本文根据雄县地热田钻孔的古土壤、孢粉分析和地层层序揭示第四纪以来该区土壤层及淋溶淀积作用可划分二大带。0~420m:从上到下土壤颜色加深,淋溶淀积加强,出现团块状钙质,古气候由老至新从温湿转化为现代干冷;420~800m:淋溶淀积作用较强烈,上部地层显示过湿的气候条件,反映古气候从干热向温湿转变。第四纪以来植被发展曾经历了4个大的阶段,冷暖干湿气候交替有16次明显变化
Based on the paleosol, sporopollen analysis and stratigraphic sequence of the boreholes in Xiongxian geothermal field, this paper reveals that the two major strata can be divided into the soil layer and the leaching and depositional facies since Quaternary. 0 ~ 420m: From top to bottom, the color of soil is deepened, the leaching and deposition are strengthened, and the massive calcareous mass appears. The paleoclimate changes from warm and wet to the dry and cold in ancient times; 420 ~ 800m: , The upper strata showed too wet climatic conditions, reflecting the ancient climate change from dry heat to warm and humid. Quaternary vegetation has experienced four major stages of development, cold and wet climate alternately 16 significant changes
