- 海洋环境－已发表论文 
简要回顾了二氧化碳深海倾废设想提出的背景及其理论依据,阐述了实施二氧化碳深海倾废的可行性,着重讨论了CO2在深海的水合化过程以及最新的现场实验结果。分析了CO2海洋倾废对深海环境和生态系统的潜在影响。在与其他二氧化碳倾废方式进行比较的基础上,对今后的发展进行了展望。The greenhouse effect and climate change is being accelerated by the increased levels of carbon dioxide emission into the atmosphere, due to the combustion of fossil fuels. These phenomena are of world-wide environmental concern. A variety of schemes and hypotheses have been proposed to sequestrate carbon dioxide and to mitigate such increases. The deep ocean disposal of CO2 is one of these such hypothesis. This paper briefly reviews the origin and the theoretical basis of the idea on the deep ocean disposal CO2. The feasibility of carrying out this form of CO2 disposal is explored, with an emphasis on the hydration process of CO2 in the deep ocean and the newest in situ experiment results. The possible effects of the deep ocean carbon dioxide disposal on the environment and deep ocean ecosystem are analyzed. The research progress in this field is prospected on the basis of a comparison with other carbon dioxide sequestration schemes and hypotheses.
