Abstract

The invention discloses a drainage basin main stream dry water annual ecological water transfer method. The method comprises the steps that S1, the river water loss amount, the river loss per unit river length and the river loss rate of each section of a drainage basin source stream and a main stream in the drainage process are calculated through a water balance method; S2, according to a monthly minimum runoff method and a monthly frequency method, the minimum ecological water demand and the river runoff of each typical section are calculated respectively, and a Tennant method is used for calculating result evaluation; S3, based on a phreatic water evaporation model and an area quota method, water amounts required by vegetation growth of different sections are respectively calculated, and a mean value of two calculation results is taken as a vegetation ecological water demand of the sections; and S4, according to the river water loss amount, the river loss per unit river length, the river loss rate, the calculation result evaluation and the vegetation ecological water demand of the section, carrying out ecological water transfer in a low water year and ecological compensation between drainage basins, and converting the ecological benefit of the river water loss by adopting an economic value.

Description

technical field [0001] The invention belongs to the technical field of watershed ecological protection, and in particular relates to an ecological water diversion method for a main stream of a watershed in dry years. Background technique [0002] my country's water resources are short and unevenly distributed in time and space, which do not match the layout of economic and social development. The construction of water diversion projects is an important way to solve this problem. With the improvement of the development and utilization of water resources and the intensification of the contradiction between supply and demand, water diversion projects in some areas are gradually increasing and speeding up. In order to solve the external effects of water resources development, utilization and protection, the state attaches great importance to the implementation of water ecological compensation mechanism. Ecological scheduling is a general term for various river and water enginee...
