摘　　要：[目的]分析乌鲁木齐市生态用地的时空演化特征,特别是识别建设用地扩张与生态用地的冲突区域,对干旱区绿洲城市的生态用地保护、生态安全格局优化和区域可持续发展具有重要意义。[方法]基于乌鲁木齐市2000年、2010年和2020年土地利用数据,利用土地利用动态度、建设用地扩张速度及模式、识别生态源地并构建生态安全空间格局,对乌鲁木齐市建设用地扩张与生态用地的空间冲突进行分析。[结果](1)2000-2020年,研究区林地、草地、水域和建设用地面积总体呈增加趋势,分别增加160.51,451.17,47.58,805.19 km^(2),耕地和未利用地面积持续下降。(2)研究区建设用地面积加速扩张,其中米东区扩张最为显著,共增加230.62 km^(2),天山区建设用地扩张面积最小。(3)2000-2020年,乌鲁木齐市生态水平整体呈上升趋势,生态源地面积共增加611.52 km^(2)。(4)建设用地扩张与生态用地产生的空间冲突区域面积乌鲁木齐县最大,其次是米东区、沙依巴克区和水磨沟区,新市区则是无空间冲突区域。[结论]研究结果表明2000-2020年乌鲁木齐市建设用扩张与生态用地之间存在空间冲突。[Objective]Analyzing the spatial and temporal evolution characteristics of ecological land use in Urumqi city,especially identifying the conflict areas between construction land expansion and ecological land use,is of great significance for the protection of ecological land use,optimization of ecological security pattern and sustainable development of the region in arid zone oasis cities.[Methods]Based on the land use data of Urumqi city in 2000,2010 and 2020,the spatial conflict between construction land expansion and ecological land use in Urumqi city was analyzed by using the attitude of land use dynamics,the speed and pattern of construction land expansion,identifying ecological sources and constructing a spatial pattern of ecological security.[Results](1)From 2000 to 2020,the areas of forest land,grassland,watershed and construction land in the study area showed an overall increasing trend,increasing by 160.51,451.17,47.58,and 805.19 km^(2) respectively,while the areas of cultivated land and unutilized land continued to decline.(2)The accelerated expansion of construction land area in the study area was the most significant in Middong district,with a total increase of 230.62 km^(2),and the smallest expansion of construction land area in Tien Shan district.(3)In 2000-2020,the overall ecological level of Urumqi has shown an upward trend,and the area of ecological sources has increased by a total of 611.52 km^(2).(4)The area of spatial conflict between construction land expansion and ecological land use is the largest in Urumqi county,followed by Midong,Shayibak and Shuimogou districts,while the new urban area is a spatial conflict-free area.[Conclusion]The results of the study show that there is a spatial conflict between construction expansion and ecological land use in Urumqi during 2000-2020.
