| 摘 要： | 从辽河生态系统基本特征出发,将辽河干流生态需水量分为生态基流量、稀释自净需水量、输沙需水量和蒸发量4个部分;通过6个重要水文断面实现生态需水分区;生态用水过程按汛期和非汛期分别计算;生态需水整合分为类型整合与分区内整合,类型整合中的消耗型需水采用累加原则,非消耗型需水采用取大原则,分区内整合在类型整合的基础上采用分区贡献法;最终建立了辽河干流生态需水分区分期整合计算模型。计算结果表明:辽河干流生态需水量在汛期以输沙需水量为主,非汛期以生态基流量为主;干流汛期和非汛期来水量不足,需要区间补给才能满足河道生态需水量。

| Abstract: | The ecological water requirement of the main stream of Liao River was classified as the ecological basic flows,the water requirement for self purification,water requirement for sediment transport and water consumption in evaporation.The subdivision of ecological water requirement was achieved by using six major hydrological sections.The ecological water utilization could be computed for flood season and non-flood season separately.The conformity of ecological water requirement of the main stream of Liao Riv... |
