According to the cross-section survey data of the riverbed in the reservoir area , the coming sediment is calcu-lated by back calculation method .The sedimentation tend of Huanglongtan Reservoir is judged by analyzing the delta deposition body and the influence of the construction of Pankou Hydropower Station in the upstream .Results show that the sedimentation does not affect the life of the reservoir and the flood control standard .% 依据库区河床横断面测量数据，用反算法计算来沙量；通过对三角洲淤积体的分析和上游潘口水电站兴建后的影响，判断黄龙滩水库泥沙淤积趋势。经分析认为，淤积泥沙不影响水库寿命和防洪标准。
