The essential geneses of desertification in semiarid area during the historical period have been the major research hotspot since 1960s.Because of the difference in research materials and research methods,the scholars of historical geography and quaternary have different opinions.Most historical geography scholars believed that irrational human activities was the major reason of desertification,However,most quaternary scholars insisted that climate change induced the desertification in history.Through this argument,Historical Geography and Quaternary began to integrate.The understanding of desertification was becoming deeper.The geographical zonality and non-zonality successfully explained the inconsistent of superior natural conditions recorded in historical documents and the arid environment showed in sediment profiles in the Quaternary.It became the junction for the integration of Historical Geography and Quaternary.
