| 摘 要： | 在云南省大关县木杆镇选择4种筇竹林分类型：天然筇竹—阔叶树混交林、天然筇竹—山茶混交林、天然筇竹—人工黄皮树混交林、人工筇竹—黄皮树混交林等，研究不同筇竹林分类型、不同土层深度(0~20、20~40和40~60 cm)的土壤过氧化氢酶、蔗糖酶、酸性磷酸酶和脲酶活性。结果表明：1)天然筇竹—阔叶树混交林的土壤过氧化氢酶、酸性磷酸酶和脲酶活性高于其他3种林分类型，人工筇竹—黄皮树混交林的土壤蔗糖酶活性高于其他3种林分类型，说明人工施肥处理对提高蔗糖酶活性有一定的作用；2)除天然筇竹—阔叶树混交林的蔗糖酶外，4种林分类型的土壤酶活性在土层0~20 cm达到最大值，并且随着土壤土层深度的增加而降低；3)除天然筇竹—人工黄皮树混交林的蔗糖酶和脲酶与过氧化氢酶、人工筇竹—黄皮树混交林和天然筇竹—山茶混交林的酸性磷酸酶与过氧化氢酶、天然筇竹—阔叶树混交林的酸性磷酸酶与蔗糖酶无显著相关外，其他酶活性之间均存在显著或极显著相关(P＜0.05或P＜0.01)。研究表明林分类型和土层深度是影响土壤酶活性的重要因素。

| Abstract: | Four types of Qiongzhuea tumidinoda forest are selected in Mugan Town, Daguan County, Yunnan Province, including natural Q. tumidinoda-broadleaf tree mixed forest, natural Q. tumidinoda-Camellia reticulata mixed forest, natural Q. tumidinoda-artificial Phellodendri Chinensis mixed forest and artificial Q. tumidinoda -Ph. Chinensis mixed forest, to study the activities of soil catalase, invertase, acid phosphatase and urease in the different types of Q. tumidinoda forest and different soil depths (0-20, 20-40 and 40-60 cm). The results show that:1) The activities of soil catalase, acid phosphatase and urease in the natural Q. tumidinoda-broadleaf tree mixed forest are higher than those of the other three forest types, and the soil sucrase activities of artificial Q. tumidinoda-Ph. chinensis mixed forest are higher than those of the other three forest types, indicating that the artificial fertilization treatment has a certain effect on increasing the activity of sugarcane enzyme; 2) Except for the sucrase of natural Q. tumidinoda-broadleaf tree mixed forest, the soil enzyme activities of the four types of stands reach the maximum at 0-20 cm, and decrease with the increase of soil depth; 3) Except that there is no significant correlation between sucrase & urease and catalase in natural Q. tumidinoda-artificial Ph. chinensis mixed forest, between acid phosphatase and catalase in artificial Q. tumidinoda-P. chinensis mixed forest and natural Q. tumidinoda-C. reticulata mixed forest, and between acid phosphatase and sucrase in natural Q. tumidinoda-broadleaf tree mixed forest, there are significant or extremely significant correlations between other enzyme activities (P <0.05 or P <0.01). The results indicate that stand type and soil depth are important factors to affecting soil enzyme activity. |
