The hottest transportation hub in Southwest Guizho

Guizhou: a transportation hub in Southwest China

Guide: Guizhou is abbreviated as Guizhou or Guizhou for short. It is located in the east of the Yunnan Guizhou Plateau in Southwest China, with an area of 170000 square kilometers from 10337 to 10932 east longitude and 2437 to 2913 north latitude. The mountains are high and the valleys are deep, with more than 300 dams (jujube shaped basins) covering more than 1000 mu. The province governs Guiyang, Liupanshui, Zun

Guizhou, abbreviated as "Qian" or "Gui", is located in the east of Yunnan Guizhou Plateau in Southwest China, with an area of 170000 square kilometers from 103 ° 37 'to 109 ° 32' east longitude and 24 ° 37 'to 29 ° 13' north latitude. The mountains are high and the valleys are deep, with more than 300 dams (jujube shaped basins) covering more than 1000 mu

the province governs Guiyang, Liupanshui, Zunyi, three provincial cities, Anshun, Bijie and Tongren, and three autonomous prefectures in southeast, South and southwest Guizhou. There are 9 county-level cities, including Zunyi, Anshun, Kaili, Duyun, Tongren, Xingyi, Bijie, Chishui, Qingzhen and Renhuai, and 56 counties, 11 autonomous counties, 3 special zones and 6 municipal districts. Guiyang, the provincial capital

Guizhou has no severe cold in winter and intense heat in summer. The annual average temperature in most areas is 14-16 ℃. The average temperature in January, the coldest month, is more than 5 ℃, and the hottest month, July, is more than 25 ℃. There is abundant precipitation, with annual precipitation of 1100-1400mm generally, and sufficient heat. The accumulated temperature of activities above 10 ℃ is about 4000-5500 ℃, and the frost free period is always more than 270 days, and the rain and heat are in the same season, which is conducive to plant production. Due to the influence of terrain, latitude and other factors, the climate in the province has changed significantly from east to west, from south to north, and from low to high, forming a variety of climate types, creating superior climate conditions for the comprehensive development of agriculture and diversified management. However, due to the rainy days up to 160 days, the relative humidity often reaches 80%, the sunshine is only 1200-1500 hours, and the sunshine rate is less than 25-30%, so there is a saying that "there is no sunny day for three days", which is unfavorable to light loving crops. Because of the large monthly variation rate of rainfall, drought will also occur. In addition, there are hail in spring and summer, "autumn wind" low temperature and other disastrous weather that is not conducive to agriculture

landform

Guizhou has diverse landforms, 570 kilometers long from east to west, 510 kilometers wide from north to south, and an area of 17.61 square kilometers. It is a plateau inclined from west to East, rising between Sichuan Basin and Guangxi basin. The West and northwest are connected with Yunnan Plateau, Hunan hills in the East, Guangxi basin in the South and Sichuan Basin in the north. Most areas of Guizhou Plateau are about one kilometer above sea level. The terrain in the west, northwest and southwest is relatively high, especially in Weining, Hezhang and other counties in the west, with an altitude of 1500 to 2400 meters. In addition, some ridges and main peaks in other regions, such as Fanjing Mountain in the northeast, Yunwu Mountain in the middle and Dalou mountain in the north, are also more than 1500 meters above sea level

the terrain of Guizhou gradually decreases from west to northeast and south. Most of the central part is about one kilometer above sea level, between 500 and 800 meters in the East and southeast of Guizhou, and between 500 and 1000 meters in the north and south of Guizhou. Some counties located at the edge of the plateau and river valley, such as Shudian, Libo, Jinping, Tongren, Chishui and other counties, have the lowest altitude. Chishui River Valley is about 500 meters away. The vast area between 700 and 1500 meters above sea level is the area with the most concentrated distribution of dams

on this rugged cutting plateau in Guizhou, mountains, hills, river valleys, basins and plains are crisscrossed, and the terrain is extremely complex. The highest place in the province is Jiucaiping at the junction of Hezhang County, Weining County and Liupanshui City, with an altitude of 2900 meters, while the lowest place is at the exit of Shuikou River, a tributary of Duliu River in Liping County, with an altitude of only 137 meters. This one fell together, and it really felt like going to heaven and earth

