摘　　要：微体化石组合很早就被用来进行海水古温度估算,近年来利用浮游有孔虫组合来估算古温度的方法有IK TF,MAT,RAM,SIMMAX,ANN和ANND等。本文介绍了这六种方法的主要原理和他们适用的纬度和温度范围,并分别利用FP12E、SIMMAX28及ANN等三类方法来估算冲绳海槽255站位、南海17957站位和ODP1143站位的表层海水古温度,比较计算结果的异同,以验证他们的适用性。Microfossil assemblages has long been used to estimate past sea surface temperature （SST）. In the past several decades, six methods including IKTF, MAT, RAM, SIMMAX, ANN and ANND were used to estimate SST with planktonic foraminifera assemblages. Here, we overview these methods and their suitable latitudes and temperature ranges. At last, FP-12E, SIMMAX-28 and ANN are applied to estimate the late Pleistocene SST of Site 255 in the Okinawa Trough, sites 17957 and 1143 （ODP-184） in the South China Sea, which indicate that FP-12E is quite useful in the northwest Pacific while the SIMMAX might be better in the low latitude, warm area such as the southern South China Sea.
