The Record Of Millenarian Scale Global Change In The Holocene Black Loam

The aim of this research is undersanding the rule of millenarian scale cli-mate change in the faverable period of Holocene. The Research focused on thetwo main problems, which are quantitatively transfering the proxy data of pale-oclimate and paleoenvironment into a climate indexes as well as rebuilding andcomparing the hight resolution evolution sequence of paleoclimate and paleoen-vironment. Gained the quantitative relationship between the total ferrum oxidein morden deposite loess in the Loess Plateau of China and the local climatic in-dexes. Discussed the conditions and mechanism by which the relationshipformed. Studied the stable isotope feature of morden pollen and residue of plantin the Loess Plateau. Rebuilt the twelve hight resolution paleoclmatic se-quences of total ferrum oxide in the Holocene Black Loam. From the se-quences, we generalized three tapical model for the environment evolution ofthe Holocene faverable period, that is LuouChuan model, WeiNan model andDaTong model. Discussed the degree by which the tapical model have refleckedthe global change respectively. Describled the expresion form of millenarianscale global change rule in the Loess Platean of China, It is that on the back-ground of 10Ka scale climatic change there is an oscillation with a period of twothousand years and an amplitude corresponded to 1.6℃change of mean jan-uary temperature, or 70mm change of mean precipitation.
