| In recent years,with the development and utilization of water resources,problems such as water pollution and deterioration of water environment have become an important factor that constraining China’s economic and social development.The ecological environment of the river basin affects all aspects of people’s production and life.The quantification of ecological compensation in river basin has practical significance for water environmental protection and ecological protection.This paper relies on the National Natural Science Foundation of China’s "Study on Ecological Compensation in basin Water Environment Based on Ecological Economics and Control of Total Amount of Pollutant" to carry out a systematic study on the quantification of the bidirectional ecological compensation in river basins.The example of Xiaohong River Basin of Zhumadian is discussed,and the method of quantifying the bidirectional ecological compensation in the river basin is discussed.The main research contents and achievements are as follows:(1)Analysis of the Mechanism of Bidirectional Ecological Compensation in River Basin.From the perspective of safeguarding the upstream and downstream common interests of the river basin,considering the loss of value of downstream water bodies and the input of upstream pollution control,the relationship between loss of pollution value,treatment costs of pollutants and ecological compensation was analyzed.And the bidirectional ecological compensation of river basins was clarified.The connotation and mechanism provide the theoretical basis for the quantitative study of the bidirectional ecological compensation in the basin.(2)Construction of a quantitative model for ecological damage in river basins.Using the energy-analysis theory,the energy flow and energy-value conversion process of the water eco-economic system is analyzed,and the economic,social,and ecological environmental value accounting methods for water resources are given,the ecological economic value of water resources is calculated,and the pollutants are analyzed.The concentration loss is a function of the value of water loss,and a pollution loss rate measurement model is constructed.Based on the calculated water ecological economic value and pollution loss rate measurement model,combined with the basin water resources,an upstream-downstream basin ecological damage quantification is constructed.(3)Construction of a quantitative model for river basin ecological protection compensation.According to the monitoring data of the sewage treatment plant,the standard limits and operating costs of each pollutant were determined,and the treatment facility efficiency and pollutant treatment cost of pollutants were calculated;the ratio of the treatment cost to the concentration difference of the pollutants in the sewage treatment plant was calculated.Analyzes and constructs a governance cost model for single-contaminant-contaminated unit-concentration pollutants.Combined with the amount of pollutants processed,a quantitative model for upstream ecological protection compensation is constructed.(4)Example analysis.Based on the above-mentioned quantitative model of river basin bi-directional ecological compensation,a case study of the Xiaohong River basin in Zhumadian was conducted.First,Based on the measurement model of water resources value and pollution loss rate,the values of water resources and pollution losses from 2012 to 2015 were calculated respectively.In combination with the water resources of the river basin,the ecological damage compensation standards and compensation for the upper reaches of the basin were calculated.In addition,based on the pollution control cost model,the pollutant treatment cost for 2012-2015 was calculated.Combined with the amount of pollutant treatment,the ecological protection compensation standard and compensation amount for the upper reaches of the basin were calculated.Finally,the quantitative results of the bidirectional compensation of the river basin were analyzed and discussed. |
