Geographical environment of Liaodong Peninsula
Liaodong Peninsula, located in the south of Liaoning Province, is the second largest peninsula in China. China, the southeast of Liaoning Province, extends to the peninsula between the Bohai Sea and the Yellow Sea. The northeast is adjacent to Changbai Mountain, with the Qian Shan Mountains in the middle. The elevation of individual peaks is more than 1 000m (the highest point is Yunshan 1, 13 1m), and most of them are low hills. There are sea erosion terraces along the coast. The rivers on the peninsula are short and the valleys are narrow. Biliu River and Daqing River both flow into the sea separately.
Jinzhou Bay and Dalian Bay, near Jinzhou District in the south of the peninsula, are two tectonic basins, which declined in the modern geological period, forming a curved coastline, and there are good ports such as Lushun and Dalian, which are important shipping and fishery bases in northern China. Its northern boundary is the connection between the mouth of Yalu River and the mouth of Liaohe River, and the other three faces the sea. The Qian Shan Mountains run through the peninsula from south to north. The highest point is higher than1000 m. The coastal area of the peninsula is plain, and there are many islands in the sea. The most famous ones are Xiaolong Island (Snake Island) and Changshan Islands.
Dalian in the south of the peninsula is one of the excellent seaports in China, with beautiful scenery and a famous tourist attraction. Its northern border is the Yalu River Qian Shan Mountains, which runs through the whole peninsula from south to north. Due to the influence of maritime climate, the peninsula is warm in winter and cool in summer, and summer is a summer resort. The warm climate makes this peninsula a good fruit producing area.
Liaodong Peninsula, with mild climate, is a concentrated apple producing area and the largest export base. Other products include apples, pears, peaches and hawthorn. Other crops include corn, rice, sorghum, soybeans and peanuts. Coal is produced in this peninsula. Tussah cocoon production accounts for two-thirds of the country. Important cities include Dalian, Dandong and Yingkou. Liaodong Peninsula is one of the three major peninsulas in China. Located in the south of Liaoning Province, it consists of mountains and mountains, and extends to the southwest to the ocean. Laotieshan, located at the southern tip of the peninsula, across the Bohai Strait, echoes the Shandong Peninsula from afar, forming the dividing line between the Bohai Sea and the Yellow Sea. Qian Shan Mountain Range, the backbone of the peninsula, starts from Lianshanguan in the north and reaches Laotieshan in the south, which divides Liaodong Peninsula into two inclined planes. The southeast slope is relatively gentle, with long water systems such as Dayang River, Naying River, Biliu River and Dasha River flowing into the Yellow Sea. The northwest slope is steep, with short water systems such as Daqing River, Xiongyue River and Fuzhou River flowing into the Bohai Sea. The coastline of Liaodong Peninsula is more than 1000 kilometers long, and there are many long mountain islands along the coast.
Qian Shan vein divides Liaodong Peninsula into two inclined planes. The annual runoff depth of Liaodong Peninsula is less than 400 mm, and the runoff coefficient is mostly 40%. The summer runoff accounts for 65% of the whole year, and the water level fluctuates greatly. The soil is mainly brown soil, the lowlands in the valley are straw mats, and saline soil is distributed along the coast.
The northeast is adjacent to Changbai Mountain, with Qian Shan in the middle. Most of them are low mountains and hills, and some peaks are above 1000m (the highest is Buyun Mountain 1 13 1m). There are ocean terraces and alluvial plains along the coast. Broken terrain, short rivers and narrow valleys. Biliu River and Daqing River both flow into the sea separately. Generally, flood peaks are easy to disappear and not easy to flood. Occasionally, typhoons cross the border, which will form local disasters. The part south of Jinzhou District in Dalian is called Luda Peninsula.
Laotieshan is the only place for migratory birds to fly. The nearby Snake Island is the habitat of a large number of Agkistrodon halys in front of the main ridge of Liaodong Peninsula in Lushunkou, and Laotieshan Snake Island is one of the nature reserves in China. Liaodong Peninsula belongs to low mountains and hills in landform. Because it extends into the ocean, it is greatly influenced by the ocean, and the climate is warm and humid, belonging to the warm temperate monsoon climate. It is characterized by warm and rainy summer, being regulated by the ocean, and rarely having high temperature weather. Binhai is a summer resort. The annual average temperature in Liaodong Peninsula is 8- 10℃, the hottest month average temperature is 24-25℃, the most Leng Yue-10-5℃, the frost-free period is 160-2 15 days, and the annual precipitation is 550-900 mm, 60%.
It has a warm temperate humid climate, which is regulated by the ocean. The extreme maximum temperature in summer rarely exceeds 35℃. The annual precipitation is 650 ~ 950 mm. Excellent natural conditions, developed agriculture, rich in corn, rice, sorghum, millet, potatoes, soybeans, peanuts and so on. It is the concentrated production area and the largest export base of apples.
