过去18ka云南天才湖硅藻重建温度和降水量数据（公元前15836年-2007年）

在我国云南西南地区天才湖获取岩芯样品，利用硅藻标准分析鉴定方法，获取高分辨率生物硅藻指标序列；通过增强回归树和加权平均回归转换函数模型方法，建立现代湖泊硅藻与温度/降水量记录转换函数，重建夏季温度和年均降水量

Core samples were collected from Tiancai Lake in southwestern Yunnan Province, China. High-resolution diatom proxy records were obtained using standard diatom analysis and identification methods. Transfer functions between modern lake diatoms and temperature/precipitation records were established via boosted regression trees (BRT) and weighted averaging regression transfer function models, and summer temperature and mean annual precipitation were reconstructed.
