The Setting of Cut-Off Point for key Industrial Polluting Source Investigation
The principle and method for setting cut-off point in key industrial polluting source investigation are discussed, and empirical research is carried out based on Henan pollution census update data ( 2010 ) . It is indicated that, all indicator of industrial pollution are high positive skewness distribution which are suited to catalogue sampling, the differentiation of industrial polluting sources into key sources and non-key sources is still feasible as an investigation principle in environmental statistics, complete survey is for key sources while sampling is for non-key sources. However, the cut-off point should be lowered down to 80%.
