为研究重庆地区长江和嘉陵江江水的水温、水质、水位的年变化规律,开展了全年逐月测试。结果显示,两江水温在竖直断面上基本保持不变,相对于嘉陵江而言,长江江水温度具有夏季较低、冬季较高的特点,较嘉陵江更适合作冷热源;两江江水均要解决浊度大的水质问题,长江江水还须解决铁离子含量偏高的问题;重庆地区两江的水位变化幅度分别约为3.8,5.4m,且变化频繁。
In order to study the annual variation law of water temperature, water quality and water level in the Yangtze River and Jialing River in Chongqing area, a month-by-month test was conducted. The results show that the water temperature of the two rivers remains basically unchanged in the vertical section. Compared with the Jialing River, the Yangtze River water temperature has the characteristics of lower summer and higher winter, more suitable for cold and heat sources than the Jialing River; Degree of water quality problems, the Yangtze River also have to solve the problem of high iron content; Chongqing two water level changes were about 3.8,5.4m, and frequent changes.
