摘要: 为探讨新疆土地利用时空变化规律及驱动因子,以1990、2000、2010年的中国资源与环境科学数据中心的土地利用/土地覆被变化(LUCC)为基础数据源,借助IDRISI17.0的LCM模型和CA-Markov模型,并结合RS技术和GIS技术分析并预测研究区域20年间土地利用的空间转变。结果表明,20年间研究区耕地、建设用地、林地和水域面积增加,草地和未利用地减少;基于IDRISI17.0的CA-MARKOV模块预测新疆2025年土地利用状况,2010-2025年各地类总体上呈“一减五增”的趋势;在各影响因素中,人口数量的增长、经济的发展及环境政策的调整对研究区土地利用变化的影响更为显著。

Abstract: To study the space-time evolution and driving mechanism of land use in Xinjiang,based on data source of land-use and land-cover change(LUCC) form China resources and environmental science data center in 1990,2000 and 2010,the space-time evolution and driving mechanism of land use was analyzed and forecasted by IDRISI17.0 LCM model,CA-Markov model,and combined with RS and GIS. The results showed that the area of cultivated land,construction land,forest land and water increased,but the area of grassland and unused land decreased. Based on IDRISI17.0 CA-MARKOV model to simulate land use situation in 2025 in Xinjiang,the results showed that,on the whole,the area change of land tapes appeared “a land tape reduced and five land tapes increased” trend from 2010 to 2025. The increase in population,economic development and environmental policy adjustment to the influence of land use change was more outstanding in the study area.

Key words: CA-Markov Model, LCM Model, land-use change, Xinjiang
