Problems solved by technology

[0003] Although there are many methods for calculating ecological water demand at home and abroad, many methods have insufficient understanding of ecological water demand and its changing laws, and poor consideration of biological life cycles, which lead to unrestrained preemption of ecological water demand, causing a series of problems. Hidden dangers to the ecological environment have played a serious role in hindering the sustainable development of society and economy

Embodiment Construction

[0028] The present invention will be described in further detail below in combination with specific embodiments.

[0029] A method for calculating ecological water demand by coupling habitat adaptability and ecosystem health, comprising the following steps:

[0030] Step 1: Screening of dominant species:

[0031] The combination of density and biomass reflects a species' contribution to its community. In this invention, a dominance model is used to calculate the dominance of dominant species in river channels. Considering that the required ecological flow rate of each fish species is different, we introduce the following model in the calculation of ecological flow rate:

[0032] I mportance = ω 1 PCT abundance +ω 2 PCT biomass

[0033] Among them, I mportance Represents the dominance of a species, PCT abundance and PCT biomass Respectively represent the biomass and density of the species relative to the proportion of the entire community; ω 1 and ω 2 PCT abundanc...

Abstract

The invention discloses a method for calculating ecological water demand by coupling habitat adaptability and ecosystem health, comprising the following steps: screening dominant species; determining ecological flow velocity and ecological water depth considering habitat adaptability; determining ecological flow velocity and ecological water depth considering ecological health Water depth; calculation of ecological water requirements. The present invention avoids problems such as insufficient understanding of ecological water demand and its changing law, poor consideration of biological life cycle, unrestrained preemption of ecological water demand and other problems existing in many calculation methods, and the method is comprehensive, rational and accurate This provides a scientific basis for ecological restoration and scheduling for scientific researchers and government managers.

Description

technical field [0001] The invention relates to a method, in particular to a method for calculating ecological water demand by coupling habitat adaptability and ecosystem health. Background technique [0002] Ecological water demand is an important indicator of regional water resource allocation and an important evaluation basis for water resource management in river basins. Ensuring the necessary ecological water demand is fundamental and key to the ecological health of rivers. Therefore, the rapid and accurate calculation of the ecological water demand of the river is not only the basis and guarantee for the ecological restoration of the river, but also directly related to the consolidation and sustainability of the achievements of the construction of a water ecological civilization city. [0003] Although there are many methods for calculating ecological water demand at home and abroad, many methods have insufficient understanding of ecological water demand and its changi...
