摘　　要：滇中引水工程从丽江石鼓镇上游约1.5km的金沙江右岸大同村附近引水,最大引水流量135m3/s。为研究滇中引水工程取水对金沙江下游约47.8km的虎跳峡重要旅游景点虎跳石的景观影响,采用2015年对虎跳石全年每周连续拍摄的照片,分析虎跳石出现的不同景观特征及其水位,同时结合逐日水文资料提出虎跳石不同特征水位或特征景观下对应的流量量级范围。据此,分析长系列逐日的引水前、后各特征景观出现的天数及频率变化情况。研究结果表明:滇中引水工程引水后,并未改变引水前虎跳石出现的特征景观类别数量,引水仅改变了特征景观出现的时间和频率。The intake for Dianzhong water diversion project is located at about 1.5km upstream of Shigu town in Lijiang,right bank of the Jinsha river near Datong village,the maximum diversion discharge is 135m3/s.In order to study the impact of water diversion on the landscapes of the Tiger Jump Stone which is about 47.8km downstream of the Jinsha river,the authors used the photos taken every week throughout the year 2015 for Tiger Leap Stone,analyzed the different landscape features shown by Tiger Jump Stone and their corresponding water levels,and simultaneously proposed the range of discharge class at corresponding different characteristic water levels or characteristic landscapes for Tiger Jump Stone based on hydrological data measured daily.The authors accordingly also analyzed the number of days and frequency changes daily that every characteristic landscapes appeared under the condition of long series data before and after the water diversion.The results show that after Dianzhong water diversion project start using,the water diversion do not change the number of the characteristic landscape types before the water diversion,and it only changed the time and frequency of the characteristic landscapes.
