The service function of ecosystems is precious human intangible assets and wealth.Over the past century,various types of natural land,such as forests and wetlands,have rapidly decreased due to the unlimited use of ecological resources and the destruction of ecosystems.In a short period of time,people obtained a certain amount of income,but the service function of the ecosystem gradually decreased.People have been blindly changing the ecological environment and plundering ecological resources.This is particularly evident in the Poyang Lake ecosystem: Over-fishing on farmland around the lake has caused serious damage to the Poyang Lake ecosystem.This has led to a series of ecological crises,such as soil erosion,damage to biodiversity and depletion of resources.The impact of these ecological crises has gradually deepened into our daily lives.Therefore,this article uses intuitive economic data to reveal the great value provided by the Poyang Lake Wetland Ecosystem.It not only hopes to raise people's awareness of the importance of wetland ecosystem protection,but also makes rational use of ecological resources and ecology for government agencies and enterprises.The building provides the foundation.Therefore,this paper mainly studies the service functions of the Poyang Lake Wetland Ecosystem,evaluates the value of Poyang Lake Wetland Ecosystem Service Function through various suitable evaluation methods of ecological service functions,and concludes that Poyang Lake Wetland Ecosystem Service Function Status and Selection The reference objects were compared and specific suggestions were made to provide a theoretical basis for the construction and protection of Poyang Lake wetland ecosystem.The first chapter of this article is an introduction.The main contents include the research background and research significance,research contents and research methods,as well as the contributions and deficiencies of the research.The second chapter describes Poyang Lake wetland and its watershed profile through analysis and understanding of actual conditions and actual data.The basic generalization of Poyang Lake provides practical basis and research background for subsequent analysis.The third chapter mainly introduces the research methods of this article,and expounds the theoretical basis of this article.It mainly includes various ecological value assessment methods and current wetland ecosystem services.The current status of functional research classifies the value of service functions of wetland ecosystems,and analyzes the corresponding evaluation methods,and establishes a corresponding evaluation index system,which provides a theoretical basis for the following analysis;Chapter IV describes the Poyang Lake wetland ecosystem service function.Investigate and classify the function types,apply various corresponding evaluation methods to calculate,obtain the corresponding results,and compare and analyze the selected reference objects of the coastal wetland in Jiangsu;the fifth part combines the research of this article and carries out relevant recommendations.Summary and presentation.The main research conclusions and policy recommendations of this paper are drawn.According to the calculation results and reference objects,the direction of lake wetland ecological protection and construction was proposed.
