Short summary
In the middle and lower reaches of the Hanjiang River in February 2018, another serious diatom bloom occurred. This paper analyzes the key hydrological factors that occur in this diatom bloom and proposes a water dispatching optimization plan and specific countermeasures. The suggestion is that Comprehensive protection of the Hanjiang River water ecological environment, completely solve the watershed problem of non-point source pollution.
