[目的] 研究天山北坡城市群土地利用及生态服务价值（ESV）的时空演变特征，为该区生态服务功能改善和生态景观建设提供理论指导。[方法] 基于2000，2010，2018年天山北坡城市群的土地利用数据，利用遥感、空间统计分析方法，分析天山北坡城市群土地利用动态变化和生态服务价值的时空演变特征，并采用景观指数模型研究了天山北坡城市群ESV的景观格局变化。[结果] ①天山北坡城市群主要用地类型为未利用地和草地，建设用地的单一动态度变化最大，动态变化幅度达2.7%；土地利用转移变化主要发生在耕地、草地、建设用地、未利用地之间，以草地向耕地和建设用地转入最为突出。②近20 a研究区ESV总量从1 410.76亿元减少到1 400.17亿元，共计损失10.59亿元，整体呈下降趋势；其中支持服务的ESV减少最多。③研究区ESV呈现出西北部和中部高，北部和东南部低的空间格局；2000-2018年研究区ESV景观格局发生显著的变化，低、中、高ESV区的景观格局表现为研究前期破碎异质化，后期集聚同质化。[结论] 针对不同等级的ESV区，天山北坡城市群的生态环境恶化，需要采取不同的措施改善其生态服务价值，降低城市群发展对生态环境造成的破坏，推动区域生态景观的建设。
[Objective] The temporal and spatial evolution characteristics of land use and ecological service value (ESV) in the urban agglomeration on the northern slope of Tianshan Mountains were studied in order to provide theoretical guidance for the improvement of ecological service functions and the construction of ecological landscape in this area.[Methods] Based on the land use data of the urban agglomeration on the northern slope of the Tianshan Mountains in 2000, 2010, and 2018, the characteristics of the land use dynamics and the ecological service value of the urban agglomeration on the northern slope of the Tianshan Mountains were analyzed using remote sensing and spatial statistical analysis methods. The landscape index model was used to explore the landscape pattern changes of the urban agglomeration on the northern slope of Tianshan Mountain.[Results] ① The main types of land used in the urban agglomeration on the northern slope of Tianshan Mountains were unused land and grassland. The dynamic change of land use for construction land was the largest. The land use transfer mainly occurred from grassland to cultivated land, cultivated land and unused land. And the transfer from grass land to cultivated land and construction land was the most prominent. ② The total amount of ESV in the study area in the past 20 years decreased from 141.176 billion yuan to 140.017 billion yuan, with a total loss of 1.059 billion yuan. The overall trend was declining, and grassland had the most ESV loss. ③ The ESV of the study area presented a spatial pattern of high in the northwest and middle, and low in the north and southeast. the ESV landscape pattern of the study area changed significantly from 2000 to 2018, and the landscape pattern of the low, medium and high ESV density areas was characterized by fragmentation and heterogeneity in the early stage of the study, and the homogeneity of agglomeration in the later stage.[Conclusion] The ecological environment of the urban agglomeration on the northern slope of the Tianshan Mountains is deteriorating. For different grades of ESV areas, different measures need to be taken to improve the ecological service value of the study area, reduce the damage to the ecological environment caused by the development of the urban agglomeration, and promote the construction of ecological landscape.
