| 摘 要： | 我国西南的干旱河谷是典型的生态脆弱带，生态系统退化严重，植被恢复/重建难度极大。概略介绍了干旱河谷气候、地质、土壤和植被特点，回顾和评述了植物个体、种群、群落与生态系统、景观生态学等方面取得的主要研究进展，并结合植被恢复的现状，提出了干旱河谷植被生态学研究应关注植被演替及退化机制、从植物功能属性为视角了解生态学过程和推演植物在不同尺度的适应机制、自然灾害对植被的影响、经济植物的开发利用等几点期望。

| Abstract: | Dry valley of southwest China is a typical ecologically fragile zone. It has been suffering from severe ecosystem degradation, and its vegetation has been damaging heavily. The vegetation restoration or reconstruction is extremely difficult. In recent years, a lot of theoretical and application-oriented researches have been performed in order to scientifically and technologically support the management of the ecosystem degradation. In this paper, we summarized habitat characteristics of the dry valley and reviewed the progress in ecological researches on plant adaptation, plant population, plant community, ecosystem and landscape in the region. In addition, as for current situation in management of the dry valley, we proposed particularly from perspective of plant ecology, expectations for further researches in this region. |
