| 摘 要： | 本文根据西太湖３．９６ｍ长湖泊岩芯沉积物的地球化学、微体古生物的综合分析，讨论了太湖距今１４００多年来的演化过程，结果表明：１４３００－１３０００ａＢＰ气候干旱，西太湖尚未形成：１３００－１１０３０ａＢＰ降水增加，湖泊形成，但气候偏凉；１１０３０－１０２００ａＢＰ是一个较显著的冷偏湿期，湖泊水位相对较深；１０２００－９５００ａＢＰ为一温干时期；９５００－７２００ａＢＰ是偏暖湿的过渡阶段，内部波动剧

| Abstract: | According to the analysis on TOC, TN, pigment, organic carbon isotope, HI and 14Cdating etc. obtained from the sediments of a 3. 96m - long core in West Taihu Lake. it is possible to understand the evolution of paleoenvironment during the last 14000 years in Taihu Lake. The results show that the evolution of paleoenvironment has undergone the following stages: Before West Taihu Lake was formed, there existed exposed feature from the proxies in 14300 - 13000aBP. reflecting arid paleoclimate, After the lake was formed,the cllmate got cool in 13000 - 11030aBP. All proxies showed a distinct cold and wetter climate in 11030 ~ 10200aBP. It was a warm and dry period in 10200- 9500aBP. and then turned into a transitional stage of warmer and wetter climate with drastic fluctuation. It was warm and wet during 7200 - 5700aBP. Some proxies changed violently in 5700~ 4900aBP,reflecting a probable interruption of sedimentation. The lake began to be eutrophic in 4900aBP or later. |
