摘　　要：选取甘肃省庄浪县的庙龙沟、榆林沟流域淤地坝为研究对象,通过积水面积、折减系数等指标,系统估算淤地坝工程蓄积的雨洪资源量,进一步估算淤地坝工程带来的水资源可利用量。结果表明:榆林沟和庙龙沟流域淤地坝工程雨洪资源的多年平均理论潜力、可实现潜力和现实潜力分别为2154.39万m^(3)、67.86万m^(3)、61.08万m^(3)和2796.28万m^(3)、88.08万m^(3)、79.27万m^(3);同时在50%频率下各流域淤地坝工程雨洪资源的理论潜力、可实现潜力和现实潜力分别为2131.61万m^(3)、67.15万m^(3)、60.43万m^(3)和2778.32万m^(3)、87.52万m^(3)、78.77万m^(3)。The silting dam in Miaolonggou and Yulinggou basins of Gansu Province was selected as the research object,and the stormwater resources accumulated in silting dam projects were systematically estimated through the indexes of water accumulation area and reduction coefficient,and the available water resources brought by silting dam projects were further estimated.The results show that:The annual average theoretical potential,realizable potential and realistic potential of stormwater resources for silting dam projects in Yulinggou and Miaolonggou are 623600 m^(3),678600 m^(3),808800 m^(3) and 561200 m^(3),610800 m^(3),792700 m^(3),respectively.At the same time,the theoretical potential,realisable potential and realistic potential of stormwater resources of the silting dam project in each basin at 50%frequency are 622100 m^(3),671500 m^(3),875200 m^(3) and 559900 m^(3),604300 m^(3),787700 m^(3),respectively.
