英文摘要:

Climate change and human activities are the two most important factors affecting water resource in Yellow River Basin, and Yellow River Basin is the most serious and prominent water shortage area in China. It is of great significance to study the impact of climate change and human activities on hydrology process in mountain areas of for water resources management. In this research, one typical watershed in the third sub region of the Loess Plateau was studied through the adoption of Zhang model. Water balance equations were established through analyzing the actual evapotranspiration from 1986 to 2016. Also, responses of evapotranspiration to climate change and LUCC were quantitatively distinguished as while. The results showed that the actual evapotranspiration was acquired by the method of water balance. During the Mann-Kendall test, the data could not produce sudden break. The actual evapotranspiration decreased along with the increase of the potential evapotranspiration. Comparatively, it increased to certain degree as the rainfall, relative humidity, temperature and wind speed increased while decreased with longer sunshine hours. Human activities played a dominant role in evapotranspiration variations, contributing approximately 90% to its change. Only 10% was contributed by precipitation factor. Large-scaled activities of the conversion from the sloping farmland to terrace were implemented in the middle 1980s in the studying Luoyugou watershed, remarkably influencing the regime of runoff generation and accordant junction. This is consequently leading to spatial-temporal variability in evapotranspiration.
