摘要
对小兴安岭东折棱河林场2种不同类型的红松林——椴树红松林和云冷杉红松林进行调查,应用重要值、辛普森多样性指数(Simpson’s diversity index)和香农-威纳指数(Shannon-Weiner index)对2种不同红松林乔灌草三层的生物多样性进行了分析和比较。结果认为,云冷杉红松林总体物种丰富度、信息量、生物多样性指数均高于椴树红松林。
According to the investigation and calculation of two different kinds of Korean Pine forest——Tilia Tuan-Korean Pine Forest and Spruce Fir-Korean Pine Forest in Dongzhelinghe state forest farm,Xiaoxinganlingthe,the biodiversity of tree layer,shrub layer and herb layer have been analyzed and compared,on the basis of the important numerical value,Simpson＇ s diversity index and Shannon-Weiner index.Results showed that species richness and biodiversity index of Spruce Fir-Korean Pine forest were higher than those of Tilia Tuan-Korean Pine forest.
