基于野外站网络的青藏高原地表过程观测研究

 由于地形地貌的复杂性，国际对青藏高原及其邻近地区的地表过程观测研究持续关注，中国高寒区地表过程与环境观测研究网络也逐渐形成。整合了中国科学院的17个野外观测站，针对中国高寒区特有的大气、冰川、冻土、湖泊、高寒生态系统等地表过程开展长期观测。通过推动建立规范的观测指标体系，逐渐统一观测仪器设施，开展数据集成与共享等，野外站的观测研究能力得到显著提升，产出了一批具有国际影响力的高水平科研成果，如发现青藏高原降水具有西风、季风和二者过渡区3大模态等，为区域经济社会发展的决策提供了科学依据。未来，野外观测站会统筹长期观测与有限目标的关系，建设高寒网科学数据平台，更好地服务和支撑国家重大科技任务和战略需求。

Observations of land surface processes of the Tibetan Plateau based on the field stations network

Due to the complexity of topography and geomorphology, the worldwide research focus is now on the surface processes of the Qinghai Tibet Plateau and its adjacent areas. The High-cold Region Observation and Research Network for Land Surface Processes & Environment of China (HORN) has gradually formed. It integrates 17 stations of Chinese Academy of Sciences, for long term observations and researches of the land surface processes, including glaciers, permafrost, lakes, alpine ecosystem in the high-cold regions of China. Through the construction of the standard observation index system, the coordination of the observation instruments, the integration and the sharing of the observation data, the HORN has significantly promoted the station-level observation abilities, and played important supporting roles in the studies of the earth system, the resources and the environment sciences on the Tibetan Plateau. Some scientific results of international level have been achieved based upon the station observation data, e.g., it was found that the precipitation of the Tibetan Plateau has 3 modes, the westerly wind, the monsoon and their transition zone. These data has also provided reliable scientific basis for the decision-making of the regional economic and social development. In the future, the field observation station will co-ordinate the long-term observation and the limited objectives, and construct the alpine network of scientific data platform to better serve and support the country's major scientific and technological tasks and strategic needs.
