结果表明，鸭跖草等5种植物对重金属Cu、Pb、Zn、Cd、Cr都有程度不等的高量积累，尤其是铜元素，其最高积累量出现在海洲香薷根部，达到844.65 mg/kg，是一般植物Cu含量（5~25 mg/kg）的33.8~1689倍；而在同样条件下，As在5种植物体内的含量为018~098 mg/kg，远远低于As在一般植物中的含量（＜10 mg/kg），这说明这些植物对As可能具有某种规避机制。

Extreme climate elements such as torrential rain, extreme high temperature, extremely low temperature and so on are always used to analyze and evaluate an extreme climate event. There was a continuous sleeting and freezing process with low-temperature in the beginning of 2008. The process had the characteristics of large and sustained precipitation and snowfall, deep and long-time snow accumulation, long time in daily low-temperature with not so-low extreme low temperature. Therefore, it wasn't objective and accurate to choose any single one of these elements to analyze and evaluate this process.

评估极端气候事件，往往用某一项极端气候要素进行分析评估，如暴雨量、极端最高气温等。2008年初出现的持续低温雨雪冰冻过程，具有雨雪量大、持续雨雪时间长、积雪深、积雪时间长、低温持续时间长、但极端最低气温不低的特点，用其中任一因子评估定位该过程，都不能全面反映该过程的综合影响特征。
