Land resources Land resources are relatively vast, with a total area of 13 19.5 square kilometers. Ziwuling forest area in the east is a natural secondary forest area, covering 387 square kilometers, accounting for 29.3% of the total land area. There are dense forests, lush vegetation and superior vegetation here. It is a natural reservoir for water conservation and rainfall regulation in this county. It accounts for 80% of the total forestland area in our county. Most of the cultivated land is distributed in the relatively flat and fertile areas of Gonghe, Yonghe, Shanjia and Yueming.

The average ditch density is 0.67km/km2, and the ditch cut is between 150-200m. These gullies are seriously eroded, which is the main cause of soil erosion.

Due to the gentle terrain and the influence of summer monsoon, the climatic factors are relatively gentle. Ziwuling forest area has humid climate, low temperature, more rain and fog, less sunshine and long frost period. Form a special rain circle around the forest area. Due to the difference of monsoon intensity and advance and retreat, the annual and monthly distribution of rainfall is unstable. Generally, there is more precipitation in July, August and September, and spring drought is more frequent. The average annual sunshine hours in the county are 2447.4 hours. The diurnal range is good, which is beneficial to the growth of grain and cash crops. The frost-free period is longer, the temperature is higher, the sunshine is sufficient, and the rainfall is sufficient. The solar radiation problem, the sunshine hours are higher than those in the North China Plain at the same latitude, which belongs to one of the high-value areas of radiation energy in China and has great potential for light energy utilization. Because of the large daily temperature difference and high accumulated temperature, it is beneficial to photosynthesis, dry matter formation and sugar accumulation. The mechanical equivalent of rainwater and heat is basically synchronous, which is a superior condition for developing agricultural production. The average annual precipitation of water resources in the county is 623.5 mm, and the total annual precipitation is 85 1 100 million cubic meters. Five rivers belong to the Jinghe River system, among which Silang River is the largest, with a total length of 83 kilometers and a drainage area of 644 square kilometers, accounting for 47% of the county's total area, with an annual average flow of 0.9 1 sec cubic meter and a runoff of 28.8 million cubic meters.

[Edit this paragraph] The historical evolution was in ancient times (2 1 century ago), and Zhengning County was one of the places where the ancestors of Chinese culture, the Yellow Emperor Xuanyuan and Xiongshi clans, thrived. Xia dynasty (2070- 1600). The world is divided into Kyushu, and Zhengning belongs to the land of Yongzhou Xirong. During the Kongjia period of Xia Dynasty (about17th century BC), the ancestors of Zhou Dynasty did not rush to Qingyang and established the Northern Dog Country, and Zhengning belonged to the Northern Dog Country. In Xia Jie (late Qing Dynasty), Gong Liu, the ancestor of the Zhou Dynasty, moved his capital to Gongliucheng from the north, and formally established the first country of the Zhou Dynasty-Gong Liuguo. In Shang Dynasty (former 1600- former 1046), Zhengning was still under the jurisdiction of Xi 'an State. At the end of Shang Dynasty, the Zhou family moved to Qishan south, and the land was occupied by the Rong family of Yiqu, and Zhengning belonged to Yiqu. During the Western Zhou Dynasty (1046-77 1), the Rong State of Yiqu belonged to the Fang State under the jurisdiction of the Zhou Dynasty, and Zhengning still belonged to it. During the Spring and Autumn Period and the Warring States Period (770 BC-2265438 BC+0 BC), the old system was still adopted. In the first 400 years, Wei occupied Heshangjun County in Xihe County and built the Great Wall in Zhengning. Since then, the land in the eastern part of the Great Wall (now Zhengning Yongzheng, He Shan, Qitou and Sanjiadong) has been under the jurisdiction of Shang Jun County of Wei State, and the land in the western part of the Great Wall (west of Yulinzi and Luochuan) has been under the jurisdiction of Guo Rong. In the first 352 years, the State of Qin sent troops to attack the State of Wei and occupied the Xihe monk army in one fell swoop. Since then, the eastern part of Zhengning has been under the jurisdiction of Shang Jun of Qin, while the western part is still under the jurisdiction of Guo Rong of Yiqu. In the first 270 years, Qin destroyed Rong Yi and established Beidi County, the county site was changed to Yi. Since then, Zhengning has been divided into Beidi County in the west and Shang Jun County in the east. 22 1 year before Qin dynasty (22 1-206), after Qin Shihuang unified the whole country, the county system was established. Qin established three counties in Beidi County: Yulong (now Qingcheng County), Ningxian County (now Ningxian County) and Chaonan County (now Northwest zhenyuan county).
