摘　　要：以泉州湾滨海退化湿地为对象,通过野外调查、采样、实验室分析,初步研究红树林修复工程对土壤酶活性的影响。结果表明,退化湿地修复前土壤磷酸酶和脲酶活性分别为8.78~17.72μg/(g·24 h)和45.86~80.12μg/(g·24 h),修复后土壤磷酸酶和脲酶活性分别为10.21~14.22μg/(g·24 h)和85.83~102.22μg/(g·24 h)。在秋茄+桐花树+红海榄修复模式下,土壤磷酸酶和脲酶活性均明显增高;在秋茄+桐花树+白骨壤修复模式下,土壤磷酸酶活性明显降低,脲酶活性有一定增高;在秋茄+桐花树+木榄修复模式下,土壤磷酸酶和脲酶活性变化均不明显。This study focuses on analysing the effect of different combinations of mangrove plants on soil restoration using field investigation,sampling,and laboratory analysis methods.Quanzhou bay degraded coastal wetland are examined.Results show that the enzyme activity of phosphatase and urease before restoration at degraded wetland are in the range of 8.78~17.72μg/(g·24 h)and 45.86~80.12μg/(g·24 h),respectively,these numbers increase to 10.21~14.22μg/(g·24 h)and 85.83~102.22μg/(g·24 h)after restoration.Concretely on different plant combinations restoration,Kandelia obovata+Aegiceras corniculatum+Rhizophora stylosa result in the most substantial boost in soil enzyme activity.Kandelia obovata+Aegiceras corniculatum+Avicennia marina makes the phosphatase less active,while enhancing urease activity.Kandelia obovata+Aegiceras corniculatum+Bruguiera gymnorrhiza does not make a significant difference in enzyme activity.
