[Edit this paragraph] Geographical location

Horqin, Mongolian means famous shooter. Successive dynasties were one of the nomadic areas under the jurisdiction of Habutu Hasal, the second brother of Genghis Khan, located in the eastern part of Inner Mongolia, at the northwest end of Songliao Plain, including the whole Xing 'an League and a part of Tongliao City. Horqin grassland is adjacent to Xilin Gol grassland in the west and Hulunbeier grassland in the north, with a vast territory and rich resources. Most of the Horqin grassland has become agricultural land and some sandy land, also known as Horqin sandy land. Named after the ancient Mongolian Horqin tribe. It is located at 42 5' ~ 43 5' north latitude and117 30' ~123 30' east longitude. It is 250 ~ 650 meters above sea level and located in the triangle between the west bank of Xilamulun River and Laoha River. It is high in the west and low in the east, stretching for more than 400 kilometers and covering an area of about 42,300 square kilometers. It belongs to Kailu County, Horqin Left-wing Middle Banner, Horqin Left-wing Rear Banner, Naiman Banner, Hure Banner, Horqin Right-wing Middle Banner, Horqin Right-front Banner, Onniute Banner, Chifeng City, Aohan Banner and Fuxin Mongolian Autonomous County of Liaoning Province in China.

The climate of spring breeze is cold in winter and hot in summer. The average annual precipitation is 360mm, which varies greatly and is unevenly distributed during the year. Mainly concentrated in June-August, northwest wind in winter and southwest wind in spring and autumn. The annual average wind speed is 3.5m/s, the maximum wind speed can reach 2 1.7m/s, and the number of windy days often reaches about 30 days. Strong wind is an important factor in the formation and development of sandy land. The sunshine hours in the whole region are 2900 hours, and the sunshine rate is 67%. The active accumulated temperature above 10℃ is 3 160℃, and the frost-free period is 140 ~ 150 days.

Tuo and Dian coexist in Horqin grassland. Tuozidi refers to mobile, semi-mobile and semi-fixed sand dunes with a relative height of more than 2 meters. The soil is white sandy soil and yellow sandy soil, and the vegetation mainly includes Cryptomeria fortunei, reed, yellow willow and elm. ? Point refers to a relatively flat sandy land with a relative height of less than 2 meters. The soil is yellow sandy soil and chestnut sandy soil, and the vegetation mainly includes cryptospermum, Leymus chinensis and Agropyron cristatum. Dianzi land refers to the low wetland distributed between Tuodi and Dianzi land, which is mostly composed of all kinds of meadow soil. The vegetation is mainly composed of Leymus chinensis, inch grass moss, Sanguisorba officinalis, tiger grass and iris. Horqin Grassland Horqin Grassland used to be a land with many rivers and abundant water plants in history. According to records, in the 10 century, the natural conditions were "fertile land suitable for farming and aquatic plants convenient for animal husbandry". Until the beginning of19th century, a large area of grass vegetation and forests remained in most areas of Horqin. However, since the middle and late19th century, due to many factors, such as excessive reclamation, deforestation and immigration in the upper reaches of Liaohe River, the water sources in the lower reaches have been seriously damaged, and the ecological balance has been seriously damaged. The northern part of Chifeng, once known as the "800-mile pine forest", has now become a vast sandy land. Due to the unreasonable use of grassland by human beings, Dianzi land has been shrinking, the lump and land have been expanding, and the desertification area has increased sharply, eventually forming a large sandy land. The relative area of supporting electricity is 3∶ 1, which directly threatens the development of production and human life. In order to prevent desertification, grassland degradation and soil salinization, measures such as grassland enclosure, ploughing and replanting, artificial grass planting, flood diversion and siltation, prevention of overgrazing, and construction of shelter forest have been taken, and good results have been achieved. Horqin Grassland is a multi-ethnic area with Mongolian as the main body and Han, Manchu, Korean and so on.
