摘 要：The present paper attempts to identify the spatial patterns of soil nutrients at a waste disposal site in Haizhou opencast coal mine using geostatistical approach.108 soil samples were collected and analyzed for pH,organic matter(OM),NHN,available phosphorus(AP)and available potassium(AK).The results indicate that nutrients exhibited different spatial distribution and only NHN exhibited strong spatial dependence and a relatively large nugget *** high content of OM,NHN,AP and AK was seen in the northeastern part,whereas pH was higher in central north and southern parts of the waste disposal *** identification of the spatial variability and heterogeneity of soil properties and especially nutrients in waste disposal sites allows the assessment of soil quality and revegetation potential while it defines the possible need for amendments and the most feasible revegetation scheme.
