摘　　要：黄河流域生态保护与高质量发展是国家的重要战略,生态完整性评价是资源管理和环境保护的重要手段。本文从景观生态学角度,利用ArcGIS软件和地统计分析软件GS+9.0对太原2000年、2005年、2010年、2015年和2019年景观生态完整性进行评价,分析其时空动态与空间变异,揭示景观生态完整性时间动态变化规律以及空间演变规律,为太原的景观生态建设和景观生态规划提供依据。结果表明:①太原景观生态完整性偏低,且处于动态变化之中,从2000~2019年可分为三个阶段,2000~2010年完整性逐渐增强,2010~2015年完整性减弱,2015~2019年完整性又增强;②2000~2019年,均以中等完整性为主,从空间分布来看,各年东南部平原区及太原市区均属完整性较低区域;③从2005~2010年以及2015~2019年是两个主要变化阶段,均以低等完整性转化为中等完整性为主。太原景观生态完整性总的空间异质性较低,空间异质性主要是由空间自相关因素引起的。Ecological protection and high quality development is an important national strategy in the Yellow River basin,and ecological integrity assessment is an important means of resource management and environ⁃mental protection.From the perspective of landscape ecology,this paper originally evaluate the Landscape Eco⁃logical Integrity of Taiyuan in five years(2000,2005,2010,2015 and 2019)using ArcGIS software and statis⁃tical analysis software to GS+9.0,analyze the spatio-temporal dynamics and spatial variation of Landscape Ecological Integrity.Furthermore,the temporal and spatial variation laws of landscape ecological integrity were revealed,which provided the basis for landscape ecological construction and landscape ecological planning in Taiyuan.The findings indicated that:①The LEI of Taiyuan is relatively low and in dynamic change on the whole.From the perspective of the entire city,the LEI of Taiyuan is in a dynamic change.From 2000 to 2019,the LEI can be divided into three stages;②From 2000 to 2019,the area was dominated by medium integrity.From the perspective of spatial distribution,the southeastern plain area and the urban area all in the low value range;③From 2005 to 2010 and from 2015 to 2019,there are two main stages of variation,and both of them are mainly transformed from low to medium integrity;④The overall spatial heterogeneity of LEI is relatively low in Taiyuan,which is mainly caused by spatial auto-correlation factors.