rivers and lakes

rivers in Guizhou mostly originate in the middle and West, and flow northward, East and south along the terrain. Most of the river valleys are narrow and deep, the riverbed slope is large, there are many waterfalls, reefs, dangerous beaches, and the water flow is rapid, and the phenomenon of sudden rise and fall of water level is obvious. It is rich in hydraulic resources. To the north of Miaoling is the Yangtze River Basin, accounting for about 7/10 of the total area of the province Wujiang River is the largest tributary of the Yangtze River in the province, with a drainage area accounting for 4/10 of the province's area. Its tributaries include Maotiao River, Qingshui River, etc. Chishui River, another important tributary of the Yangtze River in the province, flows through the two sections of the Sichuan Guizhou provincial boundary, with many beaches. The rivers south of Miaoling belong to the Pearl River system, and the drainage area accounts for about 3/10 of the total area of the province Rivers flow through karst areas, and the river water often leaks or dives into the ground, becoming an undercurrent. With Nanpan River and Beipan River as the main rivers, Huangguoshu waterfall on Baishui River, the source of Dabang River, a tributary of Beipan River, is 20 meters wide and 57 meters high. It is a magnificent waterfall in China. Two kilometers upstream, there are eight cascades, forming a cascade of waterfalls

there are few lakes in Guizhou, among which the largest lake is Caohai, with an area of 45 square kilometers

industry

after more than 40 years of construction, especially during the "third line" construction period in the 1960s and 1970s, the centralized investment of the state has undergone profound changes, and the economic strength has increased rapidly. In 1996, the provincial GDP increased by 8.7% over the previous year, with an average annual growth rate of 9.3%. A number of large and medium-sized backbone projects have been completed and put into operation, basically forming an energy and raw material industrial system, a machinery and electronic industrial system, and a light textile industrial system characterized by its own resources and technological advantages. The energy industry is dominated by coal and electricity. Guizhou is the province that exports the most commercial coal in Jiangnan. The power industry has both water and fire. In addition to meeting the needs of Guangdong Province, which consumes a large amount of oil raw materials, Guizhou has begun to transmit power to Guangdong and neighboring provinces. The raw material industry is dominated by non-ferrous metals, metallurgy, chemical industry and building materials. It is an important production base of raw material products such as electrolytic aluminum, mercury, titanium, ferroalloy, pig iron, brazing steel, refined antimony and phosphate rock in China. The mechanical and electronic industry has three major military industrial bases of aerospace, aviation and electronics, as well as a number of enterprise groups and backbone enterprises such as automobiles, auto parts, abrasives and abrasives, engineering machinery, internal combustion engines, industrial bearings, low-voltage electrical appliances, precision optical instruments, industrial instruments and meters, and special precision machine tools. It has complete categories, sophisticated equipment, and strong technology. The technical level, quality, and output of many products are among the best in the country. The light textile industry includes the food industry with the focus on famous wine, tobacco and mineral water, the textile industry with the characteristics of cotton, hemp, wool spinning, silk weaving, chemical weaving, leather making, and other light industries such as papermaking, among which cigarettes and alcohol occupy an important position in China. Mineral springs have excellent water quality and large quantity, and the development prospect is very considerable

transportation

transportation is the top priority of Guizhou's economic development. Guizhou is a transportation hub in Southwest China. It has formed a three-dimensional transportation network with Guiyang as its center with special structure and diverse functions, railways and highways as its framework, and water transportation and civil aviation combined. Guiyang Kunming railway, Sichuan Guizhou railway, Guizhou Guangxi railway and Hunan Guizhou railway intersect in Guiyang and run through the whole province. The traffic mileage is 1418 kilometers, the electrified traffic mileage is 1142 kilometers, and 26 railway stations are built. The construction of Shuibai electrified railway with a total length of 121 kilometers has started. After completion, it will form a South to North corridor in the southwest together with Nanning Kunming railway and Neijiang Kunming railway. The electrification recovery capacity of Shuizhu railway is still increasing, and the line project is about to start, with a length of 600 kilometers in Guizhou. Guiyang south railway station is the largest marshalling station for railway transportation in Southwest China, with a daily marshalling capacity of 8000 vehicles. Guizhou has opened international large-scale container business, and the freight port has been opened in 1995. The pace of highway construction in Guizhou has accelerated, with 13465 kilometers of highways (3939 kilometers of high-grade highways) open to traffic in the province. Guihuang and Guizun high-grade highways reach the west line and North line tourist areas respectively. Huaxi Avenue closely connects Guiyang, the provincial capital, with Huaxi, the Pearl of the plateau. The construction of Guiyang Gaoxin highway leading to Guangxi and running through the south line tourist area has begun, and the construction of Guiyang Bixi and Zunchong highways has begun preliminary work. Class 4D modern airport Guiyang Airport has been opened to traffic. Many airlines have opened flights from Guiyang to 32 cities including Beijing, Tianjin, Zhengzhou, Shanghai, Ningbo, Qingdao, Guangzhou, Shenzhen, Haikou, Chengdu, Kunming, Wuhan, and the Hong Kong Special Administrative Region
