根据目前的共识，随着温室气体继续在大气中积累，世界将在下个世纪变得更暖（见Levine，本卷第一章；Slade， 1990年）。大气环流型态的变化将导致气候的地理调整，从而影响区域和当地的水文循环，但影响的方式目前难以预测。例如，气候不同地区的降水可能变化±20%，径流可能变化±50% （Schneider et al., 1990）。气候的重大区域变化不仅会改变径流的数量，还会改变径流的变率和时间。由于许多生态过程受流量的数量和时间分布的调节，水文状况的重大变化可能导致淡水生态系统结构和功能的改变。
According to current consensus, the world will become warmer over the next century as greenhouse gases continue to accumulate in the atmosphere (see Levine, Chapter 1, this volume; Slade, 1990). Changes in atmospheric circulation patterns will lead to geographic adjustments in climate and thereby affect regional and local hydrologic cycles, but in ways that are currently difficult to predict. For example, precipitation in climatically distinct regions may change by ± 20% and runoff may change by ± 50% (Schneider et al., 1990). Substantial regional shifts in climate may alter not only the quantity of runoff but its variability and timing as well. Because many ecological processes are regulated by the quantity and the temporal distribution of streamflow, major alterations in hydrologic regimes are likely to result in modifications of freshwater ecosystem structure and function.
