Abstract:The challenges on water environment pollution are serious in Huaihe River Basin. The waste water discharge reached to 6461 million tons in 2018 and increased by 25. 9% than that in 2010. The water quality of the monitoring section with Grade Ⅳ, Grade Ⅴ and inferior Grade Ⅴ had still accounted for 36. 4% in 2019. Therefore, the comprehensive governance of water environment is significant for the green development in Huaihe River Basin. The main problems of the water environment governance are as follows: incomplete governance system, weak legal performance, simple governance method, imperfect trans-province water pollution control measures and deficient governance inputs. The corresponding countermeasures for the water environment governance in Huaihe River Basin are put forward, including improvement of planning system of water environment governance, intensifying of water quality conservation in water environment function areas, optimization of industrial structure and spatial arrangement, promotion of coordination of upper and lower reaches and transprovinces within Huaihe River Basin, strengthening of water environment monitoring and establishment of investing and financing mechanisms on water environment governance.
