Strengthening water quota management is a significant guarantee for the integrated control of water consumption in the areas of southern China with abundant water resource，and it is also an effective measure to improve the efficiency and benefit of the water use.Water quota is a dynamic index.Whether the water quota meets the daily management requirement of water resource and whether it is applicable to the practical situation of the current social and economic development are directly related to its implementation effect.The second version of the domestic water quota of Jiangxi province was revised and promulgated at the end of 2017.In order to understand the level of the new quota，combined with the typical survey of the domestic water consumption，the weighted average method was applied to compare the quota criteria at home and abroad with that in Jiangxi province.The Jiangxi province Water Supply Quota(DB36/T419-2017)was comprehensively assessed in terms of coverage，reasonability，advancement and practicality.Then，the existing questions were deciphered and the specific suggestions were put forward.This work would provide an important basis for improving the standard of domestic water quota in Jiangxi province in the future.
