今年汛期，由于嫩江流域的几条支流发生大洪水，导致松嫩干流水位持续居高，江河横溢，泛滥成灾。通过考察，分析了洪涝灾害成因，论述了水土流失造成生态环境恶化、加剧了洪涝灾害程度。说明了水土保持在防洪减灾中的重大作用。得出结论：解决水土流失问题，做好水土保持工作，是不容忽视的防洪和减少泥沙淤积江河的根本措施。并对今后水土保持工作提出了建议。
In the flood season of this year, due to the floods in several tributaries of the Nenjiang River basin, the water level of the Songnen River continued to be high and the rivers overflowed and flooded. Through the investigation, the causes of the flood disaster were analyzed, and the ecological and environmental deterioration caused by soil and water loss was discussed, exacerbating the degree of flood disasters. Explain the important role of soil and water conservation in flood control and disaster mitigation. It is concluded that solving the problems of soil and water loss and doing a good job of soil and water conservation are the fundamental measures that can not be neglected to prevent floods and reduce sediment deposition in the rivers. And put forward suggestions for soil and water conservation in the future.
