文中在综合国内外有关河流系统生态环境需水研究的基础上,以桑干河为例,探讨了河道内生态环境需水量的内涵及组成,并从生态基流、自净需水量及输沙需水量三个方面对河道内生态环境需水量进行了研究。
On the basis of synthesizing the relevant studies of river system eco-environment water demand at home and abroad, the paper explores connotation and composition of instream eco-environment water demand, and taking Sanggan River as an example, researchs from three parts of basic ecological water demand, self-purification water demand, sand transport water demand.
