摘要
青藏高原的快速隆升,不仅改变了原有的地貌形态,而且还改变了构造格局、河流走向、亚洲季风和大气环流等。以全国生态地质环境遥感调查与监测成果为基础,从青藏高原隆升的角度出发,系统分析了高原生态地质环境特征、高原生态地质环境响应与规律。研究结果表明:青藏高原地质环境是控制青藏高原及其周边地区生态环境形成、发展与演化的基础;青藏高原的快速隆升为现代冰川发育、荒漠化、地质灾害等的发生提供了外力因素;青藏高原气候环境是我国生态环境变化的重要动力来源;人类活动对青藏高原及其周边地区起到了催化剂作用。
The rapid uplift of the Qinghai - Tibet Plateau has changed the morphologic units, the tectonic frameworks, the rivers strike, the Asian monsoon and the climate. On the basis of the survey and monitoring results of eco - geological environment and from the angle of the uplift of the Qinghai - Tibet Plateau, this paper systematically describes the eco - geological environment features, the response of eco - geological environment and its regularity in the Qinghai -Tibet Plateau. The results show that the geological environment of the Qinghai -Tibet Plateau is the foundation controlling the formation, development and evolution of ecological environment of the Qinghai - Tibet Plateau and its surrounding areas. The rapid uplift of the Qinghai - Tibet Plateau has provided external factors for modern glaciers, desertification and geological disasters. Besides, the climatic environment of the Qinghai -Tibet Plateau is the power source of ecological environment change in China. Human activities have played a catalytic role in ecological environment change in the Qinghai -Tibet Plateau and its surrounding areas.
