太湖流域经济发展及其对洪涝的影响

太湖流域是我国最发达的地区之一,流域社会经济发展迅速,经济总量在全国占重要地位。太湖流域经济发展的特点是：经济发展迅速、城市化规模大、流域内区域差异明显。本文就经济发展所带来的洪涝问题做了分析,具体表现为：经济发展,地区承灾能力下降,洪涝灾害损失加大;土地利用变化,流域产水量增加,改变了洪涝形势;地面下沉影响了防洪工程的效益;圩区建设在发挥巨大的防洪除涝效益的同时,也带来负面效益。

Economic Development And Its Impact to Flood Disaster In Taihu Basin

As a most developed region in China, Taihu Basin, which with a quickly economic development, has a important status in China economic development. The economic characters of Taihu Basin are quick development, large urbanization, and economic difference in spatial distribution. Impacts to floods by some pyromania of eco society development, such as land use change, urbanization, economic development, polder construction, were analyzed in this paper. The main conclusions included: (1) economic development made flood losses increase; (2)as land use changed, runoff increased; (3) land surface sedimentation resulted flood control engineering lost some capacities; (4) polders protect some land from flooding, but polder construction led quicker runoff.
