| description | The invention relates to a critical flow calculation method for maintaining biomass, wherein the method takes the biodiversity protection as the objective. The method comprises the following steps: building a relation between the biomass and a runoff volume; selecting a calculation time period; and calculating the critical flow. The method employs hydrologic year book data and fishery data in a synchronization series to build a flow-fishing amount synchronization change relation, and calculates the critical flow maintaining the biomass of a river under the condition that subjective factors are avoided. The invention provides the feasible calculation method for determining the critical flow corresponding to the river and achieving the safety management and regulation of the ecological safety of the river. The invention provides a scientific basis for protecting the biological integrity, avoiding the damage to the biological breeding conditions of the river, preventing the reduction of biomass, and preventing t |
