Method for calculating ecological water demand quantity of whole river reach

Abstract

The invention discloses a method for calculating an ecological water demand quantity of a whole river reach. The method comprises the steps of dividing the whole river reach into a plurality of areas; calculating nonconsumptive water demand quantity and consumptive water demand quantity in the areas; taking the maximum value of the calculated nonconsumptive water demand quantity corresponding to a plurality of hydrometric stations as the nonconsumptive water demand quantity of the whole river reach; adding up the calculated consumptive water demand quantity corresponding to the plurality of hydrometric stations, and taking a result as the consumptive water demand quantity of the whole river reach; and adding up the nonconsumptive water demand quantity of the whole river reach and the consumptive water demand quantity of the whole river reach and taking the result as the ecological water demand quantity of the whole river reach. According to the method for calculating the ecological water demand quantity of the whole river reach provided by the embodiment of the invention, the nonconsumptive water demand quantity and the consumptive water demand quantity of the hydrometric stations are calculated, the maximum value of the nonconsumptive water demand quantity of the hydrometric stations is extracted, the consumptive water demand quantity is added up and the two parts are added up to obtain the ecological water demand quantity, so the water demand quantity of upper and lower intervals is prevented from being calculated repeatedly, and a calculation result is relatively accurate.

Description

technical field [0001] The invention relates to the technical field of environmental protection, in particular to a method for calculating the ecological water demand of the entire river section. Background technique [0002] According to the different ecological functions, environmental functions and resource functions played by a certain amount of river water, river water can be divided into ecological water, resource water and disaster water. Water of a certain quality must be accumulated in the river system to maintain its normal structure and function, which is ecological water. There is a shortage of water resources in all major river basins in our country, and the high utilization rate of water resources has caused serious water environmental problems. How to rationally allocate the ratio of economic water and ecological water demand in the future water resource allocation is the key to realize the sustainable use of water resources and the restoration of water ecolo...
