英文摘要	Semi-arid area refers to the area where the precipitation is between 200-400mm and the annual mean evaporation is more than 1000mm. Because of insufficient rainfall that could not support the growth of vegetation, groundwater becomes an important replenishment to the ecological water demand of vegetation. Thus, research on the critical depth of groundwater recharge for vegetation in semi-arid areas is critically important to ecology. This paper mainly analyzed the basic principles of groundwater recharge for vegetation in semi-arid areas and deduced the theoretical calculation formula, which was quantitative calculated, of the critical depth of groundwater recharge for vegetation. The study selected Ordos, Xilingol, Hulunbuir and other semi-arid areas and conducted calculation and application. The conclusion was that the critical depth of groundwater recharge for vegetation in Hulunbuir City and Xilinhot City was 1.5 similar to 3.5m, with an insignificant difference, while the critical depth in Ordos was 3 similar to 5m, mainly related to vegetation types and soil types.
