Which province is the loess high slope mainly located in?

Loess high slopes are mainly distributed in Shaanxi Province.

The high loess slope is the loess plateau. From the perspective of provinces, the Loess Plateau spans seven provinces: Shanxi, Shaanxi, Henan, Inner Mongolia, Ningxia Hui Autonomous Region, Gansu and Qinghai. It is one of the four plateaus in China, with vast landforms, but serious soil erosion, broken terrain and fragile ecological environment.

It not only belongs to one province, but spans several provinces. Loess high slope is one of the regions with the most serious soil erosion and the most fragile ecological environment in the world. The terrain slopes from northwest to southeast. Except for many rocky mountains, most of them are covered with thick loess. After a long period of intense erosion by flowing water, it gradually formed a special natural landscape with thousands of valleys and broken terrain.

Scale of loess high slope:

The Loess Plateau is 1000 km long from east to west and 750 km wide from north to south, including the vast areas west of Taihang Mountain, east of Sun Moon Mountain in Qinghai Province, north of Qinling Mountain and south of the Great Wall. It is located on the second step of China, with an altitude of 800-3000m. The Loess Plateau belongs to the continental monsoon climate of warm temperate zone.

Tectonic units mainly include Longdong platform, Hualixi fold belt, Pacific Yanshan fold belt, Longxi block, Zhongtiaoshan block, Luliangshan block and settlement belt in the lower reaches of Wei Fen. Qinling axis and Ordos platform are the two major dividing lines between north and south.

The Loess Plateau is an important energy and chemical base in China. Loess has fine particles, soft soil and rich mineral nutrition, which is beneficial to farming. Basin and valley agriculture has a long history. Except for a few rocky mountains, the thickness of loess is between 50 and 80 meters, and the maximum thickness is 150 ~ 180 meters.
