全球气候变化背景下祁连山生态问题的地质学探析

祁连山生态问题产生的根源主要在于全球气候变化背景下冰川、冻土、植被、径流等及其水文循环的变化.该文以地球系统科学为指导,在宏观尺度上从系统演化的角度去探讨在全球气候变化条件下祁连山生态问题,认为这些问题的产生与地质过程密不可分,应以生态地质学的理论来研究这些变化的生态地质过程,并指出未来进行祁连山生态问题研究的科学路径,为祁连山的生态保护、河西走廊社会经济的持续健康发展提供科学依据.

Exploration of Ecological Problems of Qilian Mountains under the Global Climate Changes on Geology

The origin of ecological problems of Qilian Mountains mainly lies in the changes of glacier ,frozen soil, vegetation, run-off and hydrological cycle under global climate changes. Under the guidance of earth system science, this paper from the point of system evolution explored ecological problems of Qilian Mountains under the global climate change conditions on a macro scale. These problems are inseparable with geological processes, by using the ecological geology theory to study the changeable ecological process. This paper points out the scientific path to study Qilian Mountains geology problems, and provides scientific basis for the ecological protection of Qilian Mountains and social and economic sustainable de- velopment of Hexi Corridor. 18refs.
