The geographical coordinates of Liaoyang City are East longitude12235'-12340'; North latitude 40 42'-4136'. Liaoyang has a total area of 4,743 square kilometers, with a length of 92.3 kilometers from east to west and a length of 100.3 kilometers from north to south. Liaoyang city is located in the transition zone between Liaodong low hill and Liaohe plain, with complete landform types and obvious differentiation law, typical layered landform and landform zoning law. From Baiyun Mountain in the southeastern border to the bank of the northwest boundary river (Hunhe River), the terrain is from high to low, from Zhongshan, low mountains, high hills, low hills and terraces to the plain, with distinct layers, and the altitude drops from more than 1000 meters to less than 50 meters, which constitutes the same-direction inclined gentle descent terrain with high in the southeast and low in the northwest. It borders Xiuyan County, Fengcheng County and Benxi County. Shuiquan Township is the highest point in Liaoyang, and Daheishan is the highest peak in China, with an altitude of 1 18 1 m. The lowest point is the coastal city of taian county and Tangmazhai and Jiamu Town in Liaozhong County.

The dividing line between the eastern and southeastern parts of Liaoyang is northeast from south to north, and the main branch of the middle part of Qian Shan is composed of a series of peaks such as Huxiantang Mountain, Daheishan Mountain and Motianling Mountain. Taking this branch of Qian Shan as the main branch, there are several veins, such as Zhengcha, Shengtieling, Dalazi, Laoyeling, Maer Mountain and Waitaoshan, which are arranged in a north-south direction from east to west.

There are 66 peaks 166 in China, including Liaoyang county 126, dengta city 27, taizihe district 5, Gongchangling 5, Hongwei 2 and Wensheng 1 seat.

Motianling is 968.8 meters above sea level, and its main peak is located 3.5 kilometers southeast of Li Jiacun, the hometown of sweet water. It is the boundary mountain between Liaoyang and Benxi, and it is also the boundary mountain between sweet water and water springs. Mountain area 19 km2, north-south trend, steep slope, vegetation coverage rate of over 90%. Hebei Zhengcha is 906.3 meters above sea level, and its main peak is located 2.7 kilometers southeast of Hebei residential area in Helan Town. It is the boundary mountain between Liaoyang City and Xiuyan County. The elevation of Dalazi is 5 14. 1 m, and the main peak is located at the southeast of Jixiangyu Village in Longchang Town 1.2 km.

Baojing Mountain is 272.2 meters above sea level, and its main peak is located in the south of Husha Erdaogou Village, Luodatai Town. Liaoyang belongs to Liaodong sub-region of North China stratigraphic region, and the main exposed strata are complex. From old to new, it can be divided into eight stratigraphic systems: Pre-Sinian, Sinian, Cambrian, Ordovician, Carboniferous, Permian, Jurassic and Quaternary.

Quaternary strata is a geological phenomenon widely distributed in Liaoyang area. The Quaternary strata in the west near the Lower Liaohe Plain are dominated by river alluvial facies, which is extremely developed and its thickness gradually increases from the piedmont to the west. The average thickness of the piedmont stratum is about 70 meters, which gradually increases to nearly 100 meters along the Shenyang-Dalian Highway and to about 300 meters at the edge of the Hunhe River. The Quaternary strata in the eastern mountainous area of Liaoyang are undeveloped, and only distributed in strips along the Tanghe River and He Lan Valley. Its causes are mainly alluvial, alluvial, diluvial, aeolian and moraine. The climate characteristics of Liaoyang area are also different because of the different landforms.

A temperate humid monsoon climate is formed in the eastern hilly areas, including the towns of Shuiquan, Tianshui, Hanling, Helan, Shangmatun, Taziling, Jidongyu, Longchang, Bahui and Xiadahe in Liaoyang County and the south of Gongchangling District. The climate is characterized by abundant precipitation, heavy rain and heavy rain. The average annual precipitation is between 800-900 mm, mostly concentrated in summer, especially in Liaoyang area. The temperature is low, the annual average temperature is 6-8℃, the frost-free period is 140 ~ 160 days, and the annual average positive accumulated temperature is 3000-3400℃.

