摘　　要：本文根据河道径流特性与地形地貌特征的关联,首次把南四湖流域分成3个径流区域进行系统研究,分析了区域内多年水资源量平衡。重点研究了区域天然径流的形成机制,推求出地理和气候条件下径流量的变化规律。探讨提出了区域内河流生态径流量的评价方法,为水环境保护提供了数据支撑。According to the correlation between the runoff and landform characteristics, the Nansihe Lake basin has three types of runoff forming. This paper did a system investigation for all of them, and analyzed characteristics of the water resources balance. Special attention was paid to mechanisms of the natural runoff forming and impact of geographical and climatic factors on the river runoff. It also discussed the methods for estimation of the stream ecological runoff in the region.
