摘要
///The Huguangyan Maar Lake (21°9′N, 110°17′E) is located 18 km southwest of Zhanjiang City, Guangdong Province. Lake sediment elementary analysis is carried by X-ray fluorescence spectrometer. Age model is obtained through comparison with previous study. Fe/Mn ratios, Rb/Sr ratios, Sr intensities and 550 ℃ loss on ignition (LOI) are good indicators of environmental change. Through high resolution investigation of above indicators, the authors reconstructed Holocene paleoenvironment evolution history of the Huguangyan area, paleoenvironment revolution at Huguangyan area since 11 000 cal a B.P. can be divided into four stages.
