河流水质与流域人类活动之间的关系

河流水质状况受流域内的自然和人类活动这两大类因素的影响，其中，人类活动往往是导致河流水质恶化的主要因素，即水环境质量与流域内的各类人类活动密切相关。考虑到我国在这方面研究的还比较少，远不能满足水资源保护与水污染控制的迫切需要，本文从国外发表的大量研究成果中，选择介绍河流水质与几种典型的流域人类活动因素(人口、农事活动、土地利用结构等)之间的定量关系，并指出了需要进一步研究的问题，为我国的研究与实践提供借鉴。

Relationships between river water quality and human activities in watershed

River water quality depends on the natural characteristics and human activities in its watershed, in which human activities are main factors, causing serious water pollution usually. Therefore, there is close relation between water quality and human activities in its watershed. Considering there are few studies on this relation in China, which can't meet the urgent needs of water resources protection and water pollution control, several typical studies on the response of river water quality to population, agriculture and land use structure, from broad literatures are introduced. Finally, some further research needs are discussed briefly.
