| 摘 要： | 为阐明漳泽水库水环境要素的时空变化规律,依据历史资料和现场监测进行研究。结果显示,漳泽水库水环境要素年际分布的差异性较大,外源污染物的排放量是影响漳泽水库水质的首要原因。近10年来,漳泽水库水环境要素年际间均呈不显著的上升趋势,但月度变化差异较大;水质指标(BOD5、CODMn和DO)含量月度最高值出现在枯水期的2、3月份;7月份,DO和NH3-N处于最低值。TP在枯水期含量最低,平水期最高,丰水期则居中。温度、降雨量、蓄水量等因子的季节变化对水环境要素年内变化的影响比较显著。水温分层特性增强了水环境要素在垂向的分异性。

| Abstract: | The water environment variables of Zhangze Reservoir were surveyed monthly in 2007 to illustrate horizontal and vertical patterns of water environment.The results showed that interannual difference of water environment variable is significant,and the discharge of external pollutants was the first important factor.In the nearly decade,the concentration of water environmental parameters in Zhangze Reservoir assume a non-significant increasing trend year by year,and their monthly variations is also dramatic.Th... |
