国内地质封存CO_2泄漏的生态影响研究

STUDY ON ECOLOGICAL IMPACT OF CO_2 LEACKAGE IN GEOLOGICAL STORAGE IN CHINA

以回顾CCUS技术在应对全球变化中的作用为基础,梳理了国内地质封存CO_2泄漏的生态影响研究方法,总结了CO_2泄漏对土壤及其微生物、植物与作物、水质及鱼类、陆生动物影响的研究进展,分析了CO_2泄漏对土壤、地表水和地下水等环境介质的影响,对植物及作物、土壤微生物、动物及鱼类等不同类型生命体的影响,以及CO_2泄漏生态监测指标筛选等不同领域研究的现状和问题;提出了地质封存CO_2泄漏对环境介质影响中的多因素、跨介质及流体流态影响机制,生态影响中的适应-抑制机制及指示性生态监测指标筛选,以及由室内外模拟到实施项目野外调查的研究方法转变三个方面的研究趋势。

Based on reviewing the role of CCUS technology in coping with global changes, in this paper, the research methods of ecological impacts of CO2 leakage in China domestic geological storage were combed, and the progress in environmental impact research of CO2 leakage on soil and its microbes, plants and crops, water quality and fish, and terrestrial animals were summarized;the status and problems in different research fields were analyzed, including impact of CO2 leakage on environmental media such as soil, surface water and groundwater, and on different living organisms such as plants and crops, soil microorganisms and terrestrial animals and fish, and screening of ecological monitoring indicators for CO2 leakage;the research trend of three aspects of geological storage CO2 leakage were proposed, including the mechanisms of multi-factor, cross-media and fluid flow in the influence of CO2 leakage on environmental media, adaptation and inhibition impact mechanisms of different living organisms and screening indicative ecological monitoring indicators in ecological impacts of CO2 leakage, and the transformation of research methods from indoor and outdoor simulation to field investigation of projects.
