Abstract:: In order to reveal the relationship between ecohydrological processes and climate change, the artificial bamboo forest in typical watershed of Mao'er Mountain, Guangxi Province was used as the research object. The Hydrus-1D model was used to simulate the soil moisture and other hydrological elements of the bamboo forest. Different climate change scenarios were set to analyze the response of the artificial bamboo forest to climate change. The results show that the Hydrus-1D model is suitable for the ecohydrological analysis of the artificial bamboo forest; the evapotranspiration of the artificial bamboo forest accounts for 28.40% of the total precipitation, and the runoff is mainly base flow; under different climate change scenarios, the increase of evaporation and transpiration is controlled by the increase of temperature, and the increase in winter is greater than that in summer; runoff was more sensitive to changes in precipitation; changes in precipitation affect summer runoff more, while temperature is more likely to affect winter runoff; precipitation has more influence on soil water storage in summer than in winter, while temperature has more influence on soil water storage in winter; under the condition of coupling with temperature and precipitation, soil water storage is most sensitive to the decrease of precipitation and the increase of temperature, and the soil water storage overall is more obviously affected in winter. These results can provide reference for regional ecological planning and water resources development and utilization.
