【Abstract】 During Ming and Qing periods, the floods caused by Yellow and Huai river flew violently and frequently into Lixia River in north Jiangsu Province. After the floods receded periodically, a great deal of sand was deposited, the streams, lakes and harbors were silted up seriously, and this led to final disappearance of Sheyang Lake. Consequently the change of natural environment from lagoon to level farmland was completed in Lixia River basin. As a result the flood rampaged, and the calamities became more heavier than the past. The interplay between flood disaster and natural environment brought about Lixia River valley an utterly poverty-stricken area.更多还原
