This study examines the pollen evidence of vegetation change in the subtropical mountains in southeastern China based on three short sediment cores from the elongated peat-filled depressions in subalpine headwater zones from the Daiyun Mountain Range in central Fujian Province (approximately 25°40′N, 118°11′E).
根据采自福建省中部戴云山脉亚高山水系源头地带(大致25°40′N,118°11′E)泥炭沉积洼地的孢粉纪录,对该地区亚热带山地植被近4000年来的变化进行了研究。
