Yangxin, the world-famous "Hometown of Yali Pears in China", is located in the Yellow River Delta Development Zone in the northern plain of Shandong Province, at the junction of Shandong Peninsula and Beijing and Tianjin, with the geographical coordinates of East longitude 1 17. 15,- 1 17。 North latitude 52, 37. 26,-37。 43. The county is 26.5 kilometers long from north to south and 48.5 kilometers wide from east to west, with a total area of 792.49 square kilometers.
Yangxin county belongs to the Yellow River Plain. The county town is high in the west and low in the east, high in the south and low in the north, and inclines from southwest to northeast, with a slight fluctuation of slope, forming the landform characteristics of gentle hillock, slightly sloping flat land and shallow depression. The land in the county is mainly light and medium, and the soil layer is deep (about 8 meters).
The total land area of the county is1188,700 mu, of which 890,000 mu is usable and 706,000 mu is cultivated. The soil in China is divided into fluvo-aquic soil and saline soil. China has 46,700 hectares of arable land, all of which are composed of fluvo-aquic soil. Among them, 30,700 hectares of fluvo-aquic soil are mainly distributed in gently sloping hills and flat land with slight slope. It has good water and fertilizer conservation performance and is suitable for planting wheat, corn and fruit trees. There are 3033 hectares of cinnamon soil fluvo-aquic soil, scattered among gentle hills. Its performance is better than that of fluvo-aquic soil, and it is suitable for planting crops such as cotton and grain.
Salinized fluvo-aquic soil 13700 hectares, mostly located at the edge of shallow depression and the middle and lower end of slightly sloping flat land, mostly light soil and sandy soil. The performance is loose and the permeability is strong, but the soil fertility is thin because of water leakage and fertilizer leakage, so it is suitable for planting miscellaneous grains, cotton and root-swelling crops. Coastal tidal saline soil is 1 173 hectares, located in shallow depression, with high groundwater level, long-term salt content and few natural vegetation. Now through scientific alkali improvement and comprehensive management, a variety of alkali-tolerant crops can be planted.
Rivers in China have formed a relatively complete irrigation and drainage system. The main drainage rivers are Goupan River in the south of the county seat and Baiyang River in the north. These two rivers run through this county from east to west and flow into the sea from east. The irrigation channels are mainly Xingfu River (the second main canal) and a main canal in the west of the county, and the two main canals of Yellow River Diversion run through the north and south of the county. Two main canals of Yellow River Diversion are led out from Huimin County, and then the Yellow River water is led to the east and west sides of the county by the main canal of warm water line.
On the west of Goupan River, it starts from Houwanghan, Dehui Xinhe, Boli Township, the county, flows through Yangxin County from west to east, and continues to flow eastward into Zhanhua County, with a domestic flow of 44 kilometers and a drainage area of 499 square kilometers, and 200,000 hectares of arable land can be used for irrigation or drainage. Xingfu River (the second trunk) is the second branch of the artificially excavated Baijili Yellow River Diversion Canal 1958. Originating from Dazhujia Village, Zaohuli Township, Huimin County, the Yellow River Diversion Canal flows through Yangxin County from south to north, with a total length of 15km, a yellow river diversion capacity of 35m3/s and an effective irrigation area of 18700 hectares.
Yangxin county is located in the middle latitude and belongs to the warm temperate zone. Monsoon continental climate, four distinct seasons. The annual average temperature over the years is 12.3℃, the extreme maximum temperature is 40. 1℃, the extreme minimum temperature is -2 1.5℃, the highest temperature in Leng Yue is 1℃, and the hottest month is July.

water resource
Yangxin water resources are mainly divided into surface water and groundwater. In addition to atmospheric precipitation, the surface water transit capacity mainly includes Yellow River Diversion, Dehui New River and Shangdong River. Shallow groundwater fresh water is generally about 50 meters: the east of Laodian Town belongs to saline water area, and the salt content of groundwater is more than 5.0 g/L, which is not suitable for drinking; The chlorine and fluorine in deep groundwater (about 400 meters) seriously exceed the standard and are not suitable for drinking. The water source of Xingfu Reservoir comes from the Yellow River diversion, with a storage capacity of 2.5 million cubic meters, which mainly supplies fresh water for production and life in the county.
mineral resources
The proven underground resources in Yangxin mainly include oil, natural gas, methane and carbon dioxide. Oil and coal are difficult to exploit and are potential resources. Natural gas and other resources have broad development prospects.
land resources
The total land area is 79,200 hectares, including 46,700 hectares of cultivated land and 8,046.67 hectares of land to be developed. The county has flat land, deep soil layer, strong adaptability and great development potential.
Biological resources
There are more than 90 species of woody plants in 33 families and 265 species of herbaceous plants in 52 families. There are more than 20 kinds of animals, more than 30 kinds of insects and 8 kinds of fish.
