The Research on Minimum Ecological Water Requirement for Wolong Lake in Liaoning Province

Minimum ecological water requirement of lakes has the significant function to maintenance the ecological function,coordinate social and economic water uses and ecological uses for lakes,realizes the scientific and sustainable utilization of the water resource.This paper makes the Wolong lake in Liaoning province as the research object,establishs the model for calculating the lowest ecological water level and the minimum ecological water consumption.Based on the observation meteorologic and hydrologic data,it is suggested that the suitable lowest ecological water level is 86.73 m,the average minimum ecological water consumption is 357.092 1×104 m3/a.
