Study On Restoration Strategy Of HZ Wetland Park Based On Ecological Concept

Ecological restoration is one of the important means to protect wetland ecosystem.HZ wetland is a composite wetland composed of rivers,reservoirs and stacking fruit forests.Ecological restoration can enhance biodiversity,improve environmental quality and achieve sustainable development goals.Based on the analysis of HZ wetland construction status,biological factors and environmental factors,the main problems were found as follows: serious landscaping traces of wetland construction,indistinct wetland ecological function,single biological community,unreasonable structure,indistinct wetland characteristics in wetland ecological conservation area,and water quality environment to be improved.Several specific ecological restoration schemes were designed for HZ wetland public open area,restricted open area and ecological conservation area by hydrological and water environment restoration method,wetland basement structure restoration method,vegetation restoration method and habitat construction method,including ecological silt clearance,berry plant planting,high tide habitat and beach.Tu area construction,ecological floating island,100 orchards and the establishment of scientific research monitoring system.In order to set the optimal ecological restoration strategy,the value engineering theory is introduced.Based on the analytic hierarchy process,three sets of ecological restoration strategy schemes are compared,and the most suitable ecological restoration strategy scheme is obtained.In addition,the brainstorming method is used to optimize the ecological restoration strategy scheme.Finally,the paper analyses the mutual adaptability of wetland related interest groups and evaluates the benefits of wetland ecological restoration based on the relevant historical account data of wetland managers and the data of surrounding similar areas.The calculation shows that the economic benefits are to increase the income of the park by 8.43 million yuan per year,reduce the cost of wetland conservation by 2.745 million yuan per year,and promote the surrounding areas.More than 20 headquarters of high-tech Internet enterprises have settled down;the ecological benefits are expected to add 61 species of forest birds and 13 species of waterfowl,and increase the capacity of 450,000 m3 storm water storage space;the social benefits are innovation and entrepreneurship,providing ecological restoration demonstration role for about 800 National Wetland parks,and promoting scientific research projects of more than 20 research universities in surrounding areas.Work.The study of ecological restoration strategy proposed in this paper not only promotes the sustainable development of HZ wetland,but also provides reference value for other wetland parks to choose reasonable ecological restoration measures in ecological restoration,which is scientific,practical and extensible.
