Eichhornia crassipes Emergency Investigation in the Wuhan Section of Changjiang River and Hanjiang River Downstream
Abstract: In August 2015, there was an outbreak of Eichhornia crassipes in the Wuhan section of Changjiang River and Hanjiang River downstream. The Bureau of Hydrology, Changjiang River Water Resources Commission immediately launched the emergency monitoring plan to conduct field survey. Results of the survey show that Eichhornia crassipes in the Wuhan section of Changjiang River is mainly from the tributaries of Hanjiang River, such as Hanzha River. The Eichhornia crassipes in the branch of Hanjiang River mainly come from the lower reaches of Hanjiang River in plain river network area. In the flood period when Eichhornia crassipes grows vigorously, the sudden heavy rainfall leads to the river water level rising, which will discharge Eichhornia crassipes gathering in the still water into the river downstream, until Changjiang River. The outbreak of Eichhornia crassipes event although does not have a greater impact to the water quality of Changjiang River, it has already caused great attention of the concerned department.
