调水工程河道内生态需水量研究及实例分析 吴春华 轩晓博 1 （黄河勘测规划设计有限公司，河南 郑州 450003） 摘要 __ 【】 生态需水的研究已成为国内外地球科学领域普遍的一个热点问题。南水北调西线 工程调水河流生态需水量的计算也是调水规模论证的基础。在对生态需水相关理论进行概括总结的基 础上，应用国内外较为成熟的水文学和水力学方法，对西线调水工程的河道内生态需水量进行了分析 计算，并根据南水北调西线工程调水区独特的生态环境保护目标，考虑主要保护两岸植被及河道内的 水生生物，且结果能满足维持河流生态系统健康的需要，选取针对性的方法对河流生态需水量进行了 分析与计算。结果表明：为满足不同保护对象对生态环境需水的要求，调水河段生态环境需水采用各 3333 364 m/s55m/s722 m/s40m/s 月生态环境需水的外包线，即～月为～，～月为～。河道内年均生 333 40m/s6m/s22.7m/s 态环境流量分别为：热巴，阿安、仁达、珠安达、霍那均为，洛若、克柯均为。 [关键词] __ 南水北调西线工程；调水河流；生态需水量 Study and case ____ysis on the Ecological Water De__nd in River Channels of Water division project Wu ChunHuaXuan XiaoBo Yellow River Engineering Consulting Co.Ltd., Zhengzhou,450003, Henan Abstract: The field of ecological water de__nd has been one of the research foci of geographical scien__s in the world. The calculation of ecological water de__nd in water exporting river of the first stage of western line from south to north water transfer project is the base of water transfer scale argumentation. Based on the sum__ry of ecological water de__nd theory research, we calculated the ecological river flow of water transfer project by ripe hydrology and hydraulics method. we also considered the need of keeping river system health and protecting the plants of side banks and the living things in river reaches according to the unique eco-enviro__ent of western route in water exporting region and the goal of enviro__ent protection. Then we selected counter methods to calculate the ecological water de__nd in river reaches. The results stated that the ecological water de__nd of water exporting river adopt epibolic various month ecological water. 3333 That is 4m/s55m/s from __rch to June and 2m/s40m/s from July to February respectively. ～～ 3 3-13-1 The yearly __erage ecological water is 40m/s for Reba6AanRendaZhuanda ，，， ms ms for 3-1 and Huona2.7Luoruo and Keke respectively. ， ms for Key words: The first stage of western line from south to north water transfer project; Water 1 2005037315 基金项目：中国博士后科学基金资助项目（） “” ；国家十一五科技支撑计划重大项目：南水北调 2006BAB04A08 工程若干关键技术研究与应用（） 作者简介 1970 ：吴春华（－），女，河南商丘人，博士后，副教授，主要从事环境生态学研究。 E-mail: wuchunhua88@126.com 1
