Wetland refers to the transitional zone between land and water, and together with forests and oceans, it is called the three major ecosystems of the earth, which plays an important role in maintaining biodiversity, regulating climate, resisting floods and so on. The great flood of the Yangtze River in 1998 finally made people realize that wetlands (especially the many lakes and marshes connected with the Yangtze River) can cushion the flood. However, many lakes are artificially isolated because of the need to reclaim land from the lake, leaving only a sluice gate rarely open to communicate with the Yangtze River. As a result, these naturally formed water networks were cut off and there was nothing they could do in the event of a flood.
