palaeosol
解釋
古土壤-
Setenaly according to the analyses from selected profiles, we know that, it is cold and dry in this region during the early holocene when east asian winter monsoon ' s influence is obvious, so, it is a transition period from sand deposit to sandy soil deposit, when the layers become thinner gradually from north to south. during middle holocene, it is warm and humid, influenced evidently by east asian summer monsoon, so, it is an obivious pedogenesis, when there are generally well - developped holecene palaeosol ( so ) from north to south, and the pedogenesis in the south is better than that in the north, the soil is also thicker than that of the north. from late holocene to now, the climate changes to be dry and cold, but its changing scope is smaller than that of last glacial period
2 、就所選剖面分析來看，本區在全新世早期氣候回返，相對較寒冷乾燥，東亞冬季風影響較明顯，此時為沙層堆積向砂質土壤過渡，自北至南堆積的沙粒漸細；全新世中期氣候溫暖濕潤，東亞夏季風影響顯著，此時為明顯的成壤期，表現在自北至南普遍可見發育較好的黑壚土層，且南部的成壤作用比北部好，土壤的厚度也要大；全新世晚期至今，氣候向乾冷方向轉化，但變化幅度遠小於末次冰期。 -
