中文摘要	【目的】以渭干-库车河流域为研究靶区,探究人类活动对土地利用变化造成的影响,为干旱区土地资源利用与可持续发展提供科学依据。【方法】结合1990、2000和2014年TM遥感影像数据进行解译,研究流域内各土地利用时空格局的变化,通过主成分分析法和重心迁移模型,进一步分析人类活动对土地利用变化产生的影响。【结果】1990-2014年期间耕地和草地变化显著,耕地面积共增加1755.87 km~2,草地面积以每年255.70 km~2速度减少,耕地和草地动态度分别为3.23 %和-1.64 %,土地利用综合指数总体呈下降趋势;影响研究区土地利用变化的主要因素是人口和经济,25年来,人口重心累计迁移15.85 km,重心由西北向东南方向迁移,经济重心则是自西南向东北方向迁移。【结论】在当今社会经济的快速发展下,人类活动会对土地利用造成影响,人类活动强度的增大会导致耕地扩张和草地锐减,甚至退化,从而加深人地关系之间的矛盾,引发生态环境问题。
英文摘要	【Objective】Taking the Weigan-Kuqa river basin as the research target area,the impact of human activities on land use change is explored,which provides a scientific basis for land resource utilization and sustainable development in the arid area.【Method】Combined with the remote sensing image data of 1990,2000 and 2014,the spatial and temporal patterns of land use in the basin were studied.The principal component analysis method and the gravity center migration model were used to further analyze the impact of human activities on land use change.【Result】The cultivated land and grassland changed significantly during the period from 1990 to 2014.The cultivated land area increased by 1755.87 km~2,the grassland area decreased by 255.70 km~2 per year.The grassland and glacial dynamics were-1.64 % and-3.88 %,respectively,and the overall land use index showed a downward trend.The main factor affecting the land use change in the study area was population and economy.In the past 25 years,the population's center of gravity had migrated 15.85 km,the center of gravity moved from the northwest to the southeast,and the economic center of gravity had moved from the southwest to the northeast.Under the rapid development of today's social economy,human activities had an impact on land use.【Conclusion】The increase in the intensity of human activities will lead to the expansion of cultivated land and the sharp decline or even degradation of grassland,thus deepening the contradiction between human and land relations and triggering ecological and environmental problems.
