A Typical Wetland Park Around The Dianchi Lake Ecological Zone Assessment Of Ecosystem Services And Visitor Perception

As the first of the nine plateau lakes in Yunnan,the importance of Dianchi Lake is obvious.The management of Dianchi has a crucial role in Yunnan’s development,and the lakeside ecological zone around Dianchi,as the last barrier to intercept pollution from Dianchi,has become the core ecological landscape while undertaking environmental purification functions.The management of the lakeside ecological zone around Dianchi and the construction of wetland parks on it have lasted for many years and have achieved certain results,but there are fewer studies on the changes brought about before and after the construction,and there is a lack of quantitative scientific evaluation.Based on this,This thesis takes the lakeside ecological zone around Dianchi at the macro level and three typical wetland parks(Laoyuhe National Wetland Park,Nandianchi National Wetland Park and Baofeng Peninsula Wetland Park)at the micro level as the study area.Analyses the evolution of their landscape patterns before and after construction using field research,landscape pattern index and landscape map theory methods.The value calculation system is based on the ecosystem service assessment system,and the equivalent factor method is used to calculate the corresponding value;the network text analysis method and questionnaire survey method are used to assess the perceptions of visitors,and the problems of the current construction of typical wetland parks are summarised based on the research results and the corresponding solutions are proposed;finally,an attempt is made to optimise and improve the landscape of the three typical wetland parks.The thesis provides a design method that combines landscape pattern,ecosystem services and visitor perception as design objectives,with a view to providing a reasonable assessment system for the ecosystem services and visitor perception of other wetland parks in the lakeside ecological zone around Dianchi and even the same highland lake-type wetland parks,and laying a theoretical foundation for the rational planning and construction of the corresponding landscape creation and park management.
