Study On Functional Zoning Of Wetland Park Based On Spatial Analysis

As an important way for rational utilization of wetland resources,wetland parks have been paid more and more attention from all walks of life.The functional zoning of wetland park not only plays a key role in guiding the planning and construction of wetland park,but also plays an important role in carrying out the zonal management work after the construction of wetland park.Although the function zoning of wetland park in our country has made the standard requirement on the partition content,it is still immature in the combination of the specific partition and the quantitative division of functional partition.Therefore,the study on functional zoning of wetland park has certain significance and value.This article summarizes the research and construction status of the functional zoning of wetland parks at home and abroad,and puts forward the status quo of zoning distribution irrational,improper combination relations,and difficult to achieve quantitative division.Through the analysis of the particularity of wetland parks,it is clear that the special features of its functional zoning are reflected in the diversity of its service subjects.Based on the analysis of relevant documents,concepts,and cases,it is pointed out that the functional zoning of wetland parks should meet the diversified activity demands put forward by the wetland ecosystem and the two major service providers.Based on the classification of requirements,a preliminary plan for the functional division model of wetland parks was proposed.In the process of improving the preliminary plan,we proposed scientific and data-acquired,quantifiable principles for the selection of zoning impact factors for wetland parks.Under the guidance of this principle,the functional impact factor system of wetland parks was explored and constructed in terms of wetland ecological quality and wetland construction suitability.In terms of ecological quality of wetlands,including eight factors: water environmental quality of wetlands,water resources in wetlands,waterfowls in wetlands,waterfowls in wetlands,relative abundance of wetlands,vegetation and surface coverage in growing season,invasive alien species,and human disturbance.In terms of wetland construction suitability,including twofactors: land use types and water distances.On this basis,a spatially-analyzed wetland park function partition model optimization scheme is proposed: Firstly,divide the wetland conservation area and the wetland restoration area,if the sum of the area of the two areas is greater than 60% of the total area of the park,continue to divide the service management area.among them,wetland conservation areas include two secondary divisions of wetland protection areas and wetland passive recovery areas.If it is less than 60%,the wetland restoration area will be reclassified into two secondary functional division of wetland active restoration area and wetland construction area and then divided into service management areas.Based on the above study,this article aims at the specific conditions of the first phase of the Changziying Wetland Park,obtained spatial data collection of impact factors through field surveys,manual interpretation of remote sensing images,etc.After single-factor buffer analysis,multi-factor overlay analysis and other processes,according to spatial analysis,the optimized partition scheme of wetland parks and the specific division of functional zoning,combined spatial analysis results,reclassified the functional division of the first phase of the Changziying Wetland Park.The feasibility of the functional zoning of wetland parks based on spatial analysis was verified by comparison with the original functional zoning of the Changziying Wetland Park.
