文章摘要：

Forest diversity and conservation in the Wul- ingshan National Nature Reserve are ecologically impor- tant in North China. Forty-one forest plots of 20 m 9 20 m were established along an altitudinal gradient. Data on species composition, environmental variables and distur- bance intensity were measured in each plot. The TWIN- SPAN and CCA methods were used to analyze forest community diversity and the forest–environment relation- ship, and species diversity indices were used to analyze species diversity in this reserve. The results showed that eight forest formations were identified by TWINSPAN using species importance value data, and most of them were typical secondary natural forests. Each forest forma- tion had its own characteristics of composition, structure, function and environment. Forest diversity was most sig- nificantly correlated with elevation and disturbance, and was also related to litter thickness, soil depth and slope. The species diversity showed a ‘‘humped’’ distribution pattern along the altitudinal gradient and a quadratic decreasing pattern along the disturbance gradient. Eleva- tion and disturbance were the most important factors influencing species diversity. The effectiveness of conser- vation is apparent since the reserve was established.
