摘要
在现有河道生态环境需水理论的基础上,结合平原河网地区城区河道的特点,分析了平原河网地区城区河道生态环境需水量的计算,并以南通濠河水系为例,计算了濠河生态环境需水量。结果表明:(1)平原河网地区城区河道生态环境需水主要用于维持河道的基本功能和结构,主要由河道基础水量和自净需水量两个部分组成;(2)河道的基础水量和河道级别紧密相关;(3)河流自净需水量与河道的纳污状况和水质目标相关密切。
According tO the theory of the environmental and ecological water requirements, the quantitative estimation of urban flows was made in view of the character of the urban flows. The Nantong urban river system was selected as an example. Its ecological water requirement was calculated. The results showed： （ 1 ） The environmental and ecological water requirements of urban flows mainly consisted of river fundamental water amount and water demand of river self purification in plain river system. It was mainly used to maintain the basic functions and structure of river. （2）The fundamental water demand of river had tight relationship with the type of river. （3） The water demand of river self purification had tight relationship with the ability of purifying pollution and water quality of river.
