Baiyangdian Wetland Ecosystem Service Value Evaluation Research

With the advancement of the reform of the ecological civilization system,the idea that green water and green mountains are golden mountains and silver mountains has become more and more popular.Exploring the identification,measurement and information disclosure methods of the value of ecological assets is an important measure to practice the"two mountains" theory and also to build an environment-An important basis for the economic integration accounting system.The "Decision of the Central Committee of the Communist Party of China on Several Major Issues of Comprehensively Deepening Reform" proposed for the first time the exploration of the preparation of natural resources balance sheets.Subsequently,the "Pilot Program for Preparation of Natural Resources Balance Sheets" and the "13th Five-Year Plan for National Ecological Protection" were proposed separately Carry out pilot work for preparing natural resource balance sheets and ecological resource asset evaluation.Since the start of the pilot work,exploring the conversion between the physical quantity and value of ecological resource assets,exploring scientific accounting and measuring the balance of various natural resource asset statements,has become a difficulty in the preparation process of the statement,and has also become a decision on the natural resource balance sheet statement.The technical key to the quality of information disclosure.Baiyangdian Wetland is located in the core area of Beijing,Tianjin,and Hebei.It is the largest freshwater wetland in the entire North China Plain.The value of ecological services provided by it is of great significance to the promotion of local economic development.The preparation of the Baiyangdian Wetland's natural resource balance sheet is useful for improving the area.The internal ecological civilization performance evaluation and accountability system is very necessary.However,the existing research cannot provide a reasonable conversion between the physical quantity and value of Baiyangdian Wetland ecological resource assets,cannot realize the confirmation and measurement of the fair value of Baiyangdian Wetland ecological system services,and cannot provide relevant data in the Baiyangdian Wetland natural resource balance sheet.The report provides reference,which makes managers lack basis when carrying out value management work.Based on the above background,this article has carried out the following research:First,through combing the literature on natural resource asset element accounting,ecological asset evaluation methods,ecosystem service value evaluation,etc.,it is found that the ecosystem service value evaluation is the item accounting of natural resource ecological service value and ecological profit and loss in the natural resource balance sheet It provides a theoretical reference,but the evaluation of ecosystem service value in China is still in the development stage.The final ecosystem service and service value classification standards have not been determined,the evaluation methods and evaluation indicators are not standardized,and the conversion between the physical quantity and value of ecological resource assets,Lack of research in management application;Secondly,according to the overview of Baiyangdian Wetland,combined with existing research results,the final services of the ecosystem include product supply,water resources supply,leisure tourism,cultural education,flood regulation and storage,Regulate climate,fix carbon and release oxygen,purify water quality,and use this as the choice of three types of evaluation methods of ecological asset value evaluation:direct market method,alternative market method and creation market method,and build the basis for the service value evaluation index system;Thirdly,this article is based on the "Hebei Rural Statistical Yearbook","Baoding Economic Statistical Yearbook" and field survey data to analyze the various aspects of the Baiyangdian Wetland Ecosystem Evaluation of the service value shows that the ecosystem service value of Baiyangdian wetland is 321.86×108 yuan,of which the use value is 207.32×108 yuan(the direct use value is 43.74×108 yuan;the indirect use value is 163.58×108 yuan),accounting for the total 64.41%of the value;the non-use value is 114.54×108 yuan,accounting for 35.59%of the total value;Finally,according to the value evaluation results,the natural resource assets in the Baiyangdian Wetland will be audited,accountable for ecological damage,and regional industrial layout planning and determination.Suggestions for application of ecological compensation for"lost land" and "lost lake" residents.This article evaluates the value of ecosystem services from the perspective of natural resource balance sheet compilation.It is a useful exploration for advancing the preparation of natural resource balance sheet,and it is also a further attempt to promote the management of ecological asset value.
