桉树人工林3种生态系统服务的权衡关系对营林模式的响应
Response of Trade-off Relationships among Three Ecosystem Services in Eucalyptus spp.Plantations to Silvicultural Models
摘要
Abstract
To explore the co-evolution of ecosystem services of Eucalyptus spp.plantations under different sil-vicultural models can provide a theoretical basis for the management of Eucalyptus spp.plantations.In this study,40 sample plots were set up according to two silvicultural models(traditional silvicultural and mechan-ical silvicultural)and four forest ages(1 a,2 a,3 a,4 a).The Soil Organic Carbon(SOC)regulation,Total Nitrogen(TN)regulation and species diversity of the selected stands were measured.The Root Mean Square Deviation(RMSD)and Generalized Linear Mixed Model(GLMM)were used to analyze the trade-off and synergy relationship of different ecosystem services and their influencing factors.The results showed that:(1)With the increase of forest age,the soil SOC content under the mechanical silvicultural model gradually decreased and tended to be stable.However the TN content decreased first and then increased,which was not significantly different from the traditional silvicultural model.The species diversity was low in the early stage of mechanical silvicultural,but the species diversity gradually recovered with the increase of forest age.(2)There was a clear trade-off relationship between soil SOC regulation,TN regulation and species diversity.A-mong them,species diversity in mechanical silvicultural model had a relatively high benefit.With the increase of forest age,the traditional silvicultural tends to soil SOC benefit,and the mechanical silvicultural tends to soil TN benefit.(3)The average diameter at breast height and stand age were the key factors affecting the trade-off relationship of ecosystem services.In summary,when implementing mechanized operation and man-agement,we should fully consider the spatial heterogeneity characteristics of ecosystem service trade-off rela-tionship and the differences in their driving mechanisms.Through precise localized artificial regulation meas-ures,the trade-off conflict between service functions can be effectively alleviated,and the synergy optimiza-tion of ecosystem service functions can be realized.关键词
