Research On Planning And Design Of Urban Wetland Park Based On Land Suitability Evaluation

Wetland park is the main carrier connecting people and natural wetlands.Its construction has become an important means to effectively protect wetlands.However,in the process of wetland development and construction,there is a lack of scientific and systematic methods,and blind development and utilization will break the balance of wetland ecological environment.How to scientifically and rationally utilize and plan the wetland park according to the uniqueness of the wetland,and develop and utilize the natural wetland and cultural and social resources under the premise of protecting them,so as to realize the sustainable development of the wetland has become the focus of the planning and design of the wetland park.In this paper,taking Liushaoyan Wetland Park as an example,10 land suitability evaluation factors were selected from the natural ecology and social economy,and the land availability evaluation factors of Liushaoyan Wetland Park were constructed by the relevant theory of analytic hierarchy process and the evaluation statistics data of expert scoring method,and then the proportion of the factors was determined one by one.Using the geographical analysis technology,the spatial image analysis was carried out on the evaluation factors obtained in the early stage,and each evaluation data was superimposed according to the corresponding proportion to determine the evaluation results of the land suitability of Liushaoyan Wetland Park.According to the final results and the classic cases of urban wetland park planning and design at home and abroad,the Liu Shaoyan Wetland Park should be constructed and utilized more scientifically and rationally.Through land suitability evaluation,the park is divided into four parts: suitable area,moderately suitable area,moderately unsuitable area,and unsuitable area,accounting for42.39%,33.45%,13.73%,and 10.44% of the total park area respectively.The planning and designing according to the evaluation results:Suitable areas with superior geographical conditions,convenient transportation,and weak ecological sensitivity in the park,mainly distributed in the periphery of the wetland park.This area has a large flow of people.During planning and design,it is used as a land for management services,publicity and display,and leisure activities to provide tourists with guide,catering,entertainment,and rest facilities.Moderately suitable areas with low ecological sensitivity,and appropriate artificial construction can be carried out.Therefore,in the planning and design,the suitable area is used as the dynamic area in the wetland park.On the basis of protecting the ecological environment of the wetland park,the interaction between the park and tourists is enhanced,and the site is mainly provided for tourists to watch and experience.The moderately unsuitable area is the transition zone of the unsuitable area,with a relatively complete ecosystem,rich and diverse biological species,strong ecological sensitivity,and a good natural landscape.As a quiet zone of the wetland park,this area is mainly used for protection and restoration to control the number of visitors and reduce the interference of visitors to the environment.It is mainly used for protection,viewing,exhibition,and popular science.Unsuitable areas have rich biodiversity,strong ecological sensitivity,and easy to be disturbed by tourists.They are mainly distributed in areas close to waters.Carry out key protection for this area,build necessary artificial passages for maintenance and management,and restrict visitors from entering.
