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 principles4.1 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. 4.3 The principle of comprehensiveness The investigation should be rigorous and thorough, without partiality, to ensure that the investigation data and conclusions can objectively reflect environmental pollution or ecological damage. condition. 4.4 Timeliness principle Intervene as soon as possible after environmental pollution or ecological damage occurs, start work as soon as possible, formulate investigation plans and monitoring plans in time, and obtain relevant information Data, conduct environmental monitoring, and obtain the data needed for identification and evaluation.5 Work content and work procedures5.1 Work content Ecological environmental damage investigation includes ecological environment baseline investigation, pollution source investigation, environmental quality investigation, biological investigation, and ecological service functions Survey, ecological environment restoration measures and cost survey, ecological environment restoration effect evaluation survey. 5.2 Working procedures The ecological environment damage investigation is divided into two stages. preliminary investigation and systematic investigation.
