摘　　要：重演历史时期贵州地区气候状况和石漠化演化过程。结合明清文献资料,对比分析织金洞石笋及鹅管的碳氧同位素记录进行研究。通过石笋ZJD—21和ZJD—9C的对比研究,证明不同洞穴沉积物的记录可以互相校准。古代文献资料能够客观准确的反映各地区气候现象,关于贵州省各个地区气候状况的历史记录并不完整。结果本研究从历史文献记录与织金洞石笋ZJD—21和鹅管ZJD—9C碳氧同位素的记录进行对比,证明该记录能够用来分析和探讨织金洞所在地区的历史气候状况。将1 240年至今的历史时期石漠化演化划分为孕育期、发生期、发展期、摇摆期和井喷期,探讨石漠化演化的时间序列,并加以描述,说明石漠化的发生发展主要受人为因素的控制。To repeat historical period Guizhou regional climate conditions and rocky evolution, the comparative analysis of the Ming and Qingzhi Jindong literature stalagmites and geese tube and oxygen isotope records were stud- ied. Through stalagmite ZJD-21 and ZJD-9C comparative studies have shown that different cave sediment records can be calibrated to each other. Ancient literature objective and accurate response to regional climate phenomena on climatic conditions in various regions of Guizhou Province＇s history is incomplete. In this study, historical documents and Zhi Jindong stalagmites ZJD-21 and goose pipe ZJD-9C oxygen isotope records in comparison to prove that the record can be used to analyze and explore Zhi Jindong area historical climate conditions. It is conclused that 1 240 historical period since evolved into rocky incubation period, the occurrence, the development period, rocking period and the blowout period of time to explore the rocky evolutionary sequence, and describe, illustrate the development of rocky controlled mainly by human factors.
