芦苞涌与西南涌受闸影响入广州水量变化分析

广州虽属南方丰水地区,但本地的水资源量较少,时空分布不均,枯季径流明显不足。出于改善广州市水环境的目的,在枯季适当引入北江清水是关键措施之一。芦苞水闸与西南水闸建成后,减轻了洪水对广州市区的威胁,但同时也减少了北江通过两涌进入广州的水量,尤其是在平、枯水期,这一问题显得更为突出。对此在以往工作的基础上,分析进入广州的水量变化,为增加西南涌、芦苞涌的引水量,改善两涌沿岸的农田灌溉和水环境等提供参考。

Analysis on the Change of Water Volume Influenced by Water-gate Flow into Guangzhou through Lubao and Xinan Stream

Although Guangzhou is located in the southern moist area,the volume of local water resources is quite limited,the temporal and spatial distribution is non-uniform and the runoff is insufficient obviously in dry season.In order to improve the water environment of Guangzhou,drawing water from the North River appropriately in dry season is one of the most important measures.The completions of Lubao and Xinan water gate have reduced the threat of flood to Guangzhou urban district;however,they also reduced the w...
