| 摘 要： | 研究了刺槐、臭椿纯林及其混交林中不同土层在不同季节土壤酶活性的变化。结果表明:各林分间的土壤酶活性在各个季节和土层均表现出差异。经统计分析,土壤酶活性在土层中的分布有一定的规律性,总的来说,随着土层逐渐加深,土壤酶活性逐渐减弱。在树木生长表现和土壤酶活性发挥方面,混交林优于纯林。

| Abstract: | The soil enzyme activities of different soil layers at different seasons in pure and mixed stands of Robinia pseudoacacia and Ailanthus altissima were studied. The results indicated that there were differences among different stands on soil enzyme activities at different season and soil layers, it's also shown that the distributions of the soil enzyme activities in different soil layers had some regularity, totally, the soil enzyme activities decreased gradually with the soil layer depth decreasing. Also, the tree growth and the soil enzyme activity of mixed stand were all better than that of the pure stands. |
