New progress of lake sediments and environmental changes research in China

Environmental change recorded by lake sediments is one of the important bra nches of the past global changes study. The new progress of lake sediments and environmental changes in China since the late 1980s has been comprehens ively discussed. The highlights emphasized are Asian paleomonsoon migration reflected by lake level fluctuation, uplift of the Qinghai-Xizang Plateau recorded by lacustrine sediments, saltlake sediments and environmental evol ution, lake response to the natural-human interaction and modern lake bioge ochemical process. Meanwhile important suggestions for the lake sediments a nd environmental research in the future are proposed, which include studies on the quantitative relationship between lake environment proxies and clim ate factors, high-resolution evolutionary sequence and spatial differentiat ion of environments, modern lake dynamic process and environment, Quaternar y Chinese lake database and global changes.
