How long and wide is the Funan River in Chengdu?

Minjiang River system flows through two main rivers in Chengdu, one of the four rivers introduced by Dujiangyan: Zouma River, which flows into Chengdu to form Fuhe River and Nanhe River. After entering Chengdu, the Fuhe River flows around the north and east, and the South River flows around the west and south to meet in Hejiang Pavilion. After meeting, call Fuhe. Funan River has a history of 2,300 years and once brought glory to Chengdu. However, after the 1960s, due to man-made and natural reasons, the water quality gradually deteriorated. There is a jingle that reads: "In the 1950s, rice was washed and vegetables were washed; in the 1960s, the water quality deteriorated; in the 1970s, fish and shrimp thundered; in the 1980s, the toilet seat was not washed." It was 1986, when a pupil of Longjiang Road Primary School first proposed to renovate the Funan River. At that time, he wrote to the mayor and proposed "give me back the clear water of Jinjiang". However, because the second ring road was being built by the municipal government at that time, no more manpower, material resources and financial resources were invested in the Funan River, so it was demonstrated for five years from 1987 to 1992, and it was implemented in five years from 1992 to 1997, with a total investment of about 2.7 billion yuan. There are five hidden dangers in our Funan River. In view of these five hidden dangers, we have carried out five major renovation projects. 1. Flood control works: the river bank is short, the river channel is silted, the river channel is narrow, and the flood control capacity is seriously insufficient. It is the worst among the provincial capital cities in China, with a flood control capacity of 664 cubic meters per second, while the water flow in Baokou Port is more than 700 cubic meters per second, which means that the fan-shaped alluvial plain in Chengdu can be submerged only by the water in Baokou Port. This time, the newly-built river bank18km will be rectified and the river bank will be reinforced. Taohe River 16km, newly built and rebuilt river-crossing bridges 17, and built piers 12. The width of the river channel is widened from 30-80m to 40- 120m, and the flood discharge capacity is increased to 1299 m3. It turns out that Chengdu has a major disaster in ten years, and there are minor disasters every year. Now the flood control standard has been raised from once every ten years to once every two hundred years. It turns out that in the flood season, residents along the river will send people to stand guard at night, ring gongs to warn them and move their families. 2. Environmental protection project: Funan River is very polluted. There are many sewage outlets along the coast, which discharge more than 600,000 tons of sewage every day, with 15 kinds of harmful substances. Because of water pollution in coastal areas, trees died, wells were abandoned, tap water was turned off, and domestic sewage of coastal residents and sewage from public toilets were directly discharged into rivers. The first step to control pollution is to intercept sewage. We buried a pipeline outside Hanoi, and all the sewage was intercepted and brought to Sanhe treatment plant before being discharged into the river. Some polluting factories along the river have also moved away. 3. Greening project: The river should have been the easiest port to build a green belt, but the remaining trees were left unattended and left to fend for themselves. Our greening project has newly opened up green space and built an open garden, which is divided into four scenic spots: spring, summer, autumn and winter. 4. Road pipe network project: all the original pipelines are worn out. For example, there is only one public toilet and one water pipe, and disputes often occur during peak use, and the wires are overwhelmed. The bought electrical appliances are shelved and the road is very narrow. In case of fire, the fire truck can't enter. There is no natural gas pipeline, and residents mostly use honeycomb coal. In this project, the inner ring road, the outer ring road and the river channel are built, and various pipelines are laid at the same time. 5. Residential housing projects. Residents used to live in dark, damp and crowded diaojiao buildings and were often disturbed by floods. After the renovation, these 30 households with 654.38 million people were moved into more than 20 new residential areas around the Second Ring Road, forming 687 mu of new business areas and 860 mu of commercial and residential areas on the original site. To show their gratitude, residents presented more than 1000 pennants to the comprehensive improvement office. This project has the highest cost, costing 1 1 100 million yuan. This comprehensive renovation cost 2.7 billion yuan, which we have been waiting for for a long time: the "Jade Necklace" is about to take shape, which has great influence at home and abroad. Shanghai, Tianjin and other cities 16 all sent delegations to test and learn from the experience.

Now it's renamed Jinjiang. Jinjiang is now composed of Fuhe River and Nanhe River. Fuhe River starts from Dongzikou, jinniu district and ends in Jiangkou Town, pengshan county, with a total length of 97.3 kilometers. Nanhe River starts from Songxian Bridge and ends at Hejiang Pavilion, with a total length of 5.63 kilometers.
