China News Service, Tibet, Ali, August 12 (Reporter Sun Zifa) China's second Qinghai-Tibet Plateau Comprehensive Scientific Expedition Research (Qinghai-Tibet Scientific Expedition) team "History of Human Activities and Its Influence", which is carrying out the 2022 summer scientific expedition mission, recently visited The Ali Desert Environment Comprehensive Observation and Research Station of the Qinghai-Tibet Plateau Research Institute of the Chinese Academy of Sciences (the Ali Station of the Qinghai-Tibet Plateau Institute of the Chinese Academy of Sciences), had a discussion with the researchers of the Ali Station.
How does Ali Station help the Qinghai-Tibet scientific expedition?
Zhao Huabiao, the head of the Ali Station of the Institute of Qinghai-Tibet Plateau of the Chinese Academy of Sciences, said that since the launch of the second Qinghai-Tibet scientific expedition, the station has contributed to the scientific expeditions, and has become one of the "Western Wind-Monsoon Coordination and Its Influence", "Asian Water Tower Dynamic Change and Influence". Scientific expedition teams with multi-tasks and different topics such as Ecosystem and Ecological Security, Biodiversity Conservation and Sustainable Utilization, Human Activities and Living Environment Security, etc., provide multiple rounds of logistical conditions guarantee and observation data support.

He introduced that the Ali Station was built in 2008 and covers an area of 2 hectares. It is located in Ritu County, Ali Prefecture, Tibet, adjacent to Pangong Lake and about 1,600 kilometers away from Lhasa City.
The area where the station is located is a plateau sub-frigid monsoon arid climate zone, which has the characteristics of strong solar radiation, less precipitation, low temperature, large annual temperature difference, and strong wind in winter and spring. Concentrated development areas, important river source areas and lake distribution areas, the "roof" of the "roof of the world", and fragile alpine desert ecosystems.
The observation content of Ali Station includes atmospheric physics, atmospheric environment, glacier change, river hydrology, lake hydrology, and ecosystem. Under the influence of the cryospheric water cycle and changes in the alpine desert environment, build an observation and research demonstration base that integrates comprehensive observation, logistical support, scientific research, and ecological protection.
Its scientific goals include: monitoring and studying changes in climate, hydrology, atmospheric environment and ecological processes in the western Qinghai-Tibet Plateau, revealing the synergistic process and impact of the Indian monsoon and westerly wind, and predicting future climate and environmental changes, providing research for global change and the western region of the Qinghai-Tibet Plateau. Provide scientific support for social and economic development and ecological environment security.

Zhao Huabiao pointed out that after more than 10 years of active construction, Ali Station has now become one of the 17 main field stations in China's "Alpine Surface Process and Environmental Monitoring and Research Network", filling the gap in observation in the western part of the Qinghai-Tibet Plateau.
He revealed that in the future, Ali Station will continue to support major projects such as the second Qinghai-Tibet scientific expedition, "Pan-Third Pole Environmental Change and Green Silk Road Construction", "Qinghai-Tibet Plateau Earth System Basic Science Center", as well as various scientific research institutions. The research project provides the required observation platform, data support and logistical support.
It is understood that since the establishment of the Institute of Qinghai-Tibet Plateau of the Chinese Academy of Sciences in 2003, the long-term observation of field stations has been determined as the foundation of the institute.
In 2005, the institute started the first batch of three field stations: "Namtso Multi-Circle Comprehensive Observation and Research Station", "Qomolangma Atmospheric and Environmental Comprehensive Observation and Research Station", and "Southeastern Tibet Alpine Environment Comprehensive Observation Station". Gexi Wind Belt Environmental Comprehensive Observation and Research Station" and "Nali Desert Environmental Comprehensive Observation and Research Station"; in 2010, the Nagqu Station was built in cooperation with Tibet University; in 2016, the "Medog Earth Landscape and Earth System Comprehensive Observation and Research Center" was established. A field scientific observation and research system consisting of 7 stations (centers) and multiple independent observation points has been established with the Lhasa Ministry as the support and coordination center and the National Qinghai-Tibet Plateau Scientific Data Center as the core. So far, a large amount of first-hand observation data has been obtained. It has provided strong support for major national scientific research tasks and served local economic and social development, and has become an important scientific experiment and popular science education base in the Qinghai-Tibet Plateau.
