摘　　要：天山北坡是西北地区重要的生态功能区和重要经济带,受气候变化和人类活动的影响,脆弱的生态环境面临着巨大挑战,但目前对该地区生态环境质量时空变化、特征及驱动力的认识较少。为此,本文利用改进型遥感生态指数(ERSEI)、空间自相关分析、多元线性回归分析和地理加权分析方法揭示天山北坡1990、2000、2010和2020年4个时期生态环境质量时空变化、特征及其驱动因素。结果表明:(1)1990-2020年天山北坡ERSEI先大幅下降后逐渐恢复并持续上升,生态环境质量逐渐改善并趋于稳定,总体呈“东优西劣”的空间格局;(2)天山北坡生态环境对气候变化较为敏感,温度是ERSEI变化的最重要驱动因子;(3)不同驱动因素对ERSEI的影响存在显著的空间异质性,自然因素对局部ERSEI空间分异起主导作用,人为因素则对年际ERSEI变化产生重要影响。这表明气候变化和人类活动显著影响ERSEI变化,未来应科学规划各类经济活动,减缓气候变化效应,提升天山北坡生态安全和环境可持续性。The northern slope of Tianshan Mountains is an important ecological functional area and a major economic zone in Northwest China.Due to the impacts of climate change and human activities,its fragile ecological environment has been facing great challenges,whereas there is limited knowledge of spatiotemporal changes,characteristics,and driving forces of ecological environment quality in this region.Therefore,this paper utilizes the enhanced remote sensing ecological index(ERSEI),spatial autocorrelation analysis,multivariable linear regression model,and geographically weighted analysis to reveal the spatiotemporal changes,characteristics,and driving factors of ecological environment quality on the north slope of Tianshan Mountains in four periods:1990,2000,2010,and 2020.The results show that:(1)from 1990 to 2020,the ERSEI of the north slope of Tianshan Mountains first significantly declined,then gradually recovered and continued to rise.The ecological environment quality gradually improved and tended to be stable,with an overall spatial pattern of“superior in the east and inferior in the west”;(2)the ecological environment of the north slope of the Tianshan Mountains is more sensitive to climate change,and temperature is the most important driving factor for the change of ERSEI;(3)There is significant spatial heterogeneity in the effects of different driving factors on ERSEI.Natural factors play a dominant role in local spatial variability,while anthropogenic factors exert an important influence on the interannual variability.This suggests that climate change and human activities have significantly affected ERSEI changes.In the future,various economic activities should be scientifically planned to mitigate the effects of climate change,and enhance the ecological security and environmental sustainability of the north slope of the Tianshan Mountains.
