西藏干旱河谷生态恢复初步探讨

西藏干旱河谷在金沙江、怒江、澜沧江和雅鲁藏布江流域的中、上游高山峡谷地区分布广泛,生态环境十分脆弱,并有进一步退化的趋势。生态恢复是改善西藏干旱河谷生态的有效途径之一。通过查阅相关文献,根据生态恢复相关理论,结合我国干热干旱河谷生态恢复的研究现状,论述了西藏干旱河谷生态恢复的途经,并提出一些模式,旨在为西藏干旱河谷生态恢复工作提供理论依据。

The preliminary exploration of dry valley ecological restoration in Tibet

Dry river valleys in Tibet are widely distributed in the upper and middle of Jinsha River, Nu River, Lancang river and the midstream alpine valley of Brahmaputra. In recent years there ecological environment is one of effective ways to improve the ecology of dry valley in Tibet. Through refering to relevant literatures, with ecological restoration theory, combinating eco- logical restoration research status of the dry--hot and dry valley in china, this paper described detailedly the ways to ecological restoration for dry valley in Tibet, also proposing some models in order to provide theory basis for future research.
