中文摘要：

二氧化碳地质储存是减少二氧化碳排放的有效技术之一,但储存工作的安全性和持久性成为人们关注的重点.为了减少二氧化碳地质储存泄漏产生的对健康、土壤植被、地下水等的影响,开展二氧化碳地质储存环境风险评价研究非常必要.本文从评价原则、评价内容、预测方法等三方面阐述了二氧化碳的环境风险评价方法,并提出应急措施预案,为储存工程的实施提供了保障.

英文摘要：

CO2 geological storage is one of the most effective techniques to reduce CO2 emission, but the safety and durability become the focus of attention. In order to reduce leakage effect, including soil health, leakage effects of vegetation, groundwater, etc., the study of environmental risk assessment is very important. The author expounds the methods of enviranmental risk assessment from three aspects of evaluation principles, evaluation, prediction, and puts forward the emergency plans, providing guarantee for the implementation of storage engineering.
