摘　　要：通过对杉木拟赤杨混交林及杉木纯林土壤团聚体结构、土壤养分状况及酶活性的研究表明，与杉木纯林相比，混交林土壤结构性能得到改善，供肥和保肥能力加强，各种土壤酶活性提高，土壤肥力较好。表明杉木拟赤杨混交林具有良好的培肥土壤功能，对杉木人工林的地力维持和提高有重要意义。Through a study on soil aggregate composition, nutrient status and enzymatic activity under mixed forest of Chinese fir - Alniphyllum fortunei and pure stand of Chinese fir, the results indicated that, compared to pure stand, the soil structural property was ameliorated, the soil capacity of nutrient supplying and was improved, and the soil enzymatic activity were enhanced. It is concluded that the mixed stand can be able to be self-rich in soil fertility, which benefit the maintenance and improvement of site fertility under Chinese fir plantation.
