沋河水质空间分布特征研究
|
摘要
对渭南市沋河水库及以上河段、沋河公园、沋河下游河段布点采样,分析其水质空间特点。研究发现:浊度和溶解氧指标空间特点都表现为水库以上河段数值低、波动小,均值分别为12.78 NTU和7.18 mg/L;公园及以下河段浊度高、波动大,分别为38 NTU和32.88 NTU;公园河段溶解氧数值高、波动大,均值为12.39 mg/L,下游溶解氧降低;总硬度在公园以上河段数值较高,波动不明显,但公园以下河段则表现为剧烈波动,平均值分别为5.22 DH和7.41 DH。研究证明沋河各河段水质变化以水库至公园为突变点,这一河段的水质维护极为重要。
The article analyzed the water quality spatial characteristics of the Weinan Youhe River Reservoir and its upper streams,the Youhe River Park,and the downstreams of Youhe River. The results showed that the spatial characteristics of turbidity and dissolved oxygen were small fluctuations in the upper water of reservoirs. The averaged turbidity and dissolved oxygen concentration were 12. 78 NTU and 7. 18 mg/L respectively. The park and the following reach were high in turbidity and fluctuation,which were respectively 38 NTU and 32. 88 NTU. The concentration of dissolved oxygen in the park was as high as 12. 39 mg/L,and larger than that in the downstream. Total hardness of water in the park above the numerical value was high and the fluctuation was not obvious. However,water hardness in the park and the following reach were characterized by obvious fluctuations,which were 5. 22 DH and 7. 41 DH. The results indicated that the water quality of the Youhe River basin has been greatly changed between the reservoir and the park,which was a very important section for the water quality maintenance.
