为保护和恢复河流生态系统健康,本文通过河流不同流量形态的生态意义的分析,探讨了生态流量的内涵及其谱系结构,将生态流量谱系划分为极低流量、低流量、高脉冲流量、高流量、极高流量五种流量形态。
4) ecological basic flow
生态基流

As the wetted perimeter method has the subjective shortcoming in determination of the inflection point, however, the method of maximum can determine river ecological basic flow objectively to avoid the subjectivity concerned, the probability distribution of river ecological basic flow is then studied on the basis of the wetted perimeter method.
由于湿周法在确定突变点中存在主观性的缺陷,而最大曲率法可客观的确定河流生态基流,避免了主观性。
5) basic ecological flow

【Result】The result of the calculating case shows that the basic ecological flow compensation benefits were 28.
【结果】2003年黄河龙羊峡和刘家峡梯级水库对花园口站非汛期的生态基流补偿效益为289。
6) base ecological flow in non-flood season
非汛期生态基流量
1.
Based on the unique characteristics of the Yellow River and previous research on its ecological water requirement, the present paper recommends that the water requirement for transport in the flood season and base ecological flow in non-flood season should be both included in the ecological water requirement.
通过分析黄河下游1958~2000年实测生态可用水,探讨生态需水量内涵,根据黄河特殊性及黄河生态需水量的研究现状,将维持和保护河流功能的黄河下游生态需水量分为汛期输运水量和非汛期生态基流量,在平滩流量输运能力最强的前提下,估算黄河下游汛期输运水量为80~120亿m3,根据实测资料估算作为黄河下游水量控制断面花园口水文站和作为河口地区水量控制断面利津水文站的非汛期生态基分别为80~100亿m3和50~60亿m3。
补充资料:生态基
生态基是一种新型的人工水质修复和维护的方法。它是一种经过处理的适合微生物生长的“床”,也就是一种新型生物载体(填料)。
生态基一旦放置于水中,立即会吸附水中各种水生生物到其表面,随着时间的推移生态基表面会附着生长微生物和藻类,这些微生物和藻类对于富营养化水体起到生物过滤和生物转换的关键作用。附着在生态基上的微生物相非常丰富,主要由细菌、真菌、藻类、原生动物和后生动物等构成复杂的生态系统。微生物体系通过自身的新陈代谢分解水中的有机物,生态基上生长的微生物可吸附水体中的富营养成分,如氮、磷、硫、碳等物质,并将这些富营养成分富集,通过不同的微生物作用,转化成为富含蛋白质、氨基酸、维生素、类胡萝卜素等的物质,这些物质成为水生动物的食物。从而夺取了蓝绿藻生长所需的营养物质,抑制了蓝绿藻的滋生,水质逐渐得到改善。
