Chinese scientists draw high-precision grass vegetation maps on the Qinghai-Tibet Plateau and use AI to overcome identification problems – Passionategeekz

Passionategeekz On June 18, according to Xinhua News Agency, at the academic seminar on grass vegetation map of the Qinghai-Tibet Plateau held on June 17, the Qinghai-Tibet Plateau grass vegetation group map drawn by Professor Wang Yanfen of the University of Chinese Academy of Sciences was officially released.This is the most accurate vegetation map of the Qinghai-Tibet Plateau grassland in my country.carefully depicts the spatial distribution pattern of 65 plant groups or group groups.

Wang Yanfen introduced that the Qinghai-Tibet Plateau is the roof of the world and the water tower in Asia, and is an important ecological security barrier in my country. The Qinghai-Tibet Plateau ecosystem is mainly grasslands and belongs to global climate change-sensitive areas and ecologically vulnerable areas.In the past 40 years, the grass vegetation on the Qinghai-Tibet Plateau has undergone significant changes, and the original grass vegetation map is difficult to accurately reflect the current plant community structure and function.。

The scale of the grass vegetation map released this time is 1:500,000. During the drawing process,The team uses artificial intelligence technology in deptheffectively digging and integrating multi-dimensional information from tens of thousands of field survey samples and hundreds of remote sensing layers, overcome the difficulties of accurate identification and classification in complex plateau environments, and clearly demonstrate the spatial characteristics of the grassland plant community structure based on groups.

Passionategeekz learned from the report thatThe team identified 65 plant groups or group groupsAmong them, the five groups are the most widely distributed, including alpine meadow, purple-flowered meadow, dwarf meadow, dwarf meadow, dwarf meadow and thread-leaf meadow.

Several experts attending the seminar said that this grassland vegetation map not only accurately depicts the spatial distribution of flora, but also explains the impact of plant carbon input quantity and quality on the stability of soil carbon pools.It is of great significance to better carry out research on the Qinghai-Tibet Plateau ecosystem。
