摘　　要：根据山西省11个生态类型区筛选样地,评价油松土壤养分概况;采用"累积法"计算森林生产力,探寻其与土壤养分的相关关系。研究结果表明,油松人工林土壤有机质、全氮、全磷、全钾水平分别为缺乏、中等、缺乏、中等,速效磷和碱解氮水平为中等、缺乏;土壤有机质、全氮、全磷、全钾和碱解氮与林分生产力的关系呈显著或极显著水平,土壤全钾、速效磷与林分生产力关系不显著。Pinus tabuliformis forest soil quality condition in Shanxi Province and the relationship with forest productivity were studied.According to the 11 ecological regions in Shanxi Province,sample plots were selected to evaluate the Pinus tabulaeformis soil quality;Accumulation method was used to calculate the forest productivity and explore its correlation with soil nutrient.TOC,TN,TP,TK were lack,medium,lack,medium;AP,AN were medium,lack;The relationship between soil organic matter,total nitrogen,total phosphorus,total potassium and alkali-hydrolysis nitrogen and forest productivity was significant or extremely significant;there was no significant relationship between total potassium and available phosphorus in soil and forest productivity.
