流域水文过程对湖泊酸化的影响—ILWAS模型在老虎岭水库的应用

APPLICATION OF THE ILWAS MODEL IN THE STUDY OF EFFECTS OF WATERSHED HYDROLOGICAL PROCESSES ON LAKE ACIDIFICATION IN LAOHULING RESERVIOR

应用美国ILWAS酸雨模型,研究了南宁市老虎岭水库流域在酸雨输入条件下流域水文过程,特别是入湖总径流的构成,对湖水酸碱状态和酸化进程的影响.结果表明,酸雨通过集水区土壤的流动路径是影响地表水酸化的最重要因素之一.

The ILWAS acid precipitation model was applied to study the watershed hydrological processes, the runoff composition and the effect to the lake acidification in the case research of Laohuling Reservior in Nanning City. The results indicate that the runoff flowpath from precipitation to the lake is one of the most important factors affecting the acidification rate of the surface water.
