摘要
2010年10月,长江水利委员会组织了第三次长江源考察,为了对长江源区水资源、水环境、水生态等方面进行综合性分析,在长江源典型代表区进行了实地采样分析。根据水样分析成果,并结合相关资料,对水体和沉积物中物理、化学元素含量及分布规律进行了归纳和总结。总体来说,长江源地区水体基本处于天然状态,尚未受到有机物污染或有机物污染程度非常低,水环境状况主要受地理、气候、降水等因素影响。
In October, 2010, Changjiang Water Resources Commission organized the third investigation on the sources area of Yangtze River. In order to comprehensively analyze the water resources, water environment, water ecology etc. , in - site samples were taken in typical area of the sources area of Yangtze River. Based on water sample analysis results and combined with correl- ative data, the physical and chemical element content in water and sediment and their distribution law are summarized. In gener- al, the water in the sources area of Yangtze River is in natural state, which is not polluted by organic matter or the organic pollu- tion is slight ; the water environment is mainly influenced by geography,climate and precipitation etc.
