摘　　要：对 35年生栓皮栎人工林及相邻荒山的土壤理化性质及酶活性进行了比较研究 .结果表明 ,荒山营造栓皮栎后 ,林地的孔隙状况得到明显改善 ,土壤结构稳定性增强 ,林地养分得到富集 ,土壤生物活性加强 .栓皮栎人工林具有较好改良林地肥力的功能 。The effect of Quercus Vqriabilis plantation upon the physical properties,chemical properties and enzyme activities of soil was contrasted with barren hill in the neighbourhood.The result shows that soil porosity was improved distinctly,structure stability,nutrition and organism activities were enhanced in the Quercus Vqriabilis plantation.Due to its function of soil fertility improvement,Quercus Vqriabilis is one of broadleaved tree species for popularization.