A temperate semi-humid monsoon climate is formed in the northern hilly plain, including Liuhezi, Jiguanshan, Xidayao, Huazi, Lighthouse, Hu Sha, Liutiaozhai, Gucheng Street, Ximafeng and other places in dengta city, as well as Lanjia Town and Xiaotun Town in northern Wang Jiazhen, Anping Township in Gongchangling District and Tonkin Ridge Township in taizihe district. The climate is characterized by long cold period, low temperature, windy spring and less rainfall than hilly areas. The annual average precipitation is 500 ~ 700 mm, the annual average temperature is 6 ~ 8℃, the frost-free period is about 150 days, and the annual average positive accumulated temperature is 3 100 ~ 3400℃.

A warm temperate semi-humid climate is formed in the plain area along the river in the west, including Shoushan, Shaling, Huangniwa, Liu Erbao, Liu Hao, Jiamu, Xiaobeihe and Tangmazhai in Liaoyang County, Tongerbao Town in dengta city and most parts of Wang Jiazhen. The climate is characterized by strong continental climate, high temperature in summer and low temperature in winter, and more precipitation than that in northern hilly areas, mostly concentrated in the crop growing season from May to 10. The annual average temperature is 8-9℃, the precipitation is 600-800 mm, the frost-free period is 160 to 180 days, and the annual accumulated temperature is above 3400℃. The geology, geomorphology, climate characteristics and geological structural conditions of Liaoyang area determine that Liaoyang area is a rare high-quality water-rich area in Northeast China. Water resources in Liaoyang area. As early as 70 years ago, it was famous in Asia when it was exploited by Japanese imperialism and used by Anshan Iron and Steel Plant (later changed to Showa Iron and Steel Plant), the largest steel joint production base in the East, to plunder China's steel resources. They are domestic water for about 2 million people in Liaoyang and Anshan, industrial water for two super-large enterprises in Angang and Liao Hua, farmland irrigation for about 6.5438+0.5 million mu in Liaoyang and domestic water for 6.5438+0.2 million rural people. Shoushan water source supplies 230 million cubic meters of groundwater to Anshan area every year. Resulting in a large funnel. Therefore, the water resources in Liaoyang city are becoming increasingly tense, and attention should be paid to the protection and rational development of water resources. It is very important to put an end to water waste and save water.

There are 86 large and small rivers with a flow of more than 5 kilometers in Liaoyang City, including 29 large and small rivers with a flow of more than 10 kilometers. These rivers form two major water systems: Taizi River and Hun River.

During the Warring States Period, Taizi River was called Yanshui, also called Daliangshui. Liang Shui or Liang Shui was called in Han Dynasty. "Taizi River is the reason why it flows into the water. Yan Taizi Dan is hidden in the water, and later generations named it after Taizi River" (Reading Historical Records). Also known as Liang Donghe. In the Ming Dynasty, it was called the Daizi River. In Qing Dynasty, Manchu called it "Houlle Hubila" (Houlle called it a reed and Bila a river), but it didn't spread for a long time, and it is still called Taizi River, which is still used today.

The Taizi River has two sources, the north of which originates from Hongyangou, Pingdingshan Township, Xinbin County. Originated in the south to the foothills of Caomaozi Mountain in Yanghugou, Dongying Square, Huanren County, it joins Guzi Village and Machengzi Village in Benxi County and enters Liaoyang via Benxi City. After entering Qiwo Reservoir in Jiguanshan Township and Hanling Town, it passes through Gongchangling, Xidayao, Hu Sha, Xiaotun, Tokyo Mausoleum and its suburbs, and then passes through Wangshuitai, Ximafeng, Wang Jia, Tongerbao, Huangniwa, Xiaobeihe, Liu Hao, Tangmazhai and other towns 18. The length of the river is 4 13km, the domestic flow is 143km, and the drainage area is about 4000km2, accounting for 85% of the total area of Liaoyang. Most rivers in China are tributaries of Taizi River, among which there are as many as 24 tributaries, and the flow exceeds 10 km. It flows into the Taizi River from north, east and south, forming a centripetal water system.
