Study On The Suitability Evaluation And Planning Of Wetland Park Based On GIS Technology

As one of the three ecosystems,wetland has a variety of ecological functions.How to develop and protect wetland scientifically has become an urgent problem.Wetland park is a kind of park form which takes wetland as a carrier and further blends ecology,landscape and art.It can better play the function of wetland,improve the structure of wetland ecosystem,and play a protective role in the use of wetland.At present,the blind development and utilization break the balance of wetland ecological environment,the unsystematic planning method and the imperfect detection and management means after the development,which lead to a series of problems after the planning of Wetland Park.Therefore,how to carry out scientific and reasonable planning and construction to achieve the sustainable use of wetland park resources is a very realistic and significant topic.In this study,zhouyingshahe Wetland Park in Zaozhuang City is taken as the research area.Through the research and analysis of the theory and method of ecological suitability evaluation and the characteristics of GIS technology,the suitability evaluation system of zhouyingshahe Wetland Park in Zaozhuang City is constructed,and its suitability is evaluated and analyzed,as the basis of wetland park planning and construction,detailed planning and research are carried out.The results show that:1.Establish information database of zhouying shahe wetland parkUsing GIS technology,the factors of wetland park were classified into 7 categories: road,grassland,woodland,construction land,village,farmland and water area.By extracting all the factors in the research area,conducting classification and data statistics,the green space information database of zhouying shahe wetland park was established.2.Ecological suitability evaluation of zhouying shahe wetland park in zaozhuang city(1)establishment of ecological suitability evaluation index systemAccording to the ecological suitability assessment factor selection principle and method to determine the slope direction,slope,elevation,vegetation coverage,waters buffer distance,land use present situation,the distance from the road,or near the line distance,the distance from eight evaluation factors of residential area,constructs the zaozhuang Zhou Ying shahe wetland park ecological suitability analysis and evaluation system.According to the suitability classificationstandard,the single factor index is reclassified by using GIS technology.Analytic hierarchy process(ahp)is used to determine the weight after the overlay,get Zhou Ying shahe wetland park comprehensive ecological suitability analysis,the Zhou Ying sha river wetland park is divided into three level is not suitable,more suitable and suitable,respectively 15.22%,51.67% and33.11% of the total area,for the next step of zaozhuang Zhou Ying shahe ecological wetland park planning to provide scientific and reasonable reference basis.3.Study on the planning of shahe wet land park in zhouying,zaozhuang cityIn zaozhuang Zhou Ying shahe wetland park ecological suitability evaluation results as the foundation,according to the zaozhuang Zhou Ying shahe wetland park planning and guiding ideology,orientation and principles of wetland park planning,combining with the development of the wetland park protection requirements,the wetland park planning area,two rings,five district,"area" as the main part,"link" as the main a traffic circle,the "five zones" five functional partition,namely ecological conservation,restoration and reconstruction,respectively,show the mission area,reasonable use area and management service,on this basis,from the wetland park road traffic,water,drainage,revetment ecology and the ecological planning of vegetation.
