In addition, δ18O and nutrients concentrations of water samples in Zhalong Wetland at Heilongjiang Province in China were also determined.Consequently, the following matters have been mainly clarified. (1) δ18O values of sample waters in Zhalong Wetland are generally large probably because of the effect of evaporation, whereas those of Sakata lagoon are large which may be due to the biological process such as the activity of plankton. (2) Considering the results of nutrients concentrations, the water quality of lagoon (Sakata and Toyanogata) waters in Niigata Prefecture is better than that of Zhalong Wetland in China.}, pages = {409--421}, title = {新潟県の湖沼における水質及び同位体的特徴 : 中国黒竜江省のZhalong湿地との比較も含めて}, volume = {62}, year = {2013} }
