| 摘 要： | 西江干流是珠江流域内最重要的鱼类产卵场分布区和鱼类洄游通道,其敏感生态需水可由控制断面的鱼类繁殖期适宜生态流量来确定。针对西江干流河道实际情况,选取迁江站和梧州站作为控制断面,依据西江鱼类产卵繁殖所需流速,采用生境模拟法估算西江干流迁江站、梧州站断面生态敏感期的适宜生态流量分别为1 722 m3/s、5 213 m3/s,敏感生态需水量分别为183亿m3、575亿m3,并利用Tennant法对计算结果进行了分析评价。该研究结果为西江干流的鱼类生境保护及水资源配置提供了技术依据。

| Abstract: | The main stem of Xijiang River is the most important fish Spawning location and migration channel in the Pearl River Basin.The sensitive ecological water demand is to be determined by the favorable ecological flow for the fish breeding at the control section.According to the specific situation of waterways in Xijiang River,the Xianjiang Station and Wuzhou Station are selected as the control section.According to the required velocity for the fish spawning and breeding,the hhabitat simulation method is used i... |
