Studies On Comprehensive Evaluation Methods About Spatial Variation Of Seepage Contamination Concentration

Comprehensive evaluation on spatial variation of seepage contamination concentration will help to discover the distribution rule and trend of seepage contamination. On the basic of this, the layout of pollution control and environmental management will be more proper. But we can't get the comprehensive information of spatial variation only by the current traditional statistics 1 and geostatistic methods.In this study, traditional statistics, geostatistic, ArcGIS together with comprehensive evaluation method were combined. Comprehensive evaluation methods on spatial variation were worked out by the study of local sample data from Langfang city and inside simulate experiment data. Conclusions can be described as: (1) Models of comprehensive evaluation were constructed and spatial variations of the data were analyzed on four directions and on all direction. (2) We drew a comprehensive environmental quality map by Kriging and GIS. (3) We got synthetical date of contamination with spatial information from the map and evaluated comprehensive spatial variation of multivariable data.Through studying seepage contamination data of Langfang city, we got the comprehensive indexes of spatial variation of eight sorts of contamination, comprehensive spatial variation of multivariable data and the comprehensive environmental quality map. All the results will be valuable to utilizing of seepage water, optimizing of monitoring net and controlling of pollution of Langfang city.
