Scope

Scope: This document specifies the selection of target indicators, technical processes, quality assurance and quality control, selection of benchmark values, benchmark verification methods, and modification and confirmation of recommended benchmark values for on-site verification of aquatic ecological benchmarks based on different ecological types and zoning of water environments. This document is applicable to guiding the on-site verification of aquatic ecological benchmarks in different ecological zones, including rivers, lakes (the general term for lakes and reservoirs), and estuaries. Main technical content: Based on the progress and development needs of water environmental benchmarks in China's river basins, a verification study of aquatic ecological benchmark thresholds in river basins is conducted to provide a basis for scientific verification of aquatic ecological benchmark thresholds in surface water bodies in river basins. Specific technical content includes: (1) Scope; (2) Normative reference documents; (3) Terms and definitions; (4) Selection of target indicators; (5) Technical processes and quality assurance; (6) Selection of benchmark values; (8) Benchmark verification methods; (9) Modification and confirmation of recommended benchmark values.
