通过对细柄阿丁枫和杉木纯林根际土、全土及混交林全土的研究结果表明：两树种均具有明显根际效应，但细柄阿丁枫的根际效应比杉木的大；根际土有机质、全氮、土壤微生物组成和区系及土壤酶活性均比全土大，但速效性氮、磷、钾则比全土小；与杉木纯林相比，混交林土壤生物学活性得到一定程度的改善，混交林中杉木平均树高和胸径分别是杉木纯林的1.16倍和1．20倍，混交林林分总蓄积比杉木纯林增加19．99％． The results showed that both rhizosphere effects of rhizosphere soil, all-soil and mixed forest of Pinus sylvestris var. Soil organic matter, total nitrogen, soil microbial composition and fauna and soil enzyme activity were larger than the whole soil, but the available N, P and K were less than the whole soil; Compared with pure Chinese fir plantation, the mixed soil had a certain degree of biological activity , The average tree height and DBH of Chinese fir in mixed forest were 1.16 times and 1.20 times that of pure Chinese fir forest, respectively. The total volume of mixed forest increased 19.99% than that of pure Chinese fir plantation.
