Research On Conservation And Landscape Planning Of Wetland Park Based On Landscape Ecology

With the rapid development of urbanization,urban wetland area continued to shrink,the function of the wetland ecosystem gradually degraded,urban ecological environment suffered severe damage,wetland park as an important part of urban green space,it is of great significance to protect the wetland and improving urban ecological system.Due to the lack of theory about of comprehensive systematic protection and planning,the planning and construction of many wetland parks in China that appear this phenomenon of seriously copy and plagiarism others,exceedingly exploit and utilize resources,and poor ecological benefits.Therefore,this paper using method of literature analysis,method of case analysis,synthetic method and induction,survey research and method of example verification,the protection and landscape planning of the wetland park from the Angle of landscape ecology were studied,the main results are as follows:First,through to analyse landscape structure of London wetland park,the Hong Kong wetland park and Harbin national urban wetland park,put forward landscape planning concept that plan the landscape from the whole,in order to maintain the landscape heterogeneity and diversity,give priority to stability of ecosystem,properly enhance regional cultural characteristics.Combine with other related disciplines at the same time,summarized when the wetland park for landscape planning should follow the principle to protect the integrity of the landscape structure and continuity of corridor,continuity between patch and patch,diversity of the plaque types,sustainable development of landscape structure,comprehensive coordination and reasonable planning.Second,study the landscape planning of wetland park using the"patch-corridor-matrix" model,which mainly includes two aspects:plan of spatial pattern and plan of spatial structure.To plan the landscape spatial pattern,according to the function of various ecological plaques of wetland park to arrangement space,the core of landscape space as a reserve,the periphery is zone of buffer and transition,the most outer layer is area for visit and activity;Synthetically consider factor that width of corridor,shape of corridor,distance between plaques and visitors flow rate to arrangement spatial sequence.When plan corridor of road should give priority to connect each function patch,disperse flow and reduce human disturbance,try to avoid dismembering plaques,reasonably set the tourist route and landscape view combine with distribution of landscape node at the same time.Plan the Landscape spatial structure of wetland park on the basis of functional partition of park,reserve and restore native wetland patches,plan artificial wetland patches on its periphery,properly arrangement active patches to meet human entertainment;Plan corridor of road for the principle that many number in activity area,little number in buffered area and nothing in reserve.Plan corridor of water in order to reduce water pollution and increase the contact between the aquatic plaque and the terrestrial plaque.Give priority to obstruct the interference from the external environment and protect the internal ecological plaque when plan corridor of forest.Third,through to verify example of the WuLongJiang wetland park,summarize principle and method that the functional partition,the traffic organization planning,the plant landscape planning,the plan of protection of the wetland park,provide guidance for other wetland park landscape planning,protect wetland and promote the sustainable development of wetland park together.
