英文摘要	Studies are critically needed to determine the effectiveness of soil and water conservation measures on both basin hydrology and soil erosion, and to assess whether the control measures put forth by governments arc achieving their stated goals. The comprehensive management of small, headwater watersheds is a particularly important means to control soil erosion. In this study, a distributed hydrological model was created for a typical small headwater watershed in the rocky karst desertification region of Guizhou Province to determine the impacts of soil and water conservation measures on basin hydrology. The results showed that: (1) recently conducted soil and water conservation measures led to an increase in total evaporation by 1.55% from 2015 (prior to watershed treatments) to 2017 (following watershed treatments). Changes in evaporation were accompanied by a decrease in basin runoff, an increase in water storage, and an improvement in available water in the small karst basin by 17.84% following the implementation of the measures; and (2) after the implementation of recent soil and water conservation measures, the evaporation capacity of the watershed during a wet year increased by 1.00%, the runoff decreased by 10.00%, and the total amount of soil water storage increased by 5% compared with those before implementation. During an average year, the evaporation and water storage in the watershed increased by 1.28% and 5.73%, respectively, whereas the runoff decreased by 7.10%. Soil water consumption and water storage of the watershed increased, significantly reducing flow. The scientifically based assessment conducted herein provides significant insights for correctly guiding ecological construction in karst watersheds. It also fulfills an objective requirement of the water and soil conservation management department to improve the level of water and soil conservation planning and decision-making.
