The role of the development of solar energy resources in Heihe River Basin in protecting local vegetation

The development of solar energy resources in Heihe River Basin plays an important role in protecting local vegetation, providing a balanced, high-quality and effective supplement to the local power grid, and at the same time, making due contributions to the company's implementation of the national "double carbon" goal with practical actions.

Heihe river basin is the second largest inland river basin in northwest China, located in the middle of Hexi Corridor, roughly between 98-11 3 ′ E and 38-42 N, and it is the largest inland river basin in western Kan Moun. Heihe river basin is located in the middle of Eurasia, far away from the ocean and surrounded by mountains. The climate of the basin is mainly influenced by the circulation control of westerlies at middle and high latitudes and polar cold air masses. The climate is dry, with sparse and concentrated precipitation, strong winds, abundant sunshine, strong solar radiation and large temperature difference between day and night.

the Heihe river is 821 kilometers from its birthplace to Juyanhai, spanning three different natural environment units, with a drainage area of about 142,9 square kilometers. It borders Mongolia in the north, the Great Huangshan Mountain in the east and the Shule River Basin in the west. It belongs to three provinces (regions), with Qilian County in Qinghai Province in the upper reaches, Shandan, Minle, Zhangye, Linze, Gaotai, Sunan and Jiuquan in Gansu Province in the middle reaches, and Jinta in Gansu Province and Ejina Banner in Inner Mongolia Autonomous Region in the lower reaches.

Geographical environment:

Heihe River originates from Qilian Mountain in the south, and it is divided into two branches: the east branch is the main stream, and the upstream branch is divided into two branches. The east branch of Ebo River, also known as Babao River, originates from Jinyangling in the east of Ebo Beach, and flows from east to west for more than 8 kilometers. The west branch of Yeniugou, which originates from Tieligan Mountain, flows from west to east for more than 19 kilometers, and the east and west branches converge at Huangzang Temple to flow north, which is called Gan.

The west branch originates from Taole Temple, and the upper reaches are called Taolai River. There are also east and west branches that meet near Zhu Long Temple and are called Beida River (or Linshui River). Heihe River enters Hexi Corridor from Yingluo Gorge, near the northwest of Zhangye City, flows to the northwest through Nashandan River and Hongshui River, crosses Zhengyi Gorge (Beishan) through Linze, Gaotai Huiliyuan River and Bailang River, and enters Alashan Plain. The flow from Yingluo Gorge to Zhengyi Gorge is 185 kilometers, with an average river bed gradient of 2‰, which is the middle reaches of Heihe River (the main stream).

After the Heihe River flows through Zhengyi Gorge, Dingxin in Jinta County, Gansu Province joins Beida River, flows 15 kilometers north to the western foot of Langxin Mountain in Ejina Banner, Inner Mongolia Autonomous Region, and is divided into two rivers, the East River (Darcy Aobao River) is divided into eight tributaries (Nalin River, Baoduge River, Angzi River, etc.) to the north and flows into the East Juyan Sea (Suponaoer) in a fan shape. The Xihe River (Mulin River) is divided into five tributaries (Gongzi River, Kelidu River, Matigege River, etc.) to the north and flows into the West Juyan Sea (Gashunnaoer).
