摘要
自2003年始开展的青藏高原生态地质环境遥感调查与监测项目已取得了阶段性的成果,本文就项目涉及到的第四纪基础地质与第四纪冰川遗迹、现代冰川雪线、湖泊湿地、荒漠化等专题成果进行了简要介绍。本文明确了项目开展的意义,给出了青藏高原生态地质环境质量的评价结果,强调了地学因素对于青藏高原生态地质环境形成与演化的控制作用,以及近30 a来全球气候变化对高原生态地质环境适应性变化的驱动作用。
The project of Remote Sensing Survey of Ecology, Geology and Environment in Qinghai -Tibet Plateau beginning in 2003 has made some achievements. Surveying results of some sub - projects such as Quaternary geology and Quaternary glaciers, modern glaciers, lakes, wetlands （except for lakes） and desertification are discussed in this paper. The importance of this project to the environmental protection of Qinghai - Tibet Plateau is emphasized, and the assessment results of environmental quality of the plateau are recounted. Geological factors have played a long- term role in the formation of environmental heterogeneity in the plateau, and controlled its evolution in the geological history. In the past 30 years, the global climate change and human activities have resulted in some adverse effects on the environmental factors and even the sustainable development of China.
