西藏三江流域干热河谷区臭椿适应性分析

Adaptability Analysis of Ailanthus altissima in Dry-hot Valley of Three Rivers in Tibet

通过查阅文献资料，分析臭椿的生物生态特征，对西藏三江流域干热河谷区海拔在2500～3200 m间土壤、气候、生态幅相似种进行分析，探讨臭椿在干热河谷区的适应性，结果表明：臭椿基本适应研究区域的土壤、气候环境，可开展育苗试种工作，为今后西藏干旱河谷区造林绿化在树种选择上提供理论依据。

Based on collecting literatures on Ailanthus altissima and soil,climate in dry-hot valley during alti-tude 2 500~3 200 m,the paper analyzed adaptability of Ailanthus altissima and drew the conclusion that Ai-lanthus altissima adapted the soil,climate environment in dry-hot valley,the seeding could be lauched,so as to provided theoretical basis for forestation of dry-hot vallys in Tibet.
