Title: Spatial distribution of water quality parameters in Lake Kuncheng
Abstract:Spatial characteristics are very important for water quality assessment and environmental control of a lake. A total of 18 samples were collected in Lake Kuncheng, which has a total area of 17.57 km2....Spatial characteristics are very important for water quality assessment and environmental control of a lake. A total of 18 samples were collected in Lake Kuncheng, which has a total area of 17.57 km2. Spatial variation characteristics of the lake were studied using the geostatistical component of Arc GIS. The results document the spatial variability of the water quality parameters and the nugget effect of each parameter. Interpolation with ordinary kriging was applied to identify different levels of water pollution and then spatial structure figures were outlined. The figures show spatial heterogeneity of the main parameters. The DO concentration is higher in the west. The TN and NH+4-N concentrations are high mainly in the northeast and east. The spatial heterogeneity of TP is very complicated, with high concentrations mainly in the northeast and west. The Chla concentration is high over the whole lake except for a small area in the middle. These results should be instructive to the environmental management of Lake Kuncheng.Read More
