摘要
由于人类为满足社会经济效益对天然河道的形态影响加剧,河道形态发生巨大改观的同时其天然行洪难以得到保障。在此背景下,选择河北张家口市崇礼区清水河流域作为中国华北地区山区行洪流域的典型区域开展调查实验,利用水文模型探究人工衬砌河道中天然行洪能否得以保障并发挥一定的经济效应。研究结果表明:人工衬砌河道中在辅以适当工程措施如消能坎后,能在一定程度上以不影响河道的自然功能下发挥社会经济效益,是一种可取的河道改造措施。
It is difficult to guarantee the natural flood discharge while the river form has been greatly improved.Under this background,Qingshui River Basin in Chongli District,Zhangjiakou City,Hebei Province,is selected as a typical area of flood discharge basin in the mountainous areas of North China to carry out investigation and experiment,and the hydrological model is used to explore whether natural flood discharge in artificial lining river could be guaranteed and play a certain economic effect.The results show that the artificial lining channel can give full play to the social and economic benefits without affecting the natural function of the river to a certain extent after being supplemented by appropriate engineering measures such as energy dissipation barrier,which is a desirable river course reconstruction measure.
