2000-2023年关中平原城市群生态环境质量动态特征
Characteristics of ecological environment quality dynamic of the urban agglomeration in Guanzhong Plain from 2000 to 2023
摘要
Abstract
[Objective]The aims of this study are to timely grasp the ecological environment quality of the Guanzhong Plain urban agglomeration,to optimize the urban layout,and to build a civilization of ecological progress.[Methods]The Google Earth Engine(GEE)platform and MODIS dataset from 2000 to 2023 were utilized to construct a Remote Sensing Ecological Index(RSEI).The spatial variations,evolution trends,and future prospects of the ecological environment in the Guanzhong Plain urban agglomeration were analyzed.Additionally,the geographic detector was employed to examine the influencing factors and their interactions on ecological environment quality.[Results](1)Over the past 24 years,the overall RSEI of the Guanzhong Plain urban agglomeration had shown an increasing trend,with an average growth rate of 0.005 3/a.There were spatial-temporal variations in the RSEI evolution among different cities.In terms of spatial distribution,the ecological environment quality was lower in the Loess Plateau and rapidly urbanizing areas,while the vegetation-rich forest areas such as the Qinba Mountain maintained a higher level of ecological environment quality due to the comprehensive benefits of biodiversity conservation,water source conservation,and atmospheric environment protection.(2)Although there had been improvement in the ecological environment quality of the Guanzhong Plain urban agglomeration over the past 24 years,the proportion of high-quality areas was limited and showed a declining trend.The urbanization process had led to damage to the ecological systems in the central urban agglomerations,with the increased energy consumption,water scarcity,and pollution negatively impacting ecosystem stability.The targeted measures for ecological environment protection should be taken to address the specific needs and challenges of different regions.(3)The ecological environment quality of the Guanzhong Plain urban agglomeration was influenced by two dominant factors:urban nighttime lighting and slope.The former revealed a significant association between human activities and environmental effects such as resource consumption and carbon emissions.The latter directly impacted regional ecological stability by altering soil erosion,water conservation,and vegetation distribution patterns.The combined effects of these factors shaped the complex current state of the ecological environment.The interaction between precipitation and land use played a decisive role in the evolution of ecological environment quality in most years.[Conclusion]To maintain and enhance the ecological quality of the Guanzhong Plain urban agglomeration,integrating ecological conservation measures into urban planning should be considered.关键词
