It is a plant of the subclass Cinnamomum spp., Salix order, Salix family, and poplar genus, and is a deciduous medium-sized natural tree.

The diameter can reach meters, and the leaves are broad and fragrant. It is drought and waterlogg-resistant, tenacious in life, and is one of the rare tree species in nature.

The poplar tree can be up to 200 years old, with a straight trunk, 10-15 meters high, and sparsely shrub-like. The leaves are peculiar, because Yunqiao grows in the extremely arid desert area, in order to adapt to the arid environment of the bird, the leaves that grow on the young branches of the young trees are narrow and long like willows, and the leaves on the old branches of the big trees are round like poplars.

Ecological value. Populus euphratica is a precious forest resource unique to desert areas. Often grown in the desert, it is cold-resistant, drought-resistant, salinity-alkaline, sand-resistant, and has strong vitality. Poplar forest.

It is a unique precious forest resource in the desert area, its primary role is to prevent wind and fix sand, create a suitable oasis climate and form fertile soil, for thousands of years, Populus euphratica resolutely guarded in the border desert, watching the wind and sand.

Populus euphratica is also known as the "patron saint of the desert". Populus euphratica is essential for stabilizing the ecological balance of desert river zones.

It plays a very important role in windbreak and sand fixation, regulating the oasis climate and forming fertile forest soil. It is a natural barrier for the development of agriculture and animal husbandry in desert areas.

Maple poplar (pterocarya stenoptera) is a deciduous tree of the Juglans family, also known as hemp willow and centipede willow. It is distributed in the vast areas of Shaanxi, Henan and Jiangnan.

Populus euphratica can tolerate drought in the desert and has a strong tolerance for salinity. The roots of Populus euphratica can penetrate up to 10 meters underground to absorb water, and its cells also have a special function to be unharmed by alkaline water. Populus euphratica is the oldest poplar tree, having been on Earth for more than 60 million years.

It is 15-30 meters tall and can sprout seedlings from the roots. Populus euphratica grows rapidly in northwest China, it can block quicksand, green the environment, protect farmland, and is an important afforestation tree species in northwest China, mainly distributed in the southern part of Xinjiang, the western part of the Qaidam Basin, the Hexi Corridor and other places. Populus euphratica is a deciduous tree, an ancient tree species remnant of the third century, a plant specialized due to desertification, and its preciousness is as famous as ginkgo, and it is known as a living fossil.
