This study taking Xigao Village in Shanxi Province as the study area,based on Soil-landscape model,GIS and geostatistics methods forecasted the soil nutrient condition after reclamation and then compared it with the former condition.The results showed that: the variation degree,the nugget factors and the ranges of soil nutrient conditions reduced and the nugget factors and variable range had moderate spatial correlation after reclamation.Moreover,the distribution of soil nutrients became more uniform and the difference in nutrient contents between villages and farmland reduced after reclamation.Based on these results,the study puts forward some suggestions on soil fertility.This study is of practical significance for soil management and fertilization in this area,and provides a reference to studies on spatial temporal features of soil nutrients in other reclaimed areas.%以位于山西省晋城市泽州县西郜村为研究区,基于土壤-景观模型,利用GIS与地统计学的方法预测了复垦后土壤养分状况,并将其与复垦前土壤养分状况进行对比分析.研究结果表明:复垦后,土壤有机质、全氮、速效钾、有效磷的变异程度、块金系数与变程均会降低,且块金系数与变程在复垦后均具有中等程度空间相关性;复垦后较复垦前土壤有机质、全氮、速效钾、有效磷分布更为均匀,村庄与农田土壤养分含量差异降低.基于上述研究结果以及研究区实际状况,提出了相应的土壤培肥建议,对今后研究区农田管理与施肥工作具有实际意义,并为其它区域复垦前后土壤养分变化研究提供参考.
