非氯盐型融雪剂在土壤中动态残留情况调查与分析

Investigation and Analysis of Non Chloride Snow Melting Agent's Dynamic Residual Cases

以非氯植物基融雪剂为试验对象,以沈阳机场高速公路和沈本高速公路绿化带为监测样地,研究非氯植物基融雪剂在土壤中的动态残留情况及对土壤肥力的影响。采用液相色谱法进行测定,运用Spss及Excel进行数据分析。结果表明:土层深度、距离、时间是影响非氯盐型融雪剂动态残留量的主要因素,作用力的大小顺序为时间>土层深度>距离;随着时间的增长、距高速公路边缘距离的增加、土层深度的加深,非氯盐型融雪剂在土壤中的含量不断减少,直至完全降解。

Taking non-chlorine plant-based snow melting agent as experimental subjects, Shenyang Airport Expressway and Shenben highway greenbelt green belt as monitoring sample plot, the paper researched the dynamic residual of non-chlorine plant-based snow melting agent in the soil and the changes of soil fertility. Liquid chromatograph was applied to determine, and the data were analyzed by SPSS and Excel. The results showed that soil depth, distance, time is the main factors affecting the dynamic residues of non-chloride snow melting agent, the impact order is timesoil depthdistance. With the increase of time, highway edge distance and soil depth, the content of non-chloride snow melting agent in soil decreased until the complete degradation.
