However, we can find the rules such as the pipe model, the elasticity model and so on. We try to integrate them under the concept of the metabolic ecology. ABCDABC写真、図Long term monitoring site in natural oak forest in Hokkaido. Research on damaged tree. 写真、図Long term monitoring site in Kiso to examine the regeneration process of Hinokicypress.Vegetation Structure and Dynamics: Different plant species and its population is a unit of the vegetation. The competitive and cooperative interactions among resource and environment will result their relationships.Silviculture and Forest Management: The objects of silviculture has been changed in the history. We try to act the conservation biodiversity in artificial forest with low cost. We also try to success the recruitment of trees in disturbed or sasa-covered land.Division of Forest and EnvironmentalSymbiosis SciencesLaboratory of SilvicultureTetsuohSHIROTAAssistantProfessorTreearchitecture,Lifehistoryofwoodyplants,Populationecology,Biodiversity,NaturalregenerationTogettheforestecosystemservicessustainablyinthechangingworld,theecologicalandreasonableforestmanagementisrequired.Torealizeourobject,wetrytounderstandthebehaviorofwoodyplants,thedynamicsofforestecosystemsandtheirresponsetothehumanactivity.Becauseforestecosystemsreactsluggishlytonaturaldisturbancesandhumanimpacts,andtheirresponsesaredifferentdependingonfieldcharacteristics,weadoptthreestrategyinourlaboratory:(1)longtermecosystemmonitoring,(2)accumulationandanalysisthepracticalfielddata,(3)comparisonthefielddatawiththetheoreticalmodels.LifeHistoryanditsstrategyofWoodyPlants:Woodyplantsrepresentvariousshapeandsize.However,wecanfindtherulessuchasthepipemodel,theelasticitymodelandsoon.Wetrytointegratethemundertheconceptofthemetabolicecology.ABCDABCWe have monitored the vegetation structure in the thinned Japanese cypress forest for 20 years.Vertical transition pattern of vegetation from cool temperature zone to one of subalpine zone response to the global warming.VegetationStructureandDynamics:Differentplantspeciesanditspopulationisaunitofthevegetation.Thecompetitiveandcooperativeinteractionsamongresourceandenvironmentwillresulttheirrelationships.SilvicultureandForestManagement:Theobjectsofsilviculturehasbeenchangedinthehistory.Wetrytoacttheconservationbiodiversityinartificialforestwithlowcost.Wealsotrytosuccesstherecruitmentoftreesindisturbedorsasa-coveredland.Division of Forest and EnvironmentalSymbiosis Sciences31
