 note = {:In order to understand on characterstics of water quality of Chang Jiang，H uang Ho，T ai Hu and Dong Hu in People's Republic of China，c ontentsof Na ，K， Ca，M g，C l，S O.，a nd Si02 were determined. Water samples were collected from 3s tations in Huang Ho on August 1986 and 9i n Chang Jiang，2 i n Tai Hu and 1 in Dong Hu on August 1988. The water from Chang ]iang and Huang Ho were content three times higher in Ca and one-third lower in Si content than that ordinarily found in Japanese rivers. The Na and Cl contents were distinctly higher with waters from Tai Hua nd Dong Hut han from Chang Jiang，su ggesting the effect of human activities around the watershed of lakes. Using the key diagram based on cation :an ion equivalent ratio，wa ter types were studied. Of the waters from 17 stations，1 6 (1 in Huang .Ho excepted) were calcium -bicarbonate type which has the general quality of inland water. The water from the station in the lower stream of Hanung Ho was chracterizied as calciumnonbicarbonate type. This might reflect the dissolution of SO. from loess, Article, 環境科学年報11:131-139(1989)},
