摘要
测定了珠江13个采样点在2009年9月至2010年8月期间的15个水质指标。结果表明,在研究区域内,水质类型可以分为5类,以Ca-HCO3型水为主;水质类型主要受到水与地质岩石矿物相互作用的影响,SO4型、Cl型和Na型水质分别与硫铁矿矿山、海水潮汐和人为活动有关;受海水潮汐影响的Na-Cl型水质中,溶存物质以及重金属的量均较其他水质类型高。
15 water quality indicators of water samples collected from 13 collection areas in Pearl River during the period September 2009 to August 2010 are tested. The results show that the water quality of the studied areas can be classified into 5 categories, among which Ca - HCO3 water is the dominant one; water quality type is mainly affected by the interaction be- tween water and minerals in geological rocks and SO4 type, C1 type and Na type water is related to pyrite mine, sea tide and human activities respectively; the amounts of dissolved substances and heavy metals in Na - C1 type water affected by sea tide, are higher than those in other types of water.
