Determination method of marine ecological environment damage causal-relationships

Abstract

The invention discloses a determination method of marine ecological environment damage causal-relationships, and belongs to the technical fields of marine ecological environment protection and pollution damage identification and evaluation. The method includes 6 marine ecological environment damage causal-relationship chain model, 4 types of causal-relationship determination criteria and indicators with logical progressive relationships, a multi-type auxiliary evaluation model system architecture scheme matching the determination criteria, a marine ecological environment damage environment baseline and damage degree determination criterion and indicator system construction scheme of distinguishing regions, classes, items and levels and a quantitative determination method of damage degreesof the vulnerable factors and contribution of damage source items. A set of clear, simple, fast, systematic and effective causal-relationship determination technology support is provided for scientific determination of damage and consequences caused on marine ecological environments and human body health by sea-related-engineering, production and life pollution emission and suddenly occurring pollution events, identification, evaluation, blaming and compensation of damage and active and effective taking of countermeasures of prevention, preparation and disposal of pollution damage and environment restoration.

Description

technical field [0001] The invention relates to a method for judging the causality of marine ecological environment damage, which belongs to the technical field of marine ecological environment protection and pollution damage identification and evaluation, and includes: 6 kinds of causal relationship chain models of marine ecological environment damage, and four types of causality with logical progressive relationships Relationship judgment criteria and indicators, multi-type auxiliary assessment model system architecture plan matching the judgment criteria, marine ecological environment damage environmental baseline and damage degree judgment criteria and index system construction plan for zoning, classification and sub-item classification, and index system construction plan, damage degree of vulnerable factors and the quantitative judgment method of the contribution of the damage source item, in order to scientifically judge the damage and consequences caused by sea-related p...

AI Technical Summary

Problems solved by technology

[0017] 1. It is mainly applicable to the identification and evaluation of single and isolated damage events, and lacks the evaluation method of the superposition effect of multiple damage events;

[0018] 2. The main focus is on the damage to the ecological environment and its ecosystem service status, and there is a lack of assessment methods for the damage to the structure, process and function of the ecosystem;

[0019] 3. It is not matched and connected with the available auxiliary evaluation technology;

[0020] 4. Failure to consider the damage to the health of people exposed to ecological environment damage

[0023] Another example: Although the research on the formation of Enteromorpha green tide in the Yellow Sea confirmed that there is a relationship between species and space-time distribution between the green algae on laver rafts in northern Jiangsu, it ignored the large number of reclamation projects in Jiaozhou Bay and the Yellow and Bohai Seas. , leading to changes in water flow and scouring and silting conditions, as well as global climate change, etc., which affect the structure, process and function of the ecosystem.
