It is the rivers and lakes that have bred up people of Wuhan for generations. Unfortunately, urban lakes have fallen into an awkward situation with the rapid development of urbanization and sharp increase of urban population in recently years. The numbers and areas of urban lake have sharply decreased; some urban lakes have deposited; some became swamp. Additionally, soil erosion caused by human factors has shoaled lakes and reduced reservoir capacity. Trade-waste sewage and domestic sewage flow into lakes, which has caused the deterioration of water quality.

然而随着近年来城市开发的力度不断加大，城市人口的快速增长，城市湖泊陷入了十分难堪的地步：湖泊数量锐减；水面面积急剧缩小；湖泊淤积严重，部分湖泊逐渐沼泽化，再加上人为因素造成的水土流失，使湖泊变浅，库容量降低；生产生活污水的大量排放使湖泊水质恶化。
