摘　　要：利用海洋生物碳酸盐硼同位素组成重建古海水pH的研究通常被称为δ11B-pH技术。近年来,该领域的研究取得了许多重要的成果。但由于理论上尚不完善,随着研究的深入,提出的问题也逐渐增多,如δ11Bcarb=δ11B4的假设能否成立,理论的α4-3值也尚未确定。本文综述了近年来的研究成果,重点讨论了海洋生物碳酸盐硼同位素恢复古海水pH三个主要理论基础的研究进展,展望了利用海洋生物碳酸盐硼同位素恢复古海水pH的前景。To reconstruct the pH values of the paleo-ocean water by using boron isotopic compositions of marine biogenic carbonate is usually called as the δ^11B-pH proxy technology. Recently, many important achievements have been obtained in the research of this technology. However, the more detailed studies have been undertaken, the more questions have been gradually pointed out due to the imperfection of the associated theories of this technology. For example, whether the assumption of δ^11Bcarb-pH B4 is correct or not,and the theoretical α4-3 value is not yet confined at present. This paper has comprehensively reviewed research achievements of this technology in the recent years, specially discussed advances of researches on the foundations of three kinds of theories for reconstructing pH values of the paleo-ocean water by using boron isotopic compositions of marine biogenic carbonate,and proposed the prospective of this technology.
