Jin River (Sichuan)

Course and tributaries Jin River is located in the western region of Sichuan Basin and the eastern region of Qinghai Tibet Plateau. The Fu River and the Nan River, the two components of the Jin River, encircle the ancient city of Chengdu. From the confluence point to Hexin Village, the Baidu Map calls this reach the Fu River. ==Naming==

The Jin River, composed of the Fu River, the Nan River, and the river channel from Hexin Village of Chengdu to the Min River, have been renamed several times over the course of different dynasties. The Fu River was first known as the Pi River, Shiqiao River, or Qingyuan River when the city was called the Chengdu Mansion. After the Ming Dynasty (1368-1644), the Nan River was known as Wenjian, Dajian, Shengjiang River, Shengqiao Water, Qingjiang, Qingshui River, Fenshui, Fenjian, Guanjin River, and Jinshui. In history, the Fu and the Nan River components of the Jin River were understood unofficially by the people as the "Funan River" for short. This was deemed too informal and was rectified on May 10, 2005, by the Sichuan Provincial People's Government. They are now officially named as their distinct channels. ==Ecology==

Urban ecology The current Jin River has eutrophication issues caused by different types of urban wastewater such as sewage discharge, road surface runoff, and effluent. Eutrophication is caused by excessive amounts of total dissolved phosphorus (TDP) and total dissolved nitrogen (TDN) in both the Fu River and the Nan River. The N-limiting condition in both the Fu River and the Nan River can pose a potential biological hazard. If any wastewater or effluent that contains a large amount of TDN enter the river, it is likely to trigger an algal bloom. Sediment studies in the Jin River show that the accumulated N and P in benthic sediments far exceed the P and N concentration in both the surface micro-layer and the sub-surface layer. ==History==

Commercial navigation Historically, the Jin River was once a wide channel that had enough water volume to support boat travel in and out of Chengdu. At the end of the 1980s, due to increased populations and the development of Chengdu, the appearance of the Jin River changed with greater rates of sediment accumulation. This project also stabilized river banks and built dikes along the river channel in order to prevent flooding caused by sedimentation. after the 5-year river-cleaning project in 1997. The Municipal People's Government was awarded a prize for improving the environment of the river, from the United Nations. ==Recreation and tourism==

Night-Tour Jin River “Night-Tour Jin River” is located on the Jin River Green Road which is along the Jin River in Chengdu, from the Dongmen Pier to He Jiang Ting section. The whole tour takes "Jin River story scroll" as the main storyline, consisting of four parts: Urban Leisure, Dongmen Market, Downtown Meditation and Jin Guan Ancient Courier Station. [Starting from Dongmen Pier]: Path: Dongmen Bridge → Buddha Show → Pier story → December City →Architectural Light and Shadow Show → Sailing Show →Water Curtain Fountain →He Jiang Ting → Corridor Bridge [Starting from Music Plaza]: Path: Corridor Bridge → He Jiang Ting → Water Curtain Fountain → Sailing Show → Architectural Light and Shadow Show → December City → Pier Story → Buddha Show → Dongmen Bridge Living Water Garden Chengdu Living Water Garden is the first urban eco-environmental park with water as its theme in the world. It is located on the bank of the Jin River, which is across from the Huaxing Road Meng Zhou Wan, Jin Jiang District, Chengdu. After a variety of treatment processes, the river water, which was polluted by the upstream sources and urban domestic sewage, flows back into the Fu River. Every day, the storage of Living Water Garden can reach 300 cubic meters, demonstrating the process of polluted water from "Turbid" to "Clear" and from "Dead" to "Alive" in nature. Due to the combination of ecological, aesthetic, cultural and educational functions, Living Water Garden has won the "Excellent Waterfront Award" of the International Waterfront Centre in 1998, the "Environmental Design Award" jointly evaluated by the International Association for environmental design and regional magazine of the United States (juxtaposed with the Thames River Treatment Project in the United Kingdom), as well as several international awards including the 1998 UN Habitat Award Awards. At present, it has become one of the most visited parks in Chengdu. ==References==
