摘　　要：为探究杉木林下产业的发展对土壤质量的影响情况,对林下土壤酶活性进行了测定。结果表明:同一林下经济模式下不同土层的土壤酶活性随着土层的增加呈现先上升再下降的趋势,在10~20 cm处数值最高;不同模式下同一土层的土壤酶活性呈现出林禽模式强于纯林,除脲酶活性外,林禽模式土壤酶活性均强于人为干扰林模式。研究结论可为粤北杉木林下经济模式的探索提供一定的参考。In order to explore the influence of the development of under-forest industry of Cunninghamia lanceolata on soil quality,enzyme activities in the understory soil were measured.The results showed that the soil enzyme activity in different soil layers under the same under-forest economic model showed the trend of increasing first and then decreasing with the increase of soil layer,and the value was the highest at 10~20 cm.Under different models,the soil enzyme activity in the same soil layer showed that the Tree-Poultry model was stronger than the pure forest,and the soil enzyme activity in the Tree-Poultry model was stronger than that in the artificial disturbance forest model except urease activity.The research conclusion can provide a certain reference for exploring the economic model of Cunninghamia lanceolata in northern of Guangdong.
