- Abstract:
-
Based on historical archives, lake sediment record and tree-ring data, the spatiotemporal distribution of the oasis of Heihe River and its historical desertification processes were examined in this paper. Then, the mechanism for the land use/cover change in historical period of this area was discussed. The results showed that: (1) the attention should be paid when using historical records to discuss the human impacts because the land and population records in historical archives are always inaccurate; (2) four processes of migration occurred in West-Han dynasty, Tang dynasty, Ming and Qing dynasties, and from 1949 to present, respectively, have greatly changed the land cover patterns, as a whole, the natural vegetation of this region was gradually replaced by irrigated agriculture; (3) the land use/cover change was dominated by natural processes before the Ming and Qing dynasties, nevertheless, current land use has been totally impacted by human beings.
