| 摘 要： | 应用改进的集水区地下水酸化模型（ＭＡＧＩＣ）对四川境内长江支流沱江的主要离子含量变化趋势进行模拟．在只考虑酸沉降和土壤化学过程的情况下，模型模拟结果与沱江李家湾站１９７２—１９９０年测定的主要离子含量的变化趋势吻合，初步认为酸沉降是导致沱江主要离子含量变化的主要原因． |
| 关 键 词： | 长江 水质变化趋势 MAGIC模型 酸沉降 |

| Abstract: | The evolution trend of major ion contents of Tuojiang,a tributary of Yangtze river,was simulated with the applicatioin of modified MAGIC (model of acidification of groundwater in catchment).Acid precipitation and chemistry process in soil were taken into account in MAGIC.The simulation results were consistent with the monitoring data of major ions at Lijiawan Hydromotric Station of Tuojiang from 1972 to 1990.It was concluded that acid deposition is the main cause of water quality trend of Tuojiang. |
| Keywords: | Yangtze River water quality trend MAGIC acid precipitation |
