Technical Guidelines for Aquatic Ecological Health Assessment
1 Scope
This document stipulates the evaluation principles, work processes, evaluation objects and indicator systems and evaluation methods for aquatic ecological health evaluation:
This document is applicable to the health status assessment of freshwater ecosystems such as rivers (excluding estuaries), lakes, and reservoirs:
2 Normative reference documents
The contents of the following documents constitute essential provisions of this document through normative references in the text: Among them, the dated quotations
For undated referenced documents, only the version corresponding to that date applies to this document; for undated referenced documents, the latest version (including all amendments) applies to
this document:
GB 3838-2002 Surface water environmental quality standards
GB 15618-2018 Soil Environmental Quality Agricultural Land Soil Pollution Risk Management and Control Standards (Trial)
3 Terms and definitions
The following terms and definitions apply to this document:
3:1
The aquatic ecosystem is in a stable and sustainable state, with the ability to maintain its structural function, self-regulation, and the resistance and resilience to cope with stress:
ability:
3:2
A numerical value representing the health of aquatic ecology formed by the weighted summation of individual assignments of physical, chemical and biological indicators of the evaluation object:
4 Evaluation Principles
4:1 Systematic
The selection of evaluation indicators should reflect the health status of the aquatic ecosystem from physical, chemical, and biological dimensions:
4:2 Scientificity
Evaluation indicators should objectively and truly reflect the health of water ecology, with clear indicator meanings and standardized statistical and calculation methods:
4:3 Operability
Indicators should be selected based on indicators within the existing monitoring system or indicators that can be obtained using reasonable technical means, and the calculation method is simple:
Easy to do:
5 Workflow
The work flow of water ecological health assessment includes determining the assessment objects, clarifying the assessment indicator system, calculating and assigning assessment indicator values, calculating water
