摘要: 桂南沿海流域地处祖国南部,南临南海北部湾,是广西农业及轻工业基地之一。粮食年产占广西总产量的20%,工业总产值占广西工业总产值的9%。沿海岸线曲折,港湾众多,建设发展中的北海港、防城港,是广西及我国西南地区的海上门户。随着沿海地区工农业生产的发展,生产及生活用水将不断增加,为合理开发利用有限的地表水资源,有必要对该区的地表水资源作一个正确的认识及评价。

Abstract: Water resource of the south coastal area in Guangxi have been preliminarily studied in this paper. Being about 50% of annual water amounts, the water amounts in summer have its largest values. The distribution of water resources. declines from east to west. At the Fangcheng city in Western Guangxi, the mean annual rainfall and the runoff depth amounts to 3000 mm and 2000 mm respectively, while the rainfall per squar kilometre is 2×106m3. It is one of theabundant water resources zone in China. Being rich in amount and fne in quality, the surface water resource of coastal zone in South Guangxi have been not fully used at present, therefore, it is bright prospects to exploit the water resource for productive activity. Ones have ever calculated that the supply of water resource is also adequate in the end of 20th century.
