[0039] Example 1: Comprehensive development and utilization of Poyang Lake
[0040] At present, Jiangxi is preparing to "block" Poyang Lake, the largest freshwater lake wetland in China. The name of this project is: Poyang Lake Water Conservancy Project. If this project is followed, the lifespan of Poyang Lake, China's largest freshwater lake wetland, will be reduced by 1 / 3, and due to water storage during the dry season, the endogenous pollution of Poyang Lake wetland will increase significantly, accelerating the eutrophication process of Poyang Lake. If Poyang Lake is developed and utilized in the way of building rivers around the lake, only by reducing the sedimentation of Poyang Lake, the life span of Poyang Lake can be increased by 13 times. According to the calculation that the lifespan of Poyang Lake is 2000 years [1] and the annual ecological and economic benefits of Poyang Lake wetland ecosystem are 156.4 billion [2], the former will cause the loss of economic benefit...

[0041] Example 2: The root cause of pollution in Taihu Lake
[0042] Although the state and local governments have invested 111.498 billion yuan [3] to remediate water pollution in the Taihu Lake Basin (completed in 2015), the eutrophication pollution in Taihu Lake cannot be eradicated. And the pollution that the eutrophication of Taihu Lake causes is the core problem of the water environment pollution in the Taihu Lake Basin, and is also the bottleneck of the water environment governance problem in the Taihu Lake Basin. If the method for building rivers around the lake of the present invention is adopted to develop and utilize Taihu Lake, we will put an end to large Part of the pollution enters Taihu Lake. Combined with the dredging and sewage discharge method of rivers in lakes assembled by components (another invention of the author), to carry out dredging and sewage discharge on Taihu Lake, then we can not only eradicate the eutrophication pollution of Taihu Lake, but also...
