| 中文摘要: |
| 本文以华北某农药类污染场地为研究对象,运用地统计学分析和GIS空间分析相结合的方法对研究区土壤中农药污染物的污染程度、污染物之间的相关性以及空间分布特征进行了研究。结果表明,研究区土壤中污染物组分P受母质、土壤质地等结构性因素影响,空间相关性强;对硫磷、甲拌磷、甲磺隆以及氯氰菊酯的空间相关性适中,人为因素贡献较大;研究区内农药污染严重,且污染程度、扩散方式与距离污染源的距离以及积水流动模式有关。 |
| 英文摘要: |
| Taking a pesticide contaminated site in North China as the research object and combining the methods of geostatistical analysis and GIS spatial analysis on soil pesticides, this paper studied the pollution levels, the correlations between pollutions and their spatial distribution characteristics.The results showed that soil contaminant component P in the study area showed a strong spatial correlation and was affected by structural factors, such as parent material, soil texture; parathion, phorate, cypermethrin, which showed a moderate spatial correlation. The artificial factor contribution is relatively big; pesticide pollution in the study area is serious, and the pollution levels and diffusion patterns are related to the distance from the pollution source and water flow pattern. |
