| 摘要: |
| 通过巢湖南灵钻孔(ACN)的植硅体化石的系统研究,划分出六个植硅体组合带.并根据各植硅体组合带主要成分所反映的生态特征,结合主成分分析法(PCA),恢复了该区中全新世以来的古气候与古环境变化:自5600aBP以来气候划分为3个相对寒冷期(5600-5200aBP、4600-3600aBP、2500-2100aBP)和3个相对温暖时期(5200-4600aBP、3600-2500aBP、2100-1800aBP);并讨论了各个时期巢湖流域的环境变化. |

| Abstract: |
| According to systematic research on the phytolith fossils of core Nanlin in the Lake Chaohu，the phytoliths in the area can be divided into six zones. Based on changes in the main components in the phytolith zones and principal components analysis，the evolution of paleoenvironment and paleoclimate since the middle Holocene is reconstructed. There are three cold periods (5600 -5200 aBP，4600-3600 aBP, 2500-2100 aBP ) and three warm periods (5200-4600 aBP，3600-2500 aBP ,2100-1800 aBP ) since 5600 aBP. The environment changes of each period in the Lake Chaohu area were discussed compared with other areas. |
