【摘要】 根据1987年2月～1988年2月的调查资料,研究了珠江口水域溶解氧与磷酸盐的相互关系。结果表明,5～7月和11月,底层AOU与PO₄-P之间高度显著相关,ΔP/ΔO摩尔比在1:102～1:216之间,平均值为1:149。3、5、8月和1988年2月,表层AOP与PO₄-P呈负相关趋势;而在1987年4、9、10、12月和1988年1月则呈正相关趋势。AOP与Chl-a高度显著相关。更多还原

【Abstract】 The relationship between dissolved oxygen and phosphate in the zhujiang River estuary is studied based on investigation from February 1987 through February 1988.The results showed there was a clear positive correlation between AOU and phosphate in bottom water in May,June,July and November,The mole ratio of AP/AO ranged from 1:102 to 1:216 with an average 1:149.In surface water a negative correlation between AOP and phosphate appeared in March,May,August of 1987 and February 1988,and a positive correlation in April September,October,December 1987 and January 1988.There existed a clear positive correlation between AOP and chlorophyll-a.更多还原
