Research The Prehistoric Population And Cultivated Land Change In The Northeastern Margin Of Qinghai-Tibet Plateau

Population and cultivated land resources occupies an important position in thedevelopment of the society. They are the premise of human survival and continuance.In eastern Qinghai, prehistoric culture is inseparable from the population andcultivated land resources. Prehistoric population-land in east of Qinghai provinceresearch can let us more understand prehistoric human society and economicresources utilization pattern and intensity. Probe into interaction of the human societydevelopment and the environment, can provide reference for the sustainabledevelopment of modern society. Prehistoric culture of eastern Qinghai, occupies animportant position in the history of Chinese civilization. The population andcultivated land resources is the key of the study of prehistoric culture. There are agreat number of prehistoric cultural sites in eastern Qinghai and previousarchaeological research has accumulated a large number of first-hand data, with theresearch.Firstly, this article elaborates the selected topic basis, defines the area of thestudy and time series of the distribution of prehistoric culture in eastern Qinghai,illustrates the urgency and importance of research of population and cultivated landon the basis of enough data accumulated, which demonstrates the basis to research ineastern Qinghai prehistoric population-cultivated land.Secondly, we review theresearch at home and abroad in this paper，definite four basic approaches to the studyof the prehistoric population, and discuss the theory about the population research.The study of prehistoric populations is reviewed and summarized and the problemsexisting in the study of prehistoric population is discussed. We also look forward tothe sense of prehistoric population research. Thirdly, we elaborate the researchprogram, introduce the article research goal, and explain the research methods andtechnical route to be used in the study of this paper, according to research and featuresof research innovation in this paper, and the study of this article has carried on thefeasibility analysis. In view of the research, features of the research are presented inthis paper, and the study of this article has carried on the feasibility analysis. In this paper, before the calculation,we introduce the prehistoric culture inQinghai province in detail of the discovery of prehistoric culture, the distribution ofthe prehistoric culture, survival time of prehistoric culture, prehistoric culturecharacteristics and the economic form and etc.The method of prehistoric populationand cultivated land is combined the burial data analysis method with the settlementdata analysis method which adopted in the calculation of the population. According tocompared the two methods, we calculate the prehistoric populations. In research onprehistoric cultivated land, firstly, we take theory of mathematical model to calculatethe arable land area, then, used GIS tools to analyze, and finally rule out a part of thetheory of cultivated land area which is not appropriate to prehistoric, and chart thespace mapping of the cultivated land distribution pattern.Finally, according to the calculated results, we have carried on the thoroughdiscussion. The results show that, change of population and cultivated land in easternQinghai prehistoric culture is caused by climate change events in large composition.To explore the influence of environment on prehistoric culture influence, on theother hand, this article pointed out that the development of population and cultivatedland of prehistoric culture influence the existence of the environment at the same time.This suggests that: from the prehistoric, humans began to damage and impact on theenvironment which Puts forward the significance to contemporary society.
