Ecological Compensation Standard of Groundwater

Abstract

According to the characteristics of groundwater and the requirements of groundwater protection, the ecological compensation standard of groundwater is discussed. Based on the study of groundwater characteristics at home and abroad, combined with the existing ecological compensation research, the ecological compensation standard of groundwater is discussed based on fair water use. Based on the determination of water distribution, pollutant discharge permission and water use income, and based on the social equity mechanism and the cooperative game, the upper limit of agricultural water demand in Cheng’an County under the current development mode is calculated to be 400 million m3, the lower limit to be 34 million m3, and the average to be 32 million m3. The people’s Government of Cheng‘an county shall compensate the farmers for their water saving. The compensation standard is based on the economic benefits of agricultural water use. The total compensation amount is 236 million yuan. The compensation standard is 6720 ¥/ha according to the accounting of 35 thousand ha farmland area. The calculation results of the groundwater ecological compensation model are reasonable and easy to implement, which provides a theoretical basis for the implementation of groundwater ecological compensation in Beijing Tianjin Hebei region.
