摘　　要：对贵州省猫跳河生态累积效应进行评价.以修文水库为例,采用RVA方法分析该站的日流量数据和IHA水文指标,剖析该河流的生态累积效应情况.研究结果表明:建坝后猫跳河流量的历时和频率等指标变化较大,极端流量事件的持续时间减少,说明建坝对该河流的中下游生态产生了较显著的影响.The construction of reservoirs will change the hydrological regime of natural rivers,thus threatening the river ecosystem.Based on the middle reach Xiuwen reservoir,the study analyzed the daily flow data of the station,calculated 32 IHA hydrological indexes,and calibrated the changes of different indexes,thus analyzed the ecological accumulation effect of the river.The results show that the overall hydrological situation of Maotiaohe river changes greatly after damming,among which the indexes such as duration and frequency of flow change the most,and the duration of extreme flow events decreases,indicating that damming has a significant impact on the ecology of the middle and lower reaches of the river.
