| Abstract: | Understanding the spatial variability of water quality parameters in the lake and determining their adequate sampling amount is an important precondition to carry on the research of water environment.Taking Meiliang bayou,Taihu Lake as an example,the paper studied the spatial variability of five water quality parameters which included SS,COD,TN,TP and Chl-a by geostatistics.Given that,the method of determining adequate sampling amount for lake water quality parameters was put forward.The result shows that five water quality parameters are not uniform in the spatial distribution,their spatial heterogeneity degree is SS
