气候和土地利用的变化影响水文循环，导致集水区产水量和径流特征的变化。了解气候和土地利用变化对水的综合影响对于制定可持续的水资源计划至关重要。大多数研究只考虑单独或单独考虑气候或土地利用的孤立影响，这可能会扭曲水文反应的图景，因为对气候或土地利用变化的重要性太少或太多。量化气候和土地利用变化的综合影响是一项重大挑战，因为产水量是这两个因素的叠加。本文简要回顾了有关量化气候和土地利用变化对产水量影响的主要文献，重点介绍了过去十年发展起来的框架。我们讨论了框架中嵌入的假设，以及预测气候和土地利用对未来产水量的影响的可能性。
Climate and landuse change impact the hydrologic cycle resulting in changes in catchment water yield and streamflow characteristics. Understanding the combined effect of climate and landuse change on water is essential for developing sustainable water resources plans. Most studies consider only the isolated effect of climate alone or landuse alone, and this could skew the picture of hydrologic responses by attributing too little or too much importance to climate or landuse change. Quantifying the combined impact of climate and landuse change is a significant challenge as water yield is the convolution of both these factors. This paper briefly reviews key literature on quantifying climate and landuse change impacts on water yield with an emphasis on the framework developed over the last decade. We discuss the assumptions embedded in the framework and the potential for predicting climate and landuse impact on future water yield.
