Abstract:In order to reflected "difference fairness", we used the information entropy method to build the pollutant allocation index system and allocation model of a basin. Based on the allocation ratio of different areas and the total pollutant allocation in a basin, the quantity of pollutant allocation in different areas within a basin were determined. Taking the Minjiang River Basin as a case study, the ecological compensation standards values of the water environment from 2010 to 2019 were calculated based on the pollutant allocation in different areas of the Minjiang River Basin. The results showed that the actual COD discharges in Fuzhou city were higher 871 to 20857t than the theoretical COD discharges. Except for 2010, the value of COD discharges in Nanping city were lower than the theoretical COD discharges. The COD discharges in Sanming city were lower than the theoretical COD discharges, and the quantity of emission loss ranged from 1479 to 12507t. From 2010 to 2019, the number of ecological compensations in Fuzhou were 1175×104~28139×104 Yuan. Except for 2010, Nanping needed to pay ecological compensation (the compensation value was 821×104 Yuan). In other years, Nanping should receive ecological compensation from other areas with the compensation values ranged from 1253 to 13157×104 Yuan. Sanming should receive a ecological compensation values, ranging from 1996×104 to 16874×104 Yuan.
