The history of Huihe River

In ancient times, Huihe was called Grey River, Hunhe River and Luoshui, and Hanshu was called water control. Hui River originated at the foot of the watershed mountain in Zhuangxiang, with a length of 32km in ningwu county and a drainage area of 30 1 km2. It flows northward near the ants in Shuozhou and joins the Ziyuan River, which originated in Xinzibao Village, Zuoyun County, and becomes the Sanggan River. Hui River is the third largest river in ningwu county, and its flow is second only to Fenhe River and Honghe River, but its status and influence are second only to Fenhe River. Because this is the upper reaches of Sanggan River and the source of Yongding River in Beijing. "He Hui Fu Liu" has been one of the eight scenic spots in Ningwu since ancient times. When it flows through Jiuniukou of Yangfangkou Fort, it becomes the only flood and drought artery in China. The towing platform flowing through it has been an important military fortress since ancient times. Yang Ye, a famous enemy guard in Song Dynasty, was martyred in Chenjiagu near Tuoliantai. It can be said that the rise and fall of Uighur is closely related to Sanggan River and Yongding River, and the history of Uighur is also the history of Han nationality's indomitable resistance to foreign aggression. It is with its broad mind, marriage, trading, communication, integration and reference, and jointly create the history of human civilization; That is, the farming culture in the Central Plains and the nomadic culture in Mobei influenced and infiltrated each other, and jointly created the history of Chinese civilization. Therefore, Uighur culture is magical, long-standing, magnificent and profound. There have been countless exchanges and struggles in history, brutal wars have been staged here, countless tit-for-tat negotiations have been held here, and people's spontaneous alien and pro-trade, migration and trade have developed here. Not Sanjin mother river, but also Sanjin parents river.

The Records of Shuozhou in the Qing Dynasty recorded: "Huihe River flows for fifty miles, leaving Ningwu Junguan, reaching Hongyaer Village 15, reaching the south of Tayi Village, passing through the south of the city to Mayi, reaching Sangqian River and reaching Nanhe."

Jiuniukou refers to the nine-hole bridge built on the Yangfangkou after the Uighur River passes through it, in order to connect the Yangfangkou Fort and the Ningwu Military Port to support the Lotus Platform. The flowing water under the bridge and the Great Wall building on the bridge are very spectacular, which is a great spectacle of the ancient China. It embodies the outstanding architectural technology and superb wisdom of our ancestors. Therefore, Ning Wuguan has become the only flood and drought barrier in China.

(Records of Shuozhou) It is recorded that the camel joint platform is on the western hill of Yangfangkou. "Ningwu County Records" records: "Torotai is in Ningwu Guandong. Today, the mountain to the west of Yangfangkou is called Camel Lotus Platform. Relying on the natural barrier of Huihe River, the camel is commanding, easy to defend but difficult to attack, which is the throat of Ning Wuguan out of Mobei. Since ancient times, it has been suitable for human activities because of its leeward and sunny, open and easy to defend but difficult to attack, and gurgling springs. Traces of ancient human activities can be seen everywhere here, such as sand-sandwiched pottery pieces in Shang and Zhou Dynasties and even in the Spring and Autumn Period and the Warring States Period. Yang Ye, a famous enemy in Song Dynasty, died in Chenjiagu nearby, making Liantai famous in history. Only Taiyi River has the value of existence, and this river also shows its tragic.

According to the Historical Changes and Natural Disasters of Taihang Mountain Forests compiled by the Ministry of Forestry, there used to be dense temperate summer green forests in Huihe River Basin in China, and coniferous forests such as fir, spruce and larch were found in mountainous areas above 1500m. From 1000 m to 1500 m, there are mixed forests of Platycladus orientalis and Pinus. When describing Yanbei area, Li Daoyuan's Notes on Water Mirror in the Northern Wei Dynasty wrote: "Mountains and trees span several counties, Wan Li forest sets, and Maolin falls". During the Liao, Yuan and Ming Dynasties, the forests in Huihe River Basin were cut down and destroyed on a large scale. After the Qing Emperor Kangxi, with the immigration and other factors, the population increased, the forest was continuously destroyed, the cultivated land was continuously expanded, and the forest vegetation was completely destroyed. This has led to the situation of "natural hazards closing the mountain and worrying about the ravine" and "no trees and no birds in the wild".
