摘要
随着西北江三角洲自然环境的演变与经济社会的高速发展,无序的河道采砂导致河床严重下切。通过对近60 a的水文监测成果分析,利用水文统计学的方法,对河床演变趋势、分流分沙比、咸潮入侵等方面进行分析,发现自20世纪90年代中期以来,河流情势发生变化,多种水文要素发生调整,提出顺应自然规律的可持续发展治理理念,该研究对河道与堤围治理、防洪与供水安全、水资源管理都具有一定的参考价值。
With the Evolution of the Natural Environment and the Rapid Development of Economy and Society in the Northwest river delta,disordered river sand mining caused the river bed to cut seriously.Through the analysis of the hydrological monitoring results of nearly 60 years,the hydrological statistics method was used to analyze the river bed evolution trend,the split-sand-sand ratio,and the salt tide intrusion.It was found that since the mid-1990 s,the river situation has changed and a variety of hydrological elements have been adjusted.This paper proposes the concept of sustainable development governance in accordance with the laws of nature.This research has certain reference value for river and embankment management,flood control and water supply security,and water resources management.
