Study On The Construction And Space Structure Of Community Eco-network Based On Landscape Ecology Principle

The fast urbanization in our country has drastically in the need of community construction, and dissects many important ecological corridors, shrinks Lake Wetland, losses ecological diversity. Even though, community ecological planning has been paid widespread attention, we can't get rid of traditional thinking mode of "figure-ground" relation in our community planning and design, buildings are often refined finely as "figure", just then natural ecological landscape patch, such as Greenland is designed as "ground" as buildings collateral "filling stuff", so community natural ecosystem can't refined and screening finely. Constructing community eco-network is to change tradition ways of planning and design, using landscape ecology principle, natural ecosystem and landscape patch should be brought into community general planning design. We could use ecological corridor as a tie to link those relatively independent landscape patch into a continuous and integrated eco-network which is also viewed as the skeleton of community. Such the structure has the functions of natural ecological service, life-form variety protection, stroll about or rest of sight, and directing the development of community space into a rational way.The thesis contains five parts:Section one introduces the research background, points out three deficiencies on wholeness of ecosystem, regional characters of eco-elements and diversity of eco-composition, which are ubiquitous in community ecological planning, meanwhile, the development of community eco-network planning study of both internal and international communities are described, and the research frame is established.Section two introduces the theory and method, it specifies the definition of some relative concepts, discusses the connotation of community eco-network, takes some principles as the supports of the research by introducing landscape ecology, and meanwhile translates the pattern "patch, corridor, matrix" into "node, route, ace", which is fit for community ecosystem, then lays out the mechanism, "joint, choroid, structure" for the constructing community ecosystem.Section three is the core part of thesis, starting form community ecosystem character, this paper expounds three important eco-components constructing "virgin, symbiotic, regenerated" and put them into studying on the construction and space structure of community eco-network all though, bases on the analysis about problems of community ecological planning and components of community ecosystem. Then, based on conversion platform and research mechanism, this part studies on the construction of community eco-network "joint, choroid" from the "node, route" of landscape patch and corridor, studies on the space structure of community eco-network "structure" from the "face" of landscape matrix. At this time, it also classifies community eco-nodes into intersection nodes, attached nodes, unattached nodes; classifies eco-routes into water routes, plant routes; classifies eco-construction into core, axis and complexness, and then couples of ecosystem and community space.Section four takes the community ecological planning of Longxiang villa Huludao city as an example. This work introduces three aspects (i.e. node, route, face) to link ecosystem to community space, further leading to a rational community planning and development.Conclusions are in section five with constraints discussed, and a summery of directions for future work.
