Research On Strategy Of Ecological Planningand Design Of Coastal Wetland Communities

Coastal wetland is an important living space and valuable resource and treasure,which human are relying on to live and develop. For a long time，lacking incognition of the protection of coastal wetland and excessive development and use, itlead to the serious loss and decrease of function and profits of coastal wetland, sowetland ecological system is in urgent need of restoration and protection. In recentyears, the coastal wetland communities as China’s regional development andutilization of coastal wetlands, its eco-build process lagged in comparison withexpansion and rapid development. This not only undermine coastal wetlandenvironment and resources, certain areas have also become constraints leadingfactor for socio-economic development of the region. This article sets the coastalwetlands communities as the study object, and explores of ecological planning anddesign strategies by establishing coastal wetland ecological planning and design oftheoretical models and methodologies, in order to achieve the ecological zoneconstruction of coastal wetlands and promote the rational utilization of wetlandresources and regional social, economic and environmental sustainability of coastalwetlands.Coastal wetland communities is located around a jagged strip of protectedareas with the outside world, with edge effects significantly, fragile ecosystems, andit is distinct from the general regional planning and design methods and models.This article uses empirical investigation, analysis and comparison, interdisciplinaryresearch and systems scientific methods, and follows the course of investigation,research and study on the practice of research work. First of all, this paper studiesthe features of coastal wetland eco-environment, analysis of access to coastalwetland communities on wetland eco-environment negative effects on the basis ofthe proposed coastal wetland communities existed in the planning and design of themany ills through field research and real-life case; and suggests it is urgency tosearch planning theory and methods which is suit for the characteristics of coastalwetlands. Secondly，Starting from the feature of coastal wetland ecologicalenvironment and the essence of ecological planning and design, the paper studiesthe conception of ecological planning and design of coastal wetland communities;Meanwhile defines objectives and evaluation criterion of the ecological planningand design. After researching principles relevant with ecological planning anddesign the of coastal wetland communities and model of cellular automata(AC)model, the paper constructs a CA theoretical model and puts forward a theoryframework for ecological planning and design of coastal wetland communities basing on CA model.From the view of methodology, this article bases on CA theory model ofecological planning and design in coastal wetland communities, and constructscoastal wetland zone of ecological planning and design methodology, of which thecore content includes geographical environment suitable for different communitiesof coastal wetlands utilization mode selection and adaptation communitiesecological planning and design of the ecological characteristics of coastal wetlands.And then, taking into account already established coastal wetland communitiesecological planning theory and method for design, the article put forward ecologicalstrategies for ecological planning and design of coastal wetland communities byadjusting the parameters in the model, which contains strategies of three aspects,natural wetland ecological conservation strategies, ecological design of artificialsystems of strategies and natural organic and artificial complex ecosystemOrganization strategies. Finally, combining with the methods of Systematic thinking,synergy in the organism, blend of different subjects and practice on ecologicalplanning and design of coastal wetland communities, here is an example ofconceptual planning of coastal wetland park in Liaohe delta. The design theory andmethod system constructed above are used in the example.It is applied to specificpractice on the aspect of strategies of ecological planning and design of coastalwetland communities through the conceptual planning and design of Liaohe deltawetland park. So it is realized to the organic combination between theory andpractice.In system thinking mode, this article integrates use of ecology, planning,architecture, landscape, as well as economics and other fields of knowledge throughinterdisciplinary study of coastal wetlands planning and design of ecological issues,reaches the following innovative results. The article constructed a coastal wetlandcommunity’s ecological planning CA theory model and system; established acoastal wetland communities ecological planning and design methodology;proposed strategies ecological planning and design for coastal wetland communities.The results of this research on planning and design of coastal wetland region aregoing to guide Chinese practice, and meanwhile also building an ecological studyon the planning and design of the basic framework and platform, with newperspectives and ideas, and trying to research on theories and methods of ecologicalplanning and design into the deeper, broader areas of active exploration.
