摘要
在总结国内外关于水体自净规律研究的基础上,简述了影响水体自净的各种主要因素,选择水文、水质监测资料齐全的河段及库段,应用水质模拟方法,优选出水体耗氧系数K_1和复氧系数K_2,通过室内实验分析,求得实验条件下的K_1和K_2值,对比分析室内实验数据和野外监测成果,得出不同水体耗氧系数K_1及复算系数K_2的计算公式,可为生产实际服务。
he coefficient of water self-Parification plays a sigaificant role in aquatic enviroment assessement and water quality prediction models. The parameter K_1 is affected by many factors involving micro-organisms, temperature, water depth, water velocity, bed gradient, etc. This paper argues the concept of K_2 by experiment and field modelling. It also illustrates the other important parameter K_2, presents the empirical expressions of K_1 and K_2 applied to the southto-north water transfer middle routs.
