Compensation Function

Water resources in China’s river basins are scarce, and the pollution that shrouds them is serious. Constant disputes have emerged between the upstream and downstream sectors due to the contamination of river basins. Moreover, China’s research on ecological compensation mechanisms and compensation standards is still immature at present. Thus, this study establishes a compensation model and introduces the compensation coefficient K, including the compensation coefficient K1 between the upstream and downstream governments and the compensation coefficient K2 between the upstream government and the central government. This paper adopts the Bargain Game Model and obtains the value of K2 through the decision-making process between the central government and the upstream local government. In addition, amendment to the final offer arbitration law is used to acquire the value of K1 by proving the existence and uniqueness of equilibrium. Then, this paper takes the Taohe River Basin as an example and combines the compensation model to analyze, using the simplified compensation function to determine the amount of emission pollution from upstream to downstream and the compensation that upstream should receive.

Abstract. Surface wind speed decline in China has been widely reported, but its effects on hydrology have not been fully evaluated to date. In this study, the effects of wind speed change on hydrology are investigated using the Variable Infiltration Capacity (VIC) hydrological model for China during 1966–2011. Two model experiments, i.e. VIC simulations with the observed (EXP1) and detrended wind speed (EXP2), are performed over the major river basins in China. The differences between the two experiments are analyzed to assess the effects of wind speed decline on hydrology. Results show that wind speed has decreased by 29% in China. The wind speed decline have resulted in a decrease of evapotranspiration by 1–3% of mean annual evapotranspiration and an increase of runoff by 1–6% of mean annual runoff at most basins in China. The effect of wind speed on runoff and soil moisture is large in the northern basins where small change in hydrological conditions would have significant implications for water management. In addition, Wind speed decline has offset the expansion of the drought area in China. It has contributed to a reduction of drought areas by 8.8% of the mean drought area (i.e. approximate 10.6 × 104 km2 out of 1.2 × 106 km2) over China. The effect of wind speed decline on soil moisture drought is large in most basins in China expect for the Southwest and Pearl River basins.
