珠江口悬浮颗粒有机碳与环境因子的关系

RELATIONSHIPS BETWEEN SUSPENDED PARTICLES OF ORGANIC CARBON AND ENVIRONMENTAL FACTORS IN ZHUJIANG RIVER ESTUARY

本文应用逐步回归分析方法研究了珠江口悬浮颗粒有机碳与pH,Eh,盐度、化学耗氧量、硝酸氮、亚硝酸氮、活性硅酸盐的关系。由此得出的逐步回归的方程为 POC(μgC/L)=5527.06-667.56pH+9.71S影响悬浮颗粒有机碳的环境因子是pH和盐度。

Step regression analysis method is used for studying the relationships between suspended organic, carbon particles and POC, pH, Eh, Salinity, COD, nitrate and silicate in Zhujiang River estuary. The step regression equation used, isPOC(μgc/L) =5527.06-667.56 pH +9.71 SalinitypH and salinity are environmental factors influencing the suspended particles of organic carbon.
