黄河与海河的泥沙一直是人们所关注的问题。1984年9月,我应邀参加中国水利学会组织的河流泥沙和水土保持考察,目的在于了解人类活动对来沙的影响,评价现有各项水利水保措施的减沙效果,并预估其未来的发展,为流域治理服务。另外通过调查,了解一批减沙效益较明显的水利水保措施,分析怎样用综合措施来进行治理,达到控制水土流失的目的。
The sediment of the Yellow River and Haihe River has always been a concern. In September 1984, I was invited to participate in the investigation of river sediment and soil and water conservation organized by China Hydraulics Society. The purpose is to understand the impact of human activities on sediment yield and assess the effect of various water conservancy and soil conservation measures on sediment reduction. Future development, service for basin management. In addition, through investigation, we can understand a number of water conservancy and soil conservation measures that have obvious benefits in reducing sediment yield, and analyze how to use comprehensive measures to control so as to achieve the purpose of controlling soil and water loss.
