Reconstruction of climate change using tropical peat deposit in Indonesia.

对印度尼西亚西爪哇Rawa Danau采集的泥炭岩芯(3.60m，7428cal.yrBP)进行了研究，以恢复与热带地区气候变化有关的过去植被和森林火灾。TOG、TN、这些同位素、含水率、元素碳等地球化学资料和岩心岩性的垂向剖面反映了该区的干湿旋回。木质素酚类植被指数显示了全新世中晚期以来的4次主要植被变化事件。元素碳剖面反映了同一时期发生的两次或三次大型森林火灾事件。泥炭岩芯的地球化学记录反映了过去8KYR期间植被变化和森林火灾频率对气候变化的响应。

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.
