采用河网区非稳态水量数学模型,计算珠江东四口门1985-1995年的入海水量(净泄流量);在此基础上,利用1985-1995年在珠江东四口门每年至少3次(丰、平、枯)的实测水质资料(CODMn、BOD5、无机氮、水溶性磷酸盐、石油类等),计算1985-1995年间每年丰、平、枯三季从东四口门下泄到伶仃洋的污染物总量。利用经率定、验证的伶仃洋近海区二维非稳态水量、水质数学模型对珠江三角洲陆源污染通过东四口门下泄的污染物量、陆源污染物以及香港水域排污对伶仃洋水域的影响进行了研究。
Based on the mathematical model of unsteady water flow in the river network area, the water inflow into the sea (net discharge) from 1985 to 1995 in the east of the Pearl River Delta was calculated. Based on this, (CODMn, BOD5, inorganic nitrogen, water-soluble phosphates, oil, etc.) were calculated from the measured water quality data (abundance, flatness and dryness) Of the total amount of pollutants. Based on the two-dimensional unsteady water quality and water quality mathematical model of the offshore Dingding ocean area, the rate of pollution, the amount of pollutants released by the Dongsikou gate in the Pearl River Delta, the terrestrial pollutants, and the impact of sewage discharge in Hong Kong waters on the Lingdingyang Watershed Study.
