摘　　要：自20世纪60年代沙漠历史地理研究创立以来,历史时期沙漠化成因一直是历史地理与第四纪学者关心的主要问题之一。由于研究材料、研究方法上的差异,早期历史地理学者多主张历史时期人类的不合理活动是半干旱地区沙漠化主要原因;第四纪学者则认为自然因素,尤其是百年尺度气候变化在沙漠化过程中发挥了主导作用。在不断的争论过程中,历史地理学与第四纪研究开始结合,对沙漠化成因的认识不断加深。近年来,区域内部地带性与非地带性的差异较好的解释了历史文献所记载的优越自然条件与第四纪剖面显示环境信息的不一致性,成为历史地理与第四纪融合的契合点。The essential geneses of desertification in semiarid area during the historical period have been the major research hotspot since 1960 s. 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zonality and non- zonality successfully explained the inconsistent of superior natural conditions recorded in historical documents and the arid environment showed in sediment profiles in the Quaternary.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.
