The Application Of Restorative Design In The Wetland Landscape Of Southeast Lake In Liaocheng

Wetland is hailed as "kidney of the earth", which is a unique ecosystem on the earth. In recent years, because of the pollution, wetland resources have been consumed unduly and a decrease of big area wetland has happened, so how to remit the degeneration of wetland and recover the wetland which is degrading or degraded yet has become the focus of experts and scholars at home and abroad. There are both ecological and landscape functions of urban wetland park. For the landscape design of wetland, how to combine it with wetland recovery effectively, and to make the sustainable development of wetland in healthy way has become the task needed to be solved urgently of wetland restorative design.Based on the theory of ecological restoration project, restoration ecology, ecological aesthetics, this paper proposed the landscape restorative design of Small and medium urban wetland park in thought and method. And it researched Liaocheng Southeast Lake Wetland as a case study, carries on the case study, the main research results are as follows:(1) Based on the theory of ecological restoration project, restoration ecology, ecological aesthetics, this paper proposed the landscape restorative design of small and medium urban wetland park in its goal, principles, system and explored thought and method of the design. The study concluded that landscape restorative design of small and medium urban wetland park mostly includes these four areas: water, substrate, plant and biodiversity.(2) Four ways of the landscape restorative design of small and medium urban wetland park were proposed, more details was as follows: Water revitalization design contains natural water circulation and water purification; Matrix restorative design includes soil purification and landform design; Plant restorative design should be integrated into the cultural landscape, plant disposition and seasonal change; Biodiversity restorative design mainly was biological community restorative design.(3) In the case of Liaocheng Southeast Lake Wetland, the method of design for small and medium-sized urban wetland landscape restorative design was explored.When it came to the general layout of restoration design, the local culture and requirements need to be integrated into design, on the principle of retention, perfection, moderation and feature, made reasonable division, organized the land and water transportation; built ancient city around with water. For the wetland landscape specialized restorative design, it needed to respect the existing eco-systems, focused on water, soil, plant and community of these four parts. For example revetment was ecological style, purifying contaminated soil to improve soil fertility, making graceful plant sight, construct corridor for animals to habitat, feeding and migration, and many other specialized design, in order to enrich and make concrete design of small and medium-sized urban wetland landscape restorative.There were diversity and complexity in small and medium cities' wetland parks so that it's difficult to the restorative design of Southeast Lake Wetland landscape. This paper aims at providing theoretical basis for the construction of Liaocheng Southeast Lake Wetland landscape, and providing reference for the building of other urban wetland park landscape through this subject research.
