The Analysis On The Environmental Changes And Man-land Relationship Of Southern Liaodong Peninsula In Holocene

This paper uses spore-pollen analysis and environment archaeology information, combining with 14C to recover the climate environment change within the last ten thousand years in southern Liaodong Peninsula province. The Chenshantou peat section is the high-time-resolution geological records which the environmental change and human activities of historical periods in southern Liaodong Peninsula district. According to the records, the authors we obtain a brand-new climate evolution rule of southern Liaodong Peninsula in the middle Holocene:7000-5000 a BP,the temperature was very high;5000-4000 a. BP,the Liaodong Peninsula climate changed from warm-wet to cold-dry;4000-3000 a BP,the climate changed warmly,the bronze culture developed;Through to the relevant discussion which moves to the climatic change and the humanity , it announces the mechanism that the environmental change has influenced to human development.The Holocene climatic changes, is one of the component of the world climatic changes, is a emphasis of the paleo climatic study, and is also an important content studied in the Quaternary environment. It is the environmental condition especially climatic condition that is the essential factor in the early cultural develop in southern Liaodong Peninsula . The dominating culture was prosperous in the warm period, and the simple livetook farming economy was in the low level in the cold period. Environment archaeology indicates: the warm-moist climate was the environmental foundation of the human society developed in Holocene. The study of the Holocene climatic change serial has achieved unified knowledge, which is the theoretic Holocene climatic change serial has achieved unified knowledge, which is the theoretic foundation to understand the relationship between paleo climatic change serial and prehistoric culture development stage. This paper intends to study the relationship between the climatic change serial and prehistoric culture development stage, the result shows that there is good relativity between them. About 7000-5000a.B.P, Xiaozhushan and Houwa culture developed rapidly within warming period, the agriculture achieved a relative high level, stock appeared, people had a stationary lifestyle, fishing, hunting and gathering were still the important economic means. which was the most steady warm-wet stage in Holocene Epoch. At about 5000-4000a.B.P, there was a cooling period, the climate change gave an import anti influence to prehistoric culture. Houwa culture conceiving many factors of civilized society was relatively backward. 4000-3000 a BP,the climate changed warmly,the bronze culture developed;Through to the relevant discussion which moves to the climatic change and the humanity , it announces the mechanism that the environmental change has influenced to human development.
