The density with the biodiversity increasing shows " m " model. ( 3 ) the correlation analysis shows : elevation, slope, development stage and biomass are main factors which affect the biodiversity pattern in the research region. the biodiversity of the quercus aliena var. acutesrata community shows the patterns with the elevation and slope affecting : on sunny slope, the species diversity increases with the elevation increasing below the attitude of 1640m and its climax is at this attitude ( the diversity index h = 1. 68 ), upward this point, the diversity index descends slowly. the evenness shows ascend trend with the elevation upward, its climax point at 1800m ( the evenness index jsw = 0. 78 ), then descending after this point
（ 5 ）通過分析，銳齒棟群落生物量與生物多樣性呈現如下關系:在海拔1500一170枷范圍內，銳齒棟群落生物量與物種多樣性之間呈單峰曲線關系;在海拔1700一1900m范圍內，生物量與物種多樣性之間呈不明顯的波動關系;在海拔1900一2100m范圍內，生物量隨物種多樣性的增加而增大，通過對不同高程內生物量與物種多樣性分析發現，隨著海拔的上升，最大生物量對應的物種多樣性略有增加趨勢;在相同海拔和坡向條件下，生物量與物種多樣性之間也呈典型的單峰曲線關系;群落凈生產力與物種多樣性之間總體上也呈單峰曲線關系。
