Chaoyang City is located in the west of Liaoning Province. Its jurisdiction is between 118 ° 50 ′ e to 121 ° 17 ′ E and 40 ° 25 ′ n to 42 ° 22 ′ n. the East-West span is about 165 km, the North-South span is about 216 km, and the boundary perimeter is about 980 km. It borders Chifeng and Tongliao in the north, Huludao in Liaoning Province and Qinhuangdao in Hebei Province in the south, Fuxin and Jinzhou in Liaoning Province in the East and Chengde and Qinhuangdao in Hebei Province in the West. The total area is 19736 square kilometers.
Chaoyang City is located in the transition zone from Inner Mongolia Plateau to coastal plain, which belongs to mountainous and hilly area. Chaoyang City is characterized by low mountains and hills. The terrain is higher in the north, northwest and southwest, and lower in the East, which is like a dustpan opening to the East. According to the geomorphological origin and morphological characteristics, Chaoyang City can be divided into four topographic units: the central and western low mountain area, the eastern low mountain and hilly area, the river alluvial plain, and the Intermountain basin. In Chaoyang City, Songling mountain and Nuluerhu mountain run through the whole area in Northeast southwest direction, with alluvial plain and Intermountain basin between them.
Chaoyang is located in the north temperate continental monsoon climate zone. Although the southeast is affected by the warm and humid ocean, due to the frequent invasion of dry and cold air in the northern Mongolian Plateau, a semi dry and semi humid area is formed, with four distinct seasons, hot and rainy seasons, sufficient sunshine, large daily temperature difference and less precipitation. The annual average temperature is 5.4 ℃ - 8.7 ℃; the average annual sunshine hours are 2850-2950 hours; the annual precipitation is 450-580mm; the frost free period is 120-155 days. In spring and autumn, it is windy and prone to drought. The wind force is generally 2-3. The temperature is higher in summer, and the northwest wind is prevailing in winter.
There are 47 large and small rivers in Chaoyang City, with a total length of about 2278 kilometers. Among them, there are 5 rivers with a drainage area of more than 1000 square kilometers, namely Daling River, Xiaoling River, Qinglong River, Liugu River and Laoha River, with 42 tributaries. There are water systems in all the six counties (cities), among which Chaoyang and Beipiao have developed water systems and formed broad zonal plain by alluvial. Most of the rivers in other counties are tributaries with small water flow.
There are three basic characteristics of rivers in Chaoyang City: due to the small precipitation, the river runoff is not abundant. Under normal conditions, except summer and autumn, the water filling capacity of the river is not large. The river surface is narrow and the depth of water is small, often showing intermittent state. Except Laoha River, the other four rivers flow from west to east to Southeast or straight south. The riverbed is steep. There are mountains and rocks in the upper reaches of the river. The river is narrow and has a large drop, resulting in a strong cutting on the terrain. The middle and lower reaches of the river bend and stretch, and the velocity becomes slow, showing a gentle and circuitous scene.
Chaoyang City is located in the transition zone from Inner Mongolia Plateau to coastal plain. It is a mountainous and hilly area in the west of Liaoning Province with insufficient water resources. According to the geological structure and water bearing characteristics of rocks, the groundwater in Chaoyang area can be divided into four categories: pore water of loose strata, fissure water of carbonate rocks, pore water of clastic rocks and fissure water of bedrock. The chemical types of groundwater in most areas are calcium bicarbonate and calcium magnesium type, followed by calcium bicarbonate and calcium sodium type. In some areas, there are calcium chloride sulfate type water and calcium bicarbonate sulfate type water. In some areas, the fluorine content in shallow groundwater is higher. The salinity of the water is generally about 0.3 g / L, the highest is not more than 1 g / L, and the pH value is between 7 and 8.0, which belongs to neutral to weakly alkaline water. The surface water of Chaoyang City is mainly precipitation and runoff, and precipitation is the supply source of water resources.
Chaoyang City is a semi-arid temperate deciduous broad-leaved forest zone with North China flora transiting northward to arid grassland type. Due to the complex geomorphic types, uneven distribution of heat resources and great differences in temperature and precipitation, there are obvious differences in the distribution of plant resources between North and south. In the south, the vegetation condition is good, which has the characteristics of North China flora; in the north, the ecological function is poor, and there are many drought type plants in Inner Mongolia. There are more than 1500 kinds of vascular plants in the city, including more than 220 kinds of woody plants (trees and shrubs), and some rare plants. Plant resources include forest resources, grassland resources and wild economic plant resources. There are many kinds of plants in Chaoyang City
