Study on the Relationship between Contamination Distribution and Sampling Density

摘要

Use some contaminated site (D-block) in Chongqing of China as the experiment site, this paper studies effects of different sampling density (layout grid spacing) on the contaminated area and determination of contaminated boundary in system layout method of environmental monitoring, and then discusses the relationship between sampling density and contaminated distribution in system layout method according to the experiment result. The experiment result indicates that: in a certain range, increase the sampling density, contamination distribution will be more accurate; too big sampling density is not practical; for the common sites with unknown or large-range contaminated distribution, 10m×10m is the recommended layout sampling density.
