地表水水质影响因素研究进展

Advances in Influencing Factor on Surface Water Quality

指出了随着现代社会经济的快速发展及人民生活水平的不断提高,某些国家或地区的地表水水环境质量不断恶化,有关水质变化的问题已成为政府及国内外科学家关注的重点。在参考国内外有关地表水水质影响因素研究成果的基础上,阐述了自然环境因素(气候、水文特征、水生生物等)和人类活动因素(社会经济发展、土地利用景观格局、水利工程建设等)对地表水水质的影响,研究发现:不同地区水质的影响主控因素不同,某些地区的水质同时受到多种因素的影响。因此,在进行水质改善及水资源保护时要有的放矢,明确影响水质的主控因素。

With rapid development of economy and people’s living standards,the surface water environment in some areas have been deteriorating.Issues related to water quality changes have aroused great concerns among scientists and politicians at home and abroad.And exploring the reasons for changes in water quality is more urgency.Based on referencing to the domestic research results of the surface water quality’s influencing factors,this paper summarized the impact of natural environmental factors（climate,hydrological characteristics,aquatic organisms,etc.）and human activity factors（socio-economic development,land use and landscape pattern,hydraulic engineering construction,etc.）for domestic surface water quality.We could see that：the water quality in different regions could be affected by different factors,and in some areas it was affected by many factors simultaneously.So it should be targeted during water quality improvement and protection of water resources,and knowingclearly the main reason wasimportant.
