调查了青草沙库区内外2010年7月～2011年2月的UV254变化规律,重点考察了青草沙库区内外UV254空间分布,库内监测点UV254的季节性变化规律,以及高低平潮位对库外监测点的影响.结果表明,监测期库内外水质总体较好,UV254在0.03～0.07cm-1之间波动;不同季节,不同潮位,UV254随采样点空间变化明显.%UV254 Distribution inside and outside waterbody of the Qingcaosha Reservior was investigated during the time period of July, 2010 to February, 2011. The study focused on spacial and seasonal distribution of UV254 inside the reservior, and the effects of tides on UV254 monitoring results outside the reservior. Results showed that UV254 value both inside and outside the reservior was in the scope of 0.03～0.07 cm-1 during the investigation period implying a good water quality and, UV254 changed significantly with the sampling space in different seasons and tidal levels.
