环钦州湾河流入海污染物通量及其对海水生态环境的影响
Variation of River Pollutant Fluxes Around Qinzhou Bay and Their Environmental Impacts
摘要
Abstract
:Based on the investigative and statistical data obtained from 2001 to 2010,variations of river pollutant fluxes around Qinzhou bay were studied, and the correlation between river pollutant fluxes and socio-economic development around the bay during last ten years was analyzed. Also,the reasons and environmental impacts of river pollutant fluxes in the bay were discussed. Our results showed that river pollutant flux was the most part of the pollutant fluxes a-round Qinzhou bay and organic pollutant and nutrition dominated the pollutants. Total pollu-""tant flux varied from 2001 to 2005 and was steady during 2006^-2010. The variation of organic pollutant was similar to that of total pollutant while that of nutrition flux showed an increasing trend during last ten year. Fast socio-economic developments as well as pollutant treatments were main reasons for river fluxes variation during last ten years. The increasing of nutrition from river in recent years explained the increasing of nutrition concentrations and eutrophica-tion in the Qinzhou bay, which affected the ecological environment, such as algae bloom occurred in the bay, and the changes in community structure and diversity of phytoplankton.关键词
