摘要
本文根据 1995 年 9 月在南黄海获取的资料,分析和讨论了该水域浮游植物现存量(叶绿素 a ( C H ))、初级生产力( P P) 和海水光学参数(透明度( S T))、水色( W C)) 之间的相关关系。分析结果表明,夏末秋初南黄海 C H 与 P P, C H 与 W C 和 P P 与 W C 以及悬浮物( S S) 与 W C 之间均有良好的正相关关系。相关式分别为: P P = 22519ln( C H ) + 48891 或 P P = 5 E- 05 C H 16464( R2 = 07037); W C = 403ln( C H ) + 89768 或 W C = 71306 C H 04747 ( R2 =07921); C H = 15437ln( S S) + 13647 或 C H = 07499 S S1252( R2 = 07223); P P =33286ln S S+ 15222 或 P P = 33029 S S05694 ( R2 = 05476); P P = 42588ln( W C) - 37071或 P P = 66512 W C08665( R2 = 06731) 以 及 S S = 14019ln( W C) - 13363 ?
The correlations among phytoplankton biomass (chlorophyll a (CH)), primary productivity (PP), and seawater optical parameters (transparency (ST) and water color (WC)) were studied using the data obtained from the Southern Yellow Sea on September of 1995 Positive correlations were found between CH and PP, CH and WC and SS (suspended substance) and WC, where ln PP=225 19 ln (CH)+488 91(R 2=0 7037), ln WC=4 034 ln (CH)+8 9768(R 2=0 7921), ln CH=1 5437 ln (SS)+1 3647(R 2=0 7223), ln PP=332 86 ln SS+152 22(R 2=0 5476), ln PP=425 88 ln (WC)-370 71(R 2=0 6731) and ln SS=1 4019 ln (WC)-1 3363(R 2=0 9138). However, negative correlations were found between CH and ST,PP and ST, WC and ST and SS and ST, where ln CH=-1 5533 ln (ST)+4 7775(R 2=0 7035); ln PP=-278 2 ln (ST)+1039 6(R 2=0 757); ln WC=-6 5545 ln (ST)+22 531(R 2=0 8078) and ln SS=-2 3958 ln (ST)+7 0736(R 2=0 8459). This indicates that we can estimate phytoplankton biomass and primary productivity from seawater transparency and water color data respectively, and the correlation among the various parameters were analyzed.
