Abstract:: According to the mathematical model,ecological water requirement and water deficit of wetland in the Hutuohe River Wetland were computed.The results show that the least ecological water requirement and water deficit are 4.93×10⁸ m³,2.20×10⁸m³ respectively,the proper ecological water requirement and water deficit are 8.87×10⁸～16.04×10⁸m³,6.14×10⁸m³～13.31×10⁸m³ respectively,and the most ecological water requirement and water deficit are 38.96×10⁸m³,36.23×10⁸m³ respectively.This paper also analyzed the issues on water safety in the study area.In the Hutuohe River Wetland there are some problems: obvious contradiction between the supply and demand of water resources,soil erosion and ecological degradation,shortage of water resources and water pollution,the low utilization rate of water resources with the waste of water and rural drinking water safety,the corresponding countermeasures are raised according to these issues.
