Nature · Xinjiang ⑤ 丨 Forest Ecology "Observer" on the Tianshan Mountains -Plums Tower

Reporter Cao Hua

In the depths of the Tianshan Mountains surrounded by mountains, a 75 -meter -high silver -white tower stands in the forest, stretching straight to the sky, as if it is higher than the surrounding Snow Lingyun.

This high tower is the general volume tower of Xinjiang Xitian Mountain Forest Ecosystems in Xinjiang Xitianshan Forest Ecosystem in Xinjiang Xitian Mountain National Nature Reserve, which is located in the mountains of 1694 meters above sea level. The flux tower has two operating platforms: 50 meters and 70 meters. It is equipped with a variety of observation equipment such as carbon dioxide, water vapor analyzer and ultrasonic wind speed instrument. Various elements such as volume, carbon dioxide and water vapor concentration have the most comprehensive indicators in Xinjiang. Observation equipment is located in the leading ranks in China, filling the gap of the forest general positioning observations in Xinjiang. Important platform for work.

It is understood that forest flux observation is based on the technology of micro -weather science as the main means, and conducts long -term observation and research on forest ecosystems and atmospheric CO2, water vapor and energy flux, which can provide forest carbon exchange and dual carbon targets Basic data, and then analyze and evaluate the carbon balance and ecological service functions of the forest ecosystem. In ground observations, the flux tower is the most direct and effective, and relatively accurate observation means to measure the carbon exchange capacity of the land ecosystem. At present, there are nearly a hundred flux tower in my country, which is distributed in the national land ecology. In all parts of the system, just like a listener installed on the land, the changes in the ecosystem of the veins anytime, anywhere provide scientific data support for ecological environmental protection decisions.

Xinjiang Xitian Mountain Forest Ecosystem National Positioning Observation Research Station was established in 2013. It was officially operated in 2015. It is the first site in Xinjiang to conduct forest flux positioning observations. 1 meteorological station and 3 surface runoff fields can be carried out in the forest area conventional meteorological observation, forest climate observation and carbon dioxide, water vapor, soil heat flux observation, surface runoff observation and other observation items. At present, the forest flux tower of the station has accumulated billions of effective observation data. Researchers at the station conducted a preliminary analysis of the carbon flux and forest climate on the Xueling Yunshan Forest Ecosystem. Nine papers such as comparative studies have obtained two software copyrights such as "Xinjiang Tian Shan Shan Shan Shan Shan System Positioning Monitoring Big Data Cloud Management Platform". The National Positioning Observation Research Station of Xitian Mountain Forest Ecosystem in Xinjiang has also received licenses such as the “National Forest Cao Ecological Comprehensive Monitoring Station” and “National Charity Forest Ecological Evidence Monitoring Station”.
