贡觉县森林植被及土壤分布规律研究

Study on Forest Vegetation and Soil Distribution in Gongjue County

贡觉县属藏东高山峡谷区,特殊的自然条件和地理环境,直接影响到水热条件在地域空间上的重新分配,导致水热条件差异明显,从而影响到植被和土壤的分布规律,而干热河谷的出现使得植被和土壤在垂直分布上不同于其他区域。研究该区域的植被和土壤分布规律,对于天然林保护、造林规划、造林树种选择及引种栽培工作,都具有极其重要的指导意义。

Gongjue county belong to eastern Tibet alpine gorge area, special natural conditions and geographical environment, resulted in significantly different hydrothermal conditions, thus affected the distribution of vegeta- tion and soil. Topography directly affected reallocation of the hydrothermal conditions in geographic space, the emergence of dry and hot valley made vegetation and soil in vertical distribution was different from other re- gions. Study on the distribution of vegetation and soil, is extremely important for protection of natural forests, afforestation planning, tree species selection, introduction and cultivation of tree.
