Urban water bodies play a vital role in maintaining the urban environment and development. In order to solve the problem of low transparency of its water body, taking Yaojiang River as the research object, the effects of solar radiation, turbidity, suspended solids concentration and particle size on water transparency were analyzed by means of comparative ratio, Pearson correlation analysis, and curve fitting calculation. The results show that the light intensity, solar elevation angle and azimuth angle affect the transparency monitoring. The stronger the light is, the greater the monitoring result of transparency is. Transparency (SD) is negatively correlated with turbidity (TUB) and suspended solids concentration (SS). Pearson correlation coefficients are -0.880, -0.570. After monitoring and calculation, the median particle size (d50%) of Yaojiang River is between 15.5 and 61.3 μm. Filtration through a filter with a pore size of 10 μm can control the turbidity of the water body within 9.7 NTU and the concentration of suspended solids within 13.4 mg/L. The transparency of the Yaojiang River can reach 80 cm, which is the minimum requirement to maintain a normal aquatic environment.

城市水体对维持城市环境和发展具有至关重要的作用,为解决城市水体透明度较低的问题,采用对比求比值、Pearson相关性分析、曲线拟合计算等方法,分析了宁波市姚江太阳辐射、浊度、悬浮物浓度及颗粒物粒径对水体透明度的影响。结果表明,光照强弱及太阳高度角、方位角会影响透明度的监测,光线越强,透明度监测结果越大;透明度(SD)与浊度(TUB)、悬浮物浓度(SS)均存在极显著负相关关系,Pearson相关系数分别为-0.880、-0.570。经监测和计算,姚江的颗粒物中值粒径(d50%)介于15.5~61.3 μm之间,通过10 μm孔径的过滤器进行处理,可使水体的浊度控制在9.7 NTU以内,悬浮物浓度控制在13.4 mg/L以内,此时姚江透明度可达到80 cm,是维持正常水生环境的最低要求。

城市水体对维持城市环境和发展具有至关重要的作用,为解决城市水体透明度较低的问题,采用对比求比值、Pearson相关性分析、曲线拟合计算等方法,分析了宁波市姚江太阳辐射、浊度、悬浮物浓度及颗粒物粒径对水体透明度的影响。结果表明,光照强弱及太阳高度角、方位角会影响透明度的监测,光线越强,透明度监测结果越大;透明度(SD)与浊度(TUB)、悬浮物浓度(SS)均存在极显著负相关关系,Pearson相关系数分别为-0.880、-0.570。经监测和计算,姚江的颗粒物中值粒径(d50%)介于15.5~61.3 μm之间,通过10 μm孔径的过滤器进行处理,可使水体的浊度控制在9.7 NTU以内,悬浮物浓度控制在13.4 mg/L以内,此时姚江透明度可达到80 cm,是维持正常水生环境的最低要求。

Urban water bodies play a vital role in maintaining the urban environment and development. In order to solve the problem of low transparency of its water body, taking Yaojiang River as the research object, the effects of solar radiation, turbidity, suspended solids concentration and particle size on water transparency were analyzed by means of comparative ratio, Pearson correlation analysis, and curve fitting calculation. The results show that the light intensity, solar elevation angle and azimuth angle affect the transparency monitoring. The stronger the light is, the greater the monitoring result of transparency is. Transparency (SD) is negatively correlated with turbidity (TUB) and suspended solids concentration (SS). Pearson correlation coefficients are -0.880, -0.570. After monitoring and calculation, the median particle size (d50%) of Yaojiang River is between 15.5 and 61.3 μm. Filtration through a filter with a pore size of 10 μm can control the turbidity of the water body within 9.7 NTU and the concentration of suspended solids within 13.4 mg/L. The transparency of the Yaojiang River can reach 80 cm, which is the minimum requirement to maintain a normal aquatic environment.
