Abstract

Abstract: Three problems of disposal and utilization of sludge are necessary to be solved by applying it in agriculture and forestry:①The possoblity of heavy metals in sludge causing second pollution to soil and crops.②The potential effect of pathogens on the environment.③Groundwater pollution caused by high Nand Pconcentration.The aiteratures on the above three problems home and abroad were summarized in this paper.

Key words: spatial heterogeneity, geostatistics, soil mineral component, small catchment, Karst.
