美东地区的罗德河流域遭受着严重的酸沉降侵蚀．在酸性条件下，铝从土壤中大量溶解并迁移到水环境中．地表水中升高的铝浓度对鱼类产生毒害，监测地表水和土壤水中的铝形态及浓度变化已成为问题的关键．本文报导了用化学平衡模式计算法分析美东地区罗德河流域地下水中的铝形态分布，获得了有价值的结论 The Roode River basin in the eastern United States suffers severe acid deposition erosion. Under acidic conditions, aluminum dissolves largely from the soil and migrates into the water environment. Aluminum concentrations in surface waters are toxic to fish and monitoring the changes in aluminum form and concentration in surface and soil water has become the crux of the problem. This paper reports the analysis of the distribution of aluminum species in the groundwater in the Roode River Basin in the eastern United States using the chemical equilibrium model method, and draws valuable conclusions
