珠江污染物入海通量规律研究

A study on Laws of Sea-going Pollutant Flux in the Pearl River

本文以成因分析方法,透过对水污染物入海通量各影响因子时空分布规律综合作用的研究,探索污染物入海通量的客观过程和相应的计算方法。对珠江流域陆上污染源的构成、分布、排放规律进行了较系统的宏观分析,结合珠江径流的时程变化规律讨论入海河口污染物实测浓度的时段代表性,并根据多年实测系列成果和专题监测成果,验算与分析目前年通量计算实用方法中时段划分对结果的影响,以及通量求解中存在的问题,也提出了珠江入海河口常规水质监测时机、频率,样品数量和分析方法、年通量计算应用公式、年通量评价等讨论意见。

A study on the comprehensive effect of distribution laws of contributing factors of sea-going pollutant flux in time and space was carried out by means of analysing its formation causes to explore its objective process and corresponding calculation methods. A systematic analysis of the formation, distribution and discharging laws of pollution sources on land in the Pearl River Valley was conducted. Opinions on the moment and frequency for conventional monitoring of water quality in outlets of the Pearl River, the quantity of samples and analysis methods, calculation formulas and assessment of annual flux were put forward.
