Research On The Value Evaluation Of Wetland Recreation Environment Improvement

Wetland eco-tourism is one of the current research hotspots in tourism.As the largest wetland recreation site in the North China Plain,Bai Yang Dian integrates multiple functions.However,in recent years,problems such as excessive development and use of resources have caused serious pollution in the Bai Yang Dian tourism environment,which has had a devastating impact on the sustainable development of the scenic spot.One of the main reasons is the lack of a scientific and reasonable value evaluation of Bai Yang Dian wetland’s tourism resources.As a non-market tourism resource,Bai Yang Dian’s value is prone to be underestimated or the resources are invaluable.In particular,most Chinese scholars study the value evaluation of non-market tourism products or services in a static environment,ignoring the potential social and economic benefits and asset appreciation that may be brought about by environmental improvements,which makes the government and managers unable to take an objective perspective.Accurately recognize the development value of wetlands,it is difficult to compare the cost of environmental damage with the benefits of appropriate development of ecological protection,resulting in serious errors in the decision-making results,and brings serious consequences to the rational development,utilization and protection of environmental resources.Based on the above situation,by consulting a large number of domestic and foreign literature and research results on natural resource tourism value evaluation,based on comparative studies of various value evaluation methods,in view of the current situation of Bai Yang Dian wetland tourism resources and the need to improve the management of the scenic spot,choose to use the display The travel cost method that combines sexual preference and stated preference,and adds environmental improvement variables to the travel cost model,constructs a recreational demand model with improved environmental attributes,and calculates the economic value of improved environmental attributes based on this.Among them,the environmental attribute improvement elements focus on the four key environmental attributes of "increase water visibility","reduce the amount of garbage","enhance infrastructure functions",and "enhance biodiversity",and measure their respective price elasticities and consumer surplus.According to the analysis results,the following conclusions are drawn:First,with the continuous increase of the four environmental improvements,the elasticity of demand for recreational prices of tourists to the Bai Yang Dian Wetland has declined,indicating that tourists have a higher willingness to pay for environmental improvements.The environment has improved,and tourism income in scenic spots has increased.Second,the changes in consumer surplus under the four environmental improvement states are all positive,and with the enhancement of environmental improvement conditions,the amount of increase is also increasing.Overall,environmental improvement programs that increase water visibility and enhance biodiversity are better than reducing garbage and enhancing infrastructure functions.Third,the economic value of any scenic spot with improved environmental attributes exceeds the current environmental state,with the lowest being 2.5 times the current economic value and the highest being 8.5 times.This study assesses the recreational value of Bai Yang Dian tourism resources from the perspective of environmental improvement.It is a useful exploration to promote the dynamic value evaluation of Bai Yang Dian tourism resources.It has important theoretical and practical significance for the future environmental improvement management of Bai Yang Dian and the formulation of development strategies.
