing the tree species diversity a nd timber volume,as well as destroying the forest community structure.The forest community structure changes by selectively cutting,and some species population are declined and threatened ultimately.Finally,some countermeasures of reducing human disturbance are put forward.
