GB/T 39791.2-2020 is Part 2 of the Chinese technical guidelines for identifying and assessing ecological and environmental damage, and covers the investigation. The investigation is where an ecological damage case is won or lost: the evidence is perishable, the baseline against which damage is measured usually has to be reconstructed after the fact, and a sampling design that a defendant can pick apart takes the assessment with it. The standard sets the investigation principles, the work content and procedures, the preliminary investigation, the systematic investigation, the quality assurance and quality control, and the summary and analysis of the information gathered, with informative annexes giving the assessment questionnaire and guidance on sampling surveys. It excludes damage from nuclear and radiological causes and took effect on 1 January 2021.

3 Terms and definitions

The following terms and definitions apply to this guide.

3.1 Environmental damage investigation Use scientific and systematic on-site surveys, monitoring, observations, interviews, aerial photography, data access and other methods to collect information and data to make a living The process of providing support for the assessment of environmental damage.

4 Investigation principles

4.1 Normative principles A procedural and systematic approach is adopted to standardize the investigation behavior. Professionals use nationally-recognized technical methods to conduct on-site investigations. Investigation and monitoring ensure the scientificity and objectivity of the investigation process. During the investigation, data and information collection, sample collection and transportation, The analysis and testing of samples shall be carried out in accordance with relevant technical specifications.

4.2 The principle of neutrality Investigation activities are not subject to interference from any department or personal factors. The personnel involved in the investigation should remain neutral and not be entrusted by the appraisal And other interference.
