摘　　要：研究甘肃省临夏州太子山林区云杉幼林—油松林和云杉成熟林—杨桦林土壤化学性质与其土壤酶活性的相关性,为分析该地区不同林下土壤供肥能力、营养元素之间的动态平衡状况、维护地力、提高森林生产力等,提供有关土壤生物化学活性方面的科学依据。The correlation of soil chemical properties and soil enzymatic activity under young spruce forest-Chinese pine forest and mature spruce forest- poplar-brich forest in Taizishang forest farms of Linxia, Gansu Province were described. It provided scientific basis on biochemical activity for analyzing the soil fertility and nutrient dynamics in different types of forests, maintaining and improving soil productivity.
