在５０００ａ ＢＰ西北欧发生的Ｅｌｍ Ｄｅｃｌｉｎｅ，是全新世突发性环境事件或灾变过程的表现。它在６０年来一直是欧洲环境变迁，考古和＾１４Ｃ年代学界关心的热点论题，对其研究进展作了系统的评述，以了解其研究现状，促进我国全新世环境变迁和人地关系演变科学研究。

PROGRESS IN THE STUDIES OF THE ELM DECLINE IN NORTHWEST EUROPE

The Elm Decline took place in 5000 a BP in Northwest Europe is an abrupt environmental event during the Holocene.It has been considered as the natural record of a catastrophic changes and taken as a marker of the boundary between the Atlantic and the Subboreal since it was identified on the Holocene pollen diagrams in the 1930s.Because it happened Just at the time when Neolithic agriculture was initiated locally,it is then thought as the record of human impact,a mile-stone.in the course of the evolution of human-environment relationship. The Elm Decline remains to be an arguable topic even though it has been extensively studied by Quaternary palaeoecologists,archaeologists and(14)C chronologists for over 60 years. This paper intends to make an overall review on the progress in the studies of the Elm Decline in Northwest Europe,and also to introduce the work done in China in the purpose of promoting the research into the Holocene environmental changes and the human-environmental relationship in China.
