近2 ka来东海内陆架泥质沉积物颜色反射率特征及其古气候意义
THE COLOR REFLECTANCE FEATURES OF THE SEDIMENTS IN MUD AREA ON THE INNER SHELF OF THE EAST CHINA SEA AND ITS PALEOCLIMATIC IMPLICATIONS FOR RECENT 2 ka
摘要
Abstract
A climatic proxy system is constructed on the basis of the color reflectance data of the core MZ01 using first derivative and factors analysis method, and a high-resolution climatic sequence is established with the support of AMS14C dating data for the past 2 ka. 900AD is the key turning-point in the course of climate evolution. Climate became significantly cold with high-frequency but low amplitude temperature fluctuation right after 900AD. In the past 2 ka,the climate in East China has experienced four stages including a cold stage before 580AD, a warm stage between 580 and 900AD, a temperature fluctuation stage between 900 and 1460AD and a cold stage between 1460 and 1880AD. Each stage includes some secondary regional or global temperature fluctuations.关键词
