研究林分分布在29058’ N lat之间。和79年<一口> 0 < /一口> 28年代;E长在海拔1500-2150米。森林密度980 ~ 1100 ind.ha-1。其中，橡树占了69-97%。乔木基部面积31.81 ~ 63.93 m2 ha-1。< em > R。 floribunda共享最大基部面积16.45和16.32 m2 ha-1，而Quercus leucotrichophora共享最大(35.69 m2 ha-1)。生物量和初级生产力的变化范围分别为481 ~ 569 t ha-1和16.9 ~ 20.9 t ha-1yr-1。 Of this, biomass and primary productivity of oak tree species accounted for 81 to 95 and 78 to 98%, respectively. Carbon stock and carbon sequestration ranged from 228 to 270 t ha-1 and 8.0 to 9.9 t ha-1yr-1, respectively. The share of oak tree species ranged from 81 to 94.7 and 79 to 97%, respectively. The diversity of tree species ranged from 0.03 to 0.16 in forest sites-1, 2 and 3. The diversity of oak species was 0.08-0.16 in all the forest sites. Thus it is concluded that among the oak tree species, Quercus floribunda and Quercus leucotrichophora were highly dominated in the studied forests. The climax form of oak dominated trees in the studied forest sites depicted slightly lower richness and diversity of tree species compared to the forests in the region and elsewhere. As far as dry matter and carbon of forests is concerned, these estimates are close to the earlier reports of forests in the region. Therefore, studied forests have the potential to increase the diversity, productivity and carbon sequestration of forest tree species by providing the adequate scientific conservation and management inputs.
