基于复杂网络分析法的层级生态网络结构研究 Abstract: Thehierarchicalecologicalnetworkstructurehasbeenwidelystudiedinrecentyears.Thecomplexnetworkanalysismethodisoneofthemostcommonlyusedmethodsforstudyingthehierarchicalecologicalnetworkstructure.Withthehelpofthisapproach,researcherscanexplorethehierarchicalstructureofecologicalnetworksmorecomprehensively,whichhassignificanttheoreticalandpracticalsignificanceforecologicalresearch.Inthispaper,wereviewedthecurrentresearchprogressofhierarchicalecologicalnetworkstructurebasedoncomplexnetworkanalysismethods,anddiscussedthechallengesandfutureresearchdirectionsinthisfield. Introduction: Ecologicalnetworksarecomposedofdifferentinteractingcomponents,suchasspecies,foodweb,habitats,andnaturalresources.Thesecomponentsareconnectedbydifferenttypesofinteractions,suchaspredation,competition,mutualism,andparasitism.Inrecentyears,thehierarchicalstructureofecologicalnetworkshasreceivedincreasingattentionfromecologistsduetoitscrucialrolesinecosystemstability,resilience,andbiodiversity.Thehierarchicalstructureofecologicalnetworksreferstothenestedandmodularpatternsofinteractionsamongthesecomponents,whicharecharacterizedbydifferentlevelsoforganization,fromtheindividualtotheecosystemlevel.Thehierarchicalstructureofecologicalnetworksisnotonlyafundamentalconceptinecologybutalsoanimportanttoolinecosystemmanagementandconservation.
