Study On Spatial Process Of Urban Wetland Ecosystem Services

Because of the unique water landscape staggered, rich natural resources andmany types of oecosystem service, the urban wetland has always enjoyed thereputation of being "kidney of the city"、"natural species pool"、"garden city" andmany other names.With the rapid development of urbanurbanization, urban wetlanditself and its wetland ecosystem service was on the comedown phase rapidly，manyenvironment problems aroused.Urban wedland was widespread concern andreceived imany attention. But due to the differences of wetland ecosystem servicesin form and dimension, in the practical of application, evaluation of the wetlandresources of various types of ecosystem service value analysis becomes a problem.In view of problem of urban wetland ecosystem services, Many researchers haveconducted a great deal of research and practice on it in recent years,has madesignificant achievements in theory, method and practice, but how to make anobjective understand the path of wetland ecosystem service transfering andrealization is a unsolved problem.Urban wetland is the unity the factors of the natural system and socialeconomic system of mutual influence, interaction. Research on ecosystem servicebelongs to the urbanof wetland ecosystem services category, in order to highlight thedistinctions and natural ecosystem services of energy flow, Embody the organicunity of ecological, economic and social value of urbanwetland, as clue to theenergy can reflect the essence of urbanwetland ecosystem services.economic andsocial value of urbanwetland, with energyas the clue, the energy value theoryevaluation can reflect the essence of urbanwetland ecosystem services. Therefore, inthis study, on the basis of emergy evaluation of Quanzhou Bay ecosystem servicesas the main line, combined with thestructure of urbanwetland ecosystem,constructing the corresponding model through the genera principleslof emergyanalysis. The realization of the process through urbanwetland ecosystem servicesassociated with the energy, to make a clear to all kinds of ecological economic flow transfer, transformation and interaction,between the urbanwetland ecosystemservices and regional social economic system, finally concluded the spatial transferrules of urbanwetland ecosystem services.
