我国江河治理与泥沙研究展望

Outlook on River Regulation and Sediment Research

水资源和泥沙的不均匀分布，特别是北方河流的泥沙问题，使我国江河治理的工作异常复杂，江河治理工作必须结合考虑水资源、泥沙和环境等方面的因素． 人类剧烈活动对河流的来水来沙过程产生了重要的影响，使河床演变规律发生了巨大的变化． 提高江河治理工作中的科技含量，加强江河治理中的科技创新，将是 21 世纪我国江河治理与泥沙研究中科技发展的趋势，主要反映在以下几方面：（1）泥沙作为环境问题的一个重要组成部分，研究泥沙与区域环境演变及其治理；（2）将泥沙作为一种资源，研究水沙资源综合利用与调控；（3）人类剧烈活动影响下的河床演变、河道整治及工程泥沙研究；（4）加强学科交叉和高新技术应用的泥沙基础理论研究．

： The non-uniform time and spatial distribution of water resources and sediment makes the river regulation extremely complicatedespecially for the rivers in the north of China． It is necessary to consider the factors of water resources sediment and environment altogether． Increasing scientific and technological percentage and developing new methods for river engineering will be the main tendency in next century． Thus this paper focused on（1） Considering sediment as an important part of environmental problem the evolution and treatment of sediment and regional environment are studied （2） Considering sediment as a kind of resources the integrated utilization and control of the water－sediment resources is involved．（3） Taking into account the influence of mankind activitiesthe river processes and regulation and sediment engineering is discussed． And also（4） Resorting to the inter-science and hi-tech tool the basic theory of sediment transport will continuously be emphasized．
