珠江广州河段大气复氧能力的研究

Study on reacration in Guangzhou reach of Zhujiang River

通过现场观测和数值计算，获得了珠江员村及黄埔两河段大气复线系数的瞬时值、潮平均值和相应于稳态模型的等效值．结合珠江的特点，推荐了包括波浪影响在内的珠江广州河道复氧系数Ｋ２的计算关系式，Ｋ。的计算值与现场观测值符合较好．

Three reaeration coefficients in the Yuancun and Huangpu reaches of Zhujiang river i.e. the instantaneous value, the tidal averaged value and the equifinal value corresponding to the steady model were obtained by field measurements and processed by the numerical method in this paper. The computation formula for K2 in Guangzhou reach is recommended, in which the influence of wave on the reaeration is considered. The computation results of K2 are in good agreement with observed results. The reaeration coefficients in Guangzhou reach were estimated by the recommended formula for K2.
