Other AbstractThis study was conducted to analyze the variation characteristics of carbon and nitrogen contents in water during the growing season in an alpine grassland watershed in the Tibetan Plateau. The results show that the dissolved carbon (DOC), dissolved organic nitrogen (DON), ammonium nitrogen (NH_4~+-N)and nitrate nitrogen (NO_3~--N) concentration in water of the alpine grassland watershed are respectively 2.95 -6.96mg·L~(-1), 0.45-1.15mg·L~(-1), 0.02-0.88mg·L~(-1) and 0.16-0.36mg·L~(-1). DOC, DON and NO_3~--N increased to a peak in the middle of September and then decreased, however, NH_4~+-N had no significant seasonal variation characteristics. The dissolved nitrogen concentration is DON >NO_3~-N >NH_4~+-N. Precipitation, soil temperature at 20, 40,60,90, 120cm depth, and soil moisture at 10,20,40,60cm depth have significant positive correlation (P<0.001) with DOC and DON contents in the water. There is a significant positive correlation (P<0.05) between NH_4~+-N and precipitation, air and water temperature. The NO_3~--N has a significant positive correlation with precipitation.
