The official pasture in the northern frontier of the Qing Dynasty was a place where the Qing government concentrated on raising livestock on the basis of traditional animal husbandry activities. It was a common form of animal husbandry production and management by its administrative government and military government, and it was also a mature and advanced animal husbandry management institution and organization. The official pastures in Qing Dynasty are mainly divided into four parts or four categories: Taibusi Ranch, Royal Ranch (Shangyuan Ranch), Eight Banners Ranch and green camp Ranch. Taibusi Ranch run by the imperial court and Shangyuan Ranch run by the Ministry of Internal Affairs belong to the central ranch; Eight Banners Ranch and green camp Ranch belong to local military pastures. In the early years of Shunzhi, the imperial court set up a stallion farm outside Zhangjiakou and a Yuanma Temple in Shaanxi Province, all of which were subordinate to the Ministry of War. Later, in the fourth year of Kangxi (1665), Yuanma Temple was cut and the stallion farm was expanded. Five years later, the stallion farm was changed to Taibu Temple, and the left and right wing pastures of Chahar were set up separately. Taibu Temple Left-wing Ranch, located in Harranidun well outside Zhangjiakou, has a vast land, 6 miles in Fiona Fang; Right-wing ranch on the Kizilhan River, 4 miles from Fiona Fang. During the reign of Emperor Kangxi, the two-wing pasture * * * raised 16 herds of mules and horses, about 32, horses, and 32 herds of horses, each with 59-35 horses. In the early Qing Dynasty, the Imperial Horse Farm, which was established outside Dushikou and directly belonged to Shangyuan, was located in Shangdu, Daligang 'ai, Shangdu, Dabsunnuoer and other places, with lush water plants and a boundary stretching for more than a thousand miles. At first, there were three animal husbandry farms in Shangyuan, and then it was increased to five farms, namely, Ma Ying of Dalinghe Herd, Ma Ying of Yangyuhe Muhada Herd, Suluke Herd and Black Cattle Herd and Cattle Camp 1 of Yangyuhe Herd. In the forty-ninth year of Emperor Kangxi (171), the ranch owned by Shang's Courtyard raised 197 herds of mules and horses, 46 herds of horses, 2 herds of horses, 22 herds of camels, 2-5 horses in each herd, and 1-2 peaks in each herd. The Eight Banners Ranch, built in Chahar, is also a vast area in Fiona Fang, covering an area of thousands of miles in the east, to the border of Keshiketeng Banner, to the border of Tumote Banner in Guihua City in the west, to the edge of Tongfu and Shuoping Prefecture in the north of Shanxi Province in the south, and to the border of Su Nite and the four sub-ministries in the north. During the Shunzhi period, there were: Zhenghuangqi Ranch, Xianghuangqi Ranch, Zhengbaiqi Ranch, Xianghuangqi Ranch, Zhenghongqi Ranch, Zhenglanqi Ranch and Inlaid Lanqi Ranch. According to the statistics of forty-nine years of Kangxi, there are 95 herds of cattle and 18 herds of sheep in the pastures of Xianghuang Banner, Zhenghuang Banner and Zhengbai Banner. Cattle in a group of 12, * * * more than 3; Sheep in a group of 4, * * * 216, "3. When I arrived in Qianlong, I also set up Suiyuan Eight Banners Ranch behind Daqingshan, which was quite effective. In contrast, green camp Ranch was set up late and was formally established in the first year of Qianlong (1736). At first, it was because of the lack of military horses in the northwest, and the mediation was difficult. Therefore, Liu Yuyi, an official minister, in the twelfth year of Yongzheng (1734), when acting as the governor of Shaanxi and Gansu and handling military affairs, invited him to set up a pasture and raise military horses in the northwest to enrich the border defense. Emperor Yin Zhen approved Liu Yuyi's request to set up a pasture in each of the four military towns. Two years later, the earliest green camp pasture was built in Dacaotan of Ganzhou, Huangyangchuan of Liangzhou, Baiyang Rong of Xining and Paidai Lake of Huahaizi of Suzhou. Ten years later, another green camp ranch was built in Anxi County, Gansu Province. In the twenty-five and twenty-six years of Qianlong (176 and 1761), two pastures were established in Urumqi and Barkun, Xinjiang. A few years later, barkun ranch was divided into two fields: east and west. In addition, the Qing government also set up green camp horse farms in Jimusa, Gucheng, Manas and Talbahatai in Xinjiang. The above kinds of pastures are an embodiment of the rational utilization of natural resources by the Qing government according to its geographical characteristics.
