Peat core (3.60 m, 7428 cal.yr BP) collected from Rawa Danau, West Java, Indonesia, were studied to reconstruct past vegetation and forest fire related in the climate changes in the tropical area. Vertical profiles for TOG, TN, these isotopes, water content, elemental carbon, other geochemical data and core lithology reflected dry and wet cycles in this area. The lignin phenol vegetation index shows four major vegetation change events since the mid-late Holocene. The profiles of elemental carbon reveals tow or three large forest fire events during same period. The geochemical records form peat core indicated the change of vegetation changes and frequency of forest fire in response to climate change during last 8 kyr.

研究了印度尼西亚西爪哇拉瓦达瑙地区的泥炭岩心（3.60 m, 7428 cal.yr BP），重建了热带地区气候变化中与植被和森林火灾有关的过去。TOG、TN、这些同位素、含水量、元素碳等地球化学数据和岩心岩性的垂向剖面反映了该区的干湿旋回特征。木质素酚植被指数反映了全新世中晚期以来的4次主要植被变化事件。元素碳分布揭示了同一时期两到三次大型森林火灾事件。泥炭岩心的地球化学记录显示了近8kyr来植被变化和森林火灾频率对气候变化的响应。
