以中亚热带地区不同演替阶段次生林为对象,研究了马尾松+石栎针阔混交林(PM)、 南酸枣落叶阔叶林(CA)及青冈+石栎常绿阔叶林(CG)2种调节服务[土壤有机碳(SOC)调节、 全氮(TN)调节]及1种支持服务(物种多样性)之间的权衡与协同关系及其影响因素.结果表明:CA的物种多样性显著高于PM、CG,CA与CG的土壤SOC、TN含量显著高于PM.3种次生林土壤SOC调节与TN调节为协同关系,物种多样性与土壤SOC、TN调节为权衡关系,PM、CA权衡表现为物种多样性具有相对较高的收益,CG权衡无固定的相对受益方.在演替前期,常绿阔叶树种比例、 土壤pH分别与土壤TN调节-物种多样性、 土壤SOC调节-土壤TN调节的权衡呈负相关,随着演...

Three ecosystem services (S_E),including,soil organic carbon (SOC) concentration,total N (TN) concentration,and plant species diversity,were analyzed in the following three subtropical secondary forests:Pinus massoniana +Lithocarpus glaber mixed forest (PM),Choerospondias axillaris deciduous broadleaved forest (CA),and Cyclobalanopsis glauca+L.glaber evergreen broadleaved forest (CG).The trade-off and synergy between the S_E and thecontributing factors of trade-offs were also analyzed.The results showed the following.(1) Plant species diversity...
