广州市水浸街的原因及缓解方法之探讨

摘要

In recent years, more and more places become flooding easily, especially after a heavy rain. The reasons cause this phenomenon can be roughly divided into two categories, which are the natural factor and man-made fac- tor. One of the major points in the man-made factor is the construction of drainage system in Guangzhou City. To ef- fectively control flooding phenomenon, it needs to expansion and repair its current drainage network. However, the existing situation in Guangzhou City, not only the transformation space is relatively limited, but also supplemented by other ways to alleviate the pressure on the drainage pipe network. This study provides how the drainage network influence the floodin~ phenomenon and summarizes the solutions.%近几年广州市水浸黑点越来越多，个别黑点甚至逢雨必浸，导致水浸街现象频繁出现的原因大体可分为自然因素和人为因素两大类．人为因素中主要体现于广州市排水系统的建设相对于广州市城市化的发展滞后。要有效地控制水浸街现象出现，需要对排水管网进行扩建和修补，但现时对广州市排水管网的改造空间相对有限，因此还要辅以其他的方式，减轻管网的排水压力。本文简要地对因排水管网引起水浸街现象的原因及缓解方法进行分析总结。
