摘要
岷江上游干旱河谷区地处青藏高原和四川盆地的过渡带上。它的自然环境非常复杂,生态系统较为脆弱,经济发展非常落后,社会文化多彩多样。由于恶劣的自然环境和过度的人类干扰,导致区域植被退化,引起了生物多样性丧失等一系列生态环境问题,对整个岷江流域乃至长江上游的生态安全和区域的可持续发展均构成严重威胁。因此,该地区的生态恢复和治理成了当前生态界关注的热点。本文详细阐述了该区域生态环境的现状及成因,并提出了科学的恢复对策。本项研究对区域植被恢复和改善生态环境具有重要的理论与实际意义。
The dry valleys in the upper reaches of the Minjiang River are located in the transition zone be- tween the Qinghai -Tibet Plateau and the Sichuan Basin. They have complex natural environments, vul- nerable ecosystem, backward economic development, and diverse social cultures. Because of adverse natu- ral environments and human interference, their original ecological environment becomes worse and worse, and brings about a series of ecological environmental problems, for example, vegetation degradation, and loss of biodiversity. In this paper, a detailed description is given of the present situation and reasons, and some scientific measures are put forward for the recovery of their ecological environment. This study has important theoretical and practical significance on the regional vegetation restoration and the improvement of ecological environments.
