摘　　要：在按照近自然经营的原则及措施进行抚育管理和常规经营的千年桐生态林中分别选取3块样地,分析其土样理化性质.结果表明:经过近自然经营后的千年桐生态林土壤的含水量,氮磷钾、有机质含量均高于常规经营的千年桐林;土壤容重、比重和碳氮比则小于常规经营的千年桐林.由此可见,千年桐生态林的近自然经营可有效改善土壤理化状况,提高土壤肥力.Three plots of Aleurites montana eco-forests were selected by the rules and measures of intimate naturel management andnormal management, respectively, and the physiochemical properties of soil samples d each plot were analyzed. The results were asfollows ： water content, concentration of N, P, K and organic matter in the soil of.4. montana eco-forests by intimate natural manage-ment were significantly higher than those in the soil of A. montana eco-forests by normal management; the hulk density, specificweight, carbon nitrogen ratio in the plots dA. montana eco-forosts by intimate natural management were lower than those in the soilof A. montana eco-forests by normal management. It suggested that soil physiochemical properties and fertility were improved by inti-mate natural management.
