| 摘要: |
| 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. |

| Abstract: |
| 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. |
