Abstract

The invention discloses an environmental flow process regulation and control method based on runoff regime, water quality and biological multiple elements, which comprises the following steps: step 1,determining river ecological partitions, and identifying key runoff regime and water quality elements influencing a biocenosis; step 2, constructing a quantitative relationship among runoff situation, water quality factors and biodiversity indexes; 3, considering that the research river is a natural river or a regulation and control river, and if the regulation and control influence is severe, calculating the change rate of the biodiversity index under the regulation and control influence; if the research river is slightly influenced by gate dam regulation or is a natural river, directly carrying out the step 4; and step 4, perfecting and expanding evaluation indexes (including runoff situation, water quality factors and biodiversity indexes) and criteria of river health. And based on theactual measurement daily runoff process, environment flow process intervals under different water quality health levels are obtained. Technical support is provided for determination of a river environment flow process, influence of water conservancy project regulation and control on biocenosis and even river ecosystem protection.

Description

technical field

[0001] The invention relates to the field of river ecological environment protection, specifically an environmental flow process regulation method based on runoff situation, water quality and multiple biological factors, taking into account the influence of regulation and control of river basin gates and dams on the distribution of river organisms, and is mainly used for river ecological protection and restoration , Rational allocation of water resources, etc. Background technique

[0002] With the rapid development of the global economy and society, the river ecosystem has undergone significant changes under the influence of water resources development and utilization, hydraulic construction construction and regulation (dams, reservoirs, etc.), and excessive discharge of pollutants. Problems such as water pollution and ecological degradation are becoming more and more prominent, posing a serious threat to the health of river ecosystems and even global water ...
