摘　　要：通过黑白瓶测氧法测定了香溪河库湾水体的临界层深度Z_(cr);同时根据测定的水下光照强度和透明度SD计算出3种不同的真光层深度Z_(1%),Z_(14)和Z-(2.7SD)。通过相关性分析,发现Z_(14)更能适应香溪河多变的天气和光照强度,在没有更好的计算方法之前,Z_(14)应是学者研究香溪河水库首选的计算方法。In this study,the critical depth of Xiangxi River Reservoir was determined by the dissolved oxygen bottle method of black and white.Simultaneously,using underwater lighting and transparency SD,described three different euphotic depth Z1%,Z14 and Z2.7SD.By correlation analysis,this paper found that Z14 can adapt to the changeable weather and light intensity in Xiangxi River.Before the better calculation method was invented,Z14 can be used as the preferred.
