不同林龄天山云杉人工林土壤多功能性特征及影响因素
Soil multifunctionality and its influences across various ages of Picea schrenkiana plantation
摘要
Abstract
Soil multifunctionality is a vital component of ecosystem multifunctionality.Exploring the multifunc-tionality of soil in the Picea schrenkiana plantation at various ages offers valuable insights into soil capabilities.This research should enhance our understanding and support the management of vibrant forest ecosystems,mak-ing a significant contribution to environmental science.This study investigated the Picea schrenkianaplantation at the ages of 30,40,50,and 60 years,focusing on 15 indicators related to soil carbon,nitrogen,and phosphorus,to evaluate the soil multifunctionality of the Picea schrenkiana plantation.The findings reveal the following:(1)Soil moisture content,total nitrogen,and available nitrogen initially decreased before increasing with forest age,while daily average temperature and organic matter content exhibited a consistent decline with increasing forest age.(2)The activity of soil urease displayed an inverted"N"shaped trend concerning forest age,whereas the activities of cellulase and invertase initially rose and then declined.Catalase activity gradually decreased with in-creasing forest age.(3)Soil multifunctionality increased and then decreased with aging of the forest.The main factors affecting soil multifunctionality included the available nitrogen and urease.Therefore,forest age is a sig-nificant ecological factor that influences soil multifunctionality of the Picea schrenkiana plantation.In addition,managing related factors such as soil physical and chemical properties and enzyme activity is crucial.These re-search findings are significant for the sustainable management of Picea schrenkiana plantation on the northern slopes of Tianshan Mountains in Xinjiang.关键词
