The west is located in the middle part of Taihang Mountain, including Jingxing County and jingxing mining area, and the mountainous areas of Pingshan, Zanhuang, Xingtang, Lingshou, Luquan and Yuanshi County, accounting for about 50% of the city's total area. The eastern part is the plain part formed by the flood of Hutuo River. Pingshan to the west slope of Shijiazhuang is11400-11200, and Shijiazhuang to the east slope of Xinji is11200. The geotectonics in the area under its jurisdiction belong to the marginal zone of Shanxi platform and Bohai depression, with low topography in the east and high topography in the west. Taihang Mountain in the west is about 1000 meters above sea level, with overlapping mountains and towering terrain. East of Beijing-Guangzhou Railway is a part of North China Plain. From west to east, the landforms are Zhongshan, low mountains, hills, basins and plains in turn. Camel beam, the highest peak in Pingshan, is 228 1 m above sea level, which is the fifth peak in Hebei Province and the commanding height of Shijiazhuang. According to the origin, the eastern plain belongs to the piedmont alluvial plain of Taihang Mountain, with an altitude of 30- 100 meters, of which Pompeii village in xinji city is 28 meters above sea level, which is the lowest point in the jurisdiction. (The following data are provided by the Municipal Planning Bureau) The terrain in the Second Ring Road of the urban area is high in the northwest and low in the southeast, with the northwest corner at an altitude of 8 1.5m and the southeast corner at an altitude of 64.3m. Shijiazhuang city is located in the eastern edge of mid-latitude Eurasia and belongs to the continental monsoon climate of warm temperate zone. The seasonal variation of solar radiation is remarkable, with frequent high and low pressure activities on the ground, distinct four seasons, disparity between cold and hot, concentrated rainfall, obvious dry and wet cycles, long summer and winter, and short spring and autumn. It takes about 55 days in spring, 0/05 days in summer, 60 days in autumn and 0/45 days in winter. In spring, the climate is dry, with little precipitation, and there are often northerly or southerly winds of grades 5 and 6, and the temperature rises rapidly in April; In summer, due to the influence of ocean temperature and humidity airflow, the precipitation in June, July and August accounts for 63%-70% of the annual precipitation; Influenced by Mongolian high pressure in autumn, it is sunny and rainy, with moderate temperature and pleasant climate. Late autumn, more northeast wind, cold wave. In winter, influenced by Siberian cold high, northwest wind prevails, the climate is cold and dry, the weather is sunny and cloudy, and there is little precipitation. The general climate characteristics of Shijiazhuang are: high annual average temperature, high temperature in spring and summer, cool in autumn, cold in winter, uneven rainfall distribution, almost all the year round in most areas, more rainfall in some mountainous areas in the west, floods, less sunshine, and more windy and windy weather in spring. The total precipitation is 40 1. 1-752.0mm, which is unevenly distributed in time and space. Among them, the rainfall in the western mountainous area is 628.4-752.0 mm; Other areas are 401.1-595.9mm. There is more snowfall in winter, and the total snowfall is10.0-19.2mm. Among them, the snowfall in urban areas is19.2mm. Heavy snow has brought a lot of inconvenience to people's traffic. At the same time, it plays a protective role for winter wheat and provides favorable water conditions for turning green in spring. There is little precipitation in spring, and the total seasonal rainfall is11.0-41.7mm. The summer rainfall is unevenly distributed, and the seasonal rainfall is145.2-516.4mm. The total annual sunshine hours are1. The rivers within the jurisdiction of Shijiazhuang belong to the Daqinghe River System and Ziya River System in Haihe River Basin. There are 6 main flood channels, of which Shahe and Cihe wood road Gully in the north belong to Daqing River system. Hutuo River, Hutuo River, Huaihe River and Zhenjiang River in the south-central part belong to Ziya River system. The total drainage area is 33,500 square kilometers. There are many tributaries in the upper reaches of the river and the vegetation coverage rate is low. In addition, the source is short and the flow is urgent, which shows that the flood rises and falls sharply. After the river entered the plain, it was shallow and curved, so it changed its course frequently before the founding of the People's Republic of China. After the founding of People's Republic of China (PRC), under the leadership of the Party and the government, a control backbone flood control project was built in the upper reaches of the river, and more than 500 kilometers of dikes were repaired and reinforced in the lower reaches, which significantly improved the flood control and disaster resistance. Hutuo River: It is one of the two tributaries of Ziya River system. Originated at the northern foot of Wutai Mountain in Fan Shi, Shanxi Province, it passes through Ding Xin Basin, passes through Taihang Mountain, and enters Pingshan in Shijiazhuang City from Zhuang Yan in Yuxian County. Near Huangbizhuang, Luquan City, a large tributary smelting river enters it, crosses the suburb, Zhengding, Gaocheng, Jinzhou and Wuji borders eastward, leaves Shenze and enters Anping County, Hengshui City. Hutuo River is 20 1 km in Shijiazhuang, which is the largest spillway in Shijiazhuang. The flood control standard is once every 50 years, and the design flow is 3300 cubic meters per second. The north embankment of Hutuo River is a key flood control project in this province. There are two large reservoirs, Gangnan Reservoir and Huangbizhuang Reservoir, in the main stream of the upper reaches of Hutuo River, and two medium-sized reservoirs, Shiban Reservoir and Xiaguan Reservoir, are built in the tributaries of Duwen River and Nandian River respectively. Yanhe River: Originated in the mountainous area in the southern suburbs of Luquan City, Huijin River and Shijiazhuang flood discharge canals entered Luancheng County, then merged with Beishahe River and Weihe River, and entered Ningjin County of Xingtai City through Zhao County. The Yanhe River in Shijiazhuang, with a total length of 48 kilometers, is the main flood discharge channel in Shijiazhuang and one of the main drainage projects in the city. The flood control standard below Beijing-Guangzhou Railway is 12 years, the water volume is 665 cubic meters per second, the drainage standard is once every three years, and the maximum flow is 178 cubic meters per second. Its tributary Zhulong River has a medium-sized reservoir, Bayi Reservoir. Huaihe River: Zhangshiyan, which originated in the southwest of Zanhuang County, passes through Zanhuang County and enters Ningjin County of Xingtai via Yuanshi County, Gaoyi County and Zhao County, with a total length of 79 kilometers.

The south undercurrent in Tang Dynasty was called Cihe River and wood road Gully. The river planning standard is once every 20 years, and the flood discharge is 1260 cubic meters per second. There is a large reservoir upstream, Hengshan Reservoir.
