| Abstract: |
| Using statistic data and detailed inquisitional land materials from 1950 to 2008 and adopting Multivariate statistical
analysis and Literature survey, the mechanism and driving force of farmland changes and its ecological effects on Keriya Oasis of southern Taklimakan
Desert of China were analyzed. The results showed that:(1)The changes of farmland in Keriya Oasis within 1950-2008
went through three stages, from dramatic increase(within 1950-1961)→ to slow decrease(within 1962-1990)→to rapid increase(within 1991-2008). The total area of farmland was increased overall while the per capita area of farmland was deereased during the study period; (2)There were four main driving forces of the dynamic change of farmland in Keriya Oasis:government policy, economic development, population increase, and
progress in agrieultural techniques; (3)Farmland dynamics had improved the eco-environment of Keriya oasis to some extent. At same time, it also had resulted in a series of eco-environmental problems such as desertification of the outer of the oasis, salinization of the inner of the oasis, and wetland degradation and riverbed shortening, which was a potential threaten to the stability of the oasis. |
