1998年汛期,由于嫩江流域的几条支流发生特大洪水,导致松嫩干流水位持续居高,江河横溢,泛滥成灾。洪水,给黑龙江省造成极大损失,也引起人们深刻的反省。通过考察,分析洪涝灾害成因,可以清楚地看到水土保持在防洪减灾中的重大作用。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。所谓水土保持,是指防治水土流失,保护、改良与合理利用山区、丘陵区和风沙区水土资源,维护和提高土地生产力,以利于充分发挥水土资源的经济效益和社会效益,建立良好生态环境的综合性科学技术。
In the flood season of 1998, due to the serious 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. Floods caused tremendous losses to Heilongjiang Province and caused profound introspection. By examining and analyzing the causes of flood disasters, we can clearly see the important role of soil and water conservation in flood control and disaster mitigation. 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 ignored in preventing floods and reducing sediment deposition in the rivers. The so-called soil and water conservation refers to the prevention and control of soil and water loss, conservation, improvement and rational use of land and water resources in mountainous, hilly and sandy areas to safeguard and enhance land productivity in order to give full play to the economic and social benefits of land and water resources and establish a good ecological environment Comprehensive science and technology.
