The Jin River is a river of Sichuan, China. It flows through the provincial capital of Chengdu. It consists of three parts: the Fu River, an extension of the Fu River and the Nan River(Chinese: 南河). The Jin River has a long and complex cultural history, dating back to 256 BC when it was formed. Over the course of several dynasties, the Jin River has been given different names by the ruler in power at the time. Flowing the provincial capital of Chengdu city, the river historically provided a source for irrigation, boat travel, and a means to dispose of wastewater. As the cities’ population increased, pollution of the river became a major environmental concern leading to regulation projects beginning in 1993. The current ecological state of the river is degraded as it is overloaded with dissolved nitrogen and phosphorus inputs from urban sources. Alongside the riverbank of the Jin River, theme parks were built and numerous tourism programs were created.
