摘　　要：汉江水环境状况对襄阳市和汉江中下游的社会经济发展及人民生活影响重大。崔家营航电枢纽工程建成运行后,汉江襄阳城区段成为崔家营库区,形成水库型河流。引入湖泊入出湖污染物通量的计算公式,通过同步监测2017年汉江襄阳河段干支流水质水量,估算了汉江襄阳河段不同水期的污染物通量,分析出入江污染物通量随时间的变化及空间来源组成。结果表明:2017年汉江襄阳河段污染物通量主要来自丰水期,丰水期入江污染物通量空间分布与年通量分布一致。入江通量大于出江通量,各监测断面水质与水量多呈正相关。汉江襄阳河段的污染物控制应以强化主要入江河流输入通量控制为主,尤其是丰水期的污染物防治工作应作为水环境保护的重点。Water quality of the Hanjiang River is important to economic and social development as well as people's living conditions in the middle and lower reaches.After completion of Cuijiaying Navigation and Power Hub Project on the Hanjiang River and its reservoir started impounding,the Xiangyang section of the Hanjiang River became the Cuijiaying Reservoir Area,and formed a reservoir-type river.By employing the calculation method for pollutant in⁃flux and outflux of the lake and based on hydrological and water quality data of the Xiangyang section in 2017,the main pollutant influx and outflux of the Hanjiang River in different seasons were estimated.Furthermore,temporal variations and sources of pollutant flux were analyzed.The results showed that in 2017,most of pollutant influx in the Hanjiang River came from the wet season;its spatial distribution was consistent with the annual distribution.The pollutant influx was greater than the outflux,and there were positive correlations between the water quantity and water quality for every monitoring cross-sections.The key to pollution control in the Xiangyang section is control⁃ling the pollutant influx from the upstream river.In particular,the prevention and control of pollutants during wet season should be prioritized in terms of water environment protection.
