【摘要】：针对北方季节性河流环境流量短缺和污染并存的现状,从二元水循环的角度,提出一种建立在河流或河段的水量水质平衡基础上的环境流量分析方法;以典型重污染河流——贾鲁河为例,基于河流径流和水质特征,以满足水质目标要求为前提,提出保障环境流量的对策建议。结果表明:为改善河流近期水质,在提标治理和进一步严格监管的同时,基于2013、2014年数据,需新增环境流量分别为1.55m~3/s(折合0.49亿m~3/a)和8.10m~3/s(折合2.55亿m~3/a),其经济总成本分别为4.90亿、5.52亿元,占郑州市生产总值的0.08%,可依托现状引水工程进行保障环境流量水资源的调配,经济及水源途径可行。
[Abstract]:In view of the shortage of environmental discharge and the coexistence of pollution in seasonal rivers in northern China, a method of environmental flow analysis based on the balance of water quantity and water quality of river or reach is put forward from the viewpoint of dual water circulation. Taking the typical heavily polluted river-Jaru River as an example, based on the characteristics of river runoff and water quality, and on the premise of meeting the requirements of water quality, the countermeasures and suggestions for protecting environmental discharge are put forward. The results show that in order to improve the water quality of the river in the near future, in addition to raising the standard and regulating the water quality more strictly, based on the data of 2013 and 2014, the new environmental discharge is 1.55 mt3 / s (equivalent to 49 million mm2 / 3 / a) and 8.10 mm2 / 3 / s (255 million mm2 / 3a / s) respectively, and the total economic cost is 490 million, 552 million yuan, respectively. It accounts for 0.08% of the GDP of Zhengzhou. It can be used to ensure the allocation of environmental discharge and water resources depending on the current water diversion projects, and the economic and water sources are feasible.
