Comprehensive evaluation method for environmental quality of water ecosystem

An ecosystem and environmental quality technology, applied in general water supply conservation, data processing applications, instruments, etc., can solve problems that affect the accuracy of results, lack of standardized processing, and the inability of benthic animals to be objective about the water quality of various biological populations. To achieve the effect of objective method and reduce error

Problems solved by technology

[0006] The above-mentioned method has certain limitations. In the process of water ecological evaluation of rivers, only a single benthic animal cannot objectively and truly reflect the water quality conditions of various biological populations at different levels. Not standardized, it is very likely to affect the accuracy of the results

Embodiment 1

[0082]

[0083] Wherein, habitat quality is the index score after habitat quality standardization.

[0089]

[0095]

[0096] Habitat quality is a habitat quality evaluation value, and its significance is to reflect the habitat quality of the habitat.

[0101] Phytoplankton index=(Ss+S) / 2;

[0104]

[0106] Microbial Index=Sn

[0109] Fish index=(B+S+H+Ds+Dbp) / 5

[0112]

[0114]

[0116] Species Diversity Index

[0123]

[0128] Ss: the total number of species endemic to the statistical section

[0129] Through the above method, the comprehensive score value of the aquatic ecosystem can be obtained more accurately.

Embodiment 2

The scores are combined to correspond to the corresponding grades, so as to obtain the environmental quality status of the aquatic ecosystem.

Specifically, when evaluating the water ecosystem, the comprehensive score and the environmental quality of the water ecosystem

The corresponding relationship between the levels is as follows:

Abstract

The invention belongs to the technical field of water ecological environment monitoring, and particularly relates to a comprehensive evaluation method for environment quality of a water ecological system. The method mainly comprises the following steps: comprehensively scoring, specifically, acquiring the following five numerical values: a nutritive salt index, habitat quality, a phytoplankton index, a microorganism index and a fish index, and then calculating by adopting the following formula, the comprehensive score = (nutritive salt index + habitat mass + phytoplankton index + microbial index + fish index)/5; and evaluating the comprehensive score corresponding to an evaluation standard so as to obtain the environment quality condition of the water ecosystem. The method has the beneficial effects that five standardized indexes which can be used for the method disclosed by the invention are screened, and a comprehensive and comprehensive water ecological environment quality evaluation method is provided for the first time, so that the result obtained by the method is closer to the real situation of the water ecological environment.

Description

Comprehensive Evaluation Method of Environmental Quality of Water Ecosystem technical field The invention belongs to the technical field of water ecological environment monitoring, be specifically related to a kind of comprehensive evaluation of water ecological system environmental quality price method. Background technique [0002] The water ecological environment quality assessment method refers to describing the freshwater ecology through physical chemistry and biological integrity indicators Approaches to the stability, resilience, and sustainable states of composition, structure, and function of systems. [0003] Each river or each reservoir and lake will show its own regional characteristics, and the water ecological environment quality index It is a comprehensive evaluation index. If a unified standard is used for evaluation, there will inevitably be serious deviations, resulting in evaluation results. If it is inaccurate, it cannot reflect the true quality of ...
