摘要: 由于干扰对森林生态系统的发展和存在起着决定性作用,因此量化森林受干扰的程度十分重要。通过构建综合干扰指数,分析了龙虎山林场青椆混交林的干扰状态,结果表明:综合干扰指数能够很好地反映出林分现实状态与理想状态的生长差异,从而得出林分的受干扰情况;对5块样地的青椆混交林林分综合干扰指数分析显示,青椆由于种内干扰较为严重,需要适当地进行疏伐;枫香与樟树在局部地区可能由于人为干扰导致生长较差,需加强管护;白栎整体生长良好。

Abstract: Disturbance was very normal in nature.In order to quantify the extent of forest disturbed,this paper presented a new index called Integrated Disturbance Index,which can be used to express the degree of forest disturbed.Cyclobalanopsis myrsinaefolia mixed stand in Longhushan Forest Farm in Hunan has been taken as an example.And this study indicated that it was disturbed.And the theory of Charles Darwin showed that the intraspecific competition of species is the most intense,so we can make sure that the intraspecific competition of Cyclobalanopsis myrsinaefolia was the main interference factor.So thinning should be done to Cyclobalanopsis myrsinaefolia;Liquidambar formosana Hance and Cinnamomum camphora(L.)Presl were in poor growth because of people’s disturbance and Quercus fabri Hance grew well.

Key words: Integrated Disturbance Index, disturbance, Cyclobalanopsis myrsinaefolia, BP Model, crown breadth
