摘要

本研究在海拔300 ~ 2080 m的库曼喜马拉雅地区的4个主要森林(柚木林、萨尔林、松林和栎林)中进行。乔木总密度为470 ~ 916.67 ind. ha,基材面积为37.82 ~ 67.41 m ha。物种丰富度最高的地点为KD(17),最小的地点为MG(7)。β多样性指数最高的地点为KD林(5.46),最小的地点为BP林(3.12)。森林立地的更新状况从良好更新到差更新或无更新不等。MG位点的再生能力很差。树木、幼苗和幼树的比例分布表明,KD位点的幼苗密度最大。最小幼苗密度记录在MG点。这是由于该地点牲畜放牧压力很大。研究结果为保护和恢复沿海拔梯度的不同森林提供了基线数据,也将有助于制定喜马拉雅森林的保护策略。

Stand structure and regeneration status of tree species in four major forest types along an altitudinal gradient in Kumaun Himalaya, Uttarakhand
The present study was undertaken in four major forests (Teak forest, Sal forest, Pine forest and Oak forest) along an altitudinal gradient between altitude 300 m – 2080 m of Kumaun Himalaya. The total density and basal area of trees ranged between 470 ind. ha and 916.67 ind. ha and from 37.82 m ha to 67.41 m ha respectively. Maximum species richness for trees was reported at site KD (17) and minimum at site MG (7). The maximum beta diversity index was recorded for KD forest (5.46) and the minimum was reported for BP forest site (3.12). Regeneration status of forest sites varied from good regeneration to poor or no regeneration. Site MG was found very poor in regeneration. Proportionate distribution of trees, seedlings and saplings showed that site KD contained maximum density of seedlings in comparison with other sites. The minimum density of seedlings was recorded at site MG. This is due to heavy livestock grazing pressure at this site. The results of the study provide baseline data to conserve and recover different forests along the altitudinal gradient and will also help to formulate conservation strategies of forests in Himalaya.
