摘要
广州与曼谷都是沿海城市,历来受水灾侵扰,2011曼谷水灾损失严重,给亚洲城市敲响防洪警钟。文中通过对曼谷地理条件、气候变化、海平面上升和地面下沉等因素的分析,对比2011曼谷洪灾与广州重大水灾的成灾机制,认为广州不会重蹈曼谷数月浸淹式水灾的覆辙;但今后的防洪规划需具有全面性和前瞻性,充分考虑全球气候变化和城市化带来的影响。建议广州排水管网规划考虑城市化对微观地貌的改变,提高城市集水区排水容量和标准;顺应广州自然地势,合理利用湿地排水功能,将湿地纳入防洪体系。
As costal cities, both Guangzhou and Bangkok are suffered from flood disasters. The 2011 flood in Bangkok that caused heavy losses rang an alarm to other Asian cities for flood control. Analyzing the geographical conditions, climate change, sea level rise, and land subsidence in Bangkok, the paper summarizes the generation mechanism of the 2011 Bangkok flood. Through comparing the similarities and differences of generation mechanism between the two cities, the paper gets the result that Guangzhou would not be flooded for months like Bangkok did in 2011, but Guangzhou should gain enlightenment from Bangkok on flood control. The authors hold that flood control in Guangzhou should be comprehensive and prospective, and the influence of global climate change and urbanization should be considered thoroughly; drainage system in Guangzhou should be planned fitting the natural topography and the change of micro-landscape of the city; the drainage capacity and standard should be increased; and the drainage function of the wetland in the city should be reasonably used. In the paper, bringing the urban wetland into the flood control system is highly suggested.
