What are the five rivers, and how are they distributed?

Huai River, Hu River, Huang River, Tong River, Tuo River! Wuhe County, Bengbu City, Anhui Province is located in the northeast of Anhui Province, and is named after the five rivers of Huai, Hu, Huang, Tong and Tuo.

China is one of the countries with the most rivers in the world. China has many great rivers with long history. Among them, there are more than 1,500 rivers with a basin area of more than 1,000 square kilometers.

China's rivers follow the cycle of river runoff, including outflow rivers that flow into the ocean, and internal rivers that do not communicate with the ocean. The ten recognized rivers in China are the Yangtze River, the Yellow River, the Heilongjiang River, the Songhua River, the Pearl River, the Brahmaputra River, the Lancang River, and the Nu River.

The fifth largest river in China is the Songhua River.

The Songhua River is one of the seven major rivers in China.

1. The largest tributary of Heilongjiang (within the territory). Like the Heilongjiang River, the Songhua River also has two sources in the north and south, with a total length of 1,927 kilometers in the south source and a total length of 2,309 kilometers in the north source. The Songhua River flows into the Heilongjiang River in Tongjiang City, Heilongjiang Province.

As a native of Wuhe County, the answer for you is as follows:

The source of the Huhe River is in the south of the Yellow River in the northern suburbs of Shangqiu County, the basin is located between the Tuohe River Basin and the Vortex River Basin in eastern Henan, belongs to the water system of the Huangtong River, travels eastward through the south of Yongcheng City, and gathers into the Wuyang County of Anhui Province in Likou, with a basin area of 2040 square kilometers, mainly composed of two tributaries of the Bao River and the Dongsha River. The Baohe River enters Anhui from Yongcheng County, and flows into the main trunk of the Huhe River at Linjiji, with a basin area of 754 square kilometers in Baohe Province.

The Huhe River Basin is all in the Shangqiu area, across Shangqiu, Yucheng, Xiayi, Yongcheng 4 counties and Shangqiu City, with a total cultivated land of more than 2 million mu, the basin is the Yellow Flood alluvial plain, the basin is long and narrow, the middle and upper reaches are mainly controlled by two major tributaries, the average width of the basin, the Dongsha River is a kilometer, the Bao River is 54 kilometers, all are long and narrow. The terrain is inclined from northwest to southeast, gentle from beginning to end, slightly steep in the middle and upper sections, and the ground ratio is lower, with 1 4000 1 5000 in the upper reaches and 1 7000 1 8000 in the downstream. The micro-topography of the basin varies greatly, the upstream is mostly composed of small pond pits left by scouring, the topsoil is mostly sandy soil and sandy loam soil, the middle and lower reaches are mainly two-sided soil and silt, and the groundwater is very shallow.

The main tributaries of the basin, because of the yellow flood silt pad, most of them belong to the nature of the slope river, the section is shallow and small, the drainage is difficult, the overflow slope is discharged when the water is large, a vast ocean, but near the provincial boundary, the section suddenly becomes deeper, the drainage capacity of the flat trough is larger, there is no embankment on both banks, it is an underground river trough, this characteristic is quite beneficial to the river channel improvement in the basin.

The precipitation in the Huhe River Basin is small, the variability is large, the runoff is small, the interannual variation is large, and the distribution is extremely uneven within the year. The average annual flow of the Huangkou Hydrological Station is only cubic meters, the average annual natural runoff is 100 million cubic meters, the maximum annual runoff is (1963) billion cubic meters, and the minimum annual runoff is (1966) billion cubic meters, with drastic interannual variations. In normal years, the total annual runoff (guaranteed rate of 50%) is only 100 million cubic meters, the amount of surface water available is very small, and the distribution of runoff in the year is quite large, and the total runoff in the flood season (June and September) is more than 3 times larger than the total runoff in the dry season, so it is easy to drought, waterlogging and alkali is an important problem in this area.

Drought is a common phenomenon in the whole basin, but there are shallow and small rivers in the middle and upper reaches of the main and tributaries, lack of front and upper drainage systems, ditches criss-crossed, different sections up and down, the downstream along the river terrain is higher, the inland depression ponds and marshes, the slope water is difficult to discharge, and the groundwater is higher, in case of heavy rainfall, the ground is more waterlogged, the soil returns salt quickly, and the crop yield is easy to be reduced.

Wuhe County, Chengguan Town, Wuhe County, Bengbu City, Anhui Province, is located in the middle and lower reaches of the Huai River in northeast Anhui. With a total area of 1,428 square kilometers and a population of 660,000, the county has jurisdiction over 15 townships and towns, 1 provincial economic development zone (Chengnan Industrial Zone, a provincial nature reserve, 1 provincial forest park, and 240 villages (residences). Wuhe has a long history, and the county has been established for more than 900 years.

The most complete 100,000-year-old Huaihe ancient rhombodon fossil has been unearthed in the territory, and there are many Stone Age sites. Shunhe Street is a famous historical and cultural street in Anhui Province; In 2013, Yan's tomb was promoted to "National Key Cultural Relics Protection Unit".

Wuhe County is located at 117°26 -118°04 east longitude and 32°54 -33°21 north latitude. It is located in the northeast of Anhui Province and the middle reaches of the Huai River. It is bordered by Sihong County of Jiangsu Province in the east, Jiashan County and Fengyang County in the south, Bengbu City and Guzhen County in the west, and Si County and Lingbi County in the north.

The county border is about 56 kilometers long from east to west, about 45 kilometers wide from north to south, and the border is about 230 kilometers long, with a total area of 1,580 square kilometers. There are No. 104 National Highway running through the north and south in the county, the Huai River and the Huhe River running through the east and west, and the Wubang Highway and Wugu Highway connecting Bengbu and Guzhen in the west, becoming the hub of waterway and land transportation in northeast Anhui.

Affected by the eastern monsoon climate, Wuhe County belongs to the warm temperate transitional monsoon climate and is a semi-humid agricultural climate zone. The average annual temperature is millimeters, the average annual sunshine hours are hours, and the frost-free period is 212 days. The general climatic characteristics are:

The four seasons are distinct, and the monsoon climate is significant; The climate is mild, the rainfall is moderate, the sunshine is sufficient, the frost-free period is long, and the light, heat and water resources are relatively abundant. However, the transitional nature of climate and the variability of resources often bring about climate disasters such as drought and flood, continuous rain, low temperature, and frost. The average temperature of Wuhe County is the average annual temperature.

The hottest month is July, with an average monthly temperature; The coldest month is January, with an average monthly temperature of 0. The annual temperature range is. In terms of the average temperature of October, the average temperature of each decade throughout the year is the highest in late July.

There are two decades when the average temperature is higher than 28, that is, in late July and early August. The lowest in mid-January was 0-1. There are 4 months below 1, that is, from early January to early February.
