摘要
依据水环境功能区划分原则及技术方法对汉江干流地面水域的功能区进行划分。并采用野外观测及实验室分析相结合方法,利用汉江已有的环境观测资料和水文资料确定耗氧系数K1和复氧系数K2值。根据陕西汉江干流实际水文特点,建立了汉江有机质环境容量计算模型,最终对不同频率流量条件下的汉江有机质环境容量进行计算、分析。
The water environmental protection zones are partitioned according to the functions assigned to the sections of the mainstream of the Hanjiang River in Shaanxi Province. Combining the field observation and experimental data analysis, the degradation constant k 1 and reaeration constant k 2 are determined. A model is established with which the organic environmental capacity of the Hanjiang River under the condition of different flow frequencies are calculated and analyzed.
