摘要:

内蒙古生态环境敏感脆弱,且地处华北上游,其生态环境质量对区域影响重大。针对近年来气候变化和经济快速增长带来的日益突出的生态问题,本文基于GEE平台,融合气溶胶光学厚度(AOD)和荒漠化差值指数(DDI),构建改进型遥感生态指数ARSEI,动态监测了2000—2023年内蒙古的生态环境质量,并分析了其空间自相关性。利用CA-Markov模型预测未来内蒙古生态环境质量。结果表明:(1)ARSEI指数的PC1贡献度超过87%,能够有效整合生态指标特征,与传统RSEI相比,更能准确反映内蒙古生态环境质量,具有较强的适用性。(2)2000—2023年,内蒙古地区的生态环境质量以较差和中等为主,空间上呈现自东向西递减分布趋势;2000—2005年退化较重,退化面积占比为21.18%,改善面积占比为8.11%,之后逐渐改善。(3)空间自相关分析显示,内蒙古生态环境质量具有显著的空间集聚性(Moran's I > 0.606),以高—高、低—低集聚为主;空间分布上各等级生态环境质量重心整体呈现自东向西、自北向南改善趋势。(4)预测结果显示,未来内蒙古中西部地区生态环境质量恶化风险高于改善潜力,应关注并采取有效措施遏制退化趋势。

Abstract:

Inner Mongolia is located in the upper reaches of the North China region, and its ecological environment is sensitive and fragile. In recent years, due to climate change and rapid economic growth, ecological environment problems have become increasingly prominent. Conducting ecological environment quality assessment and trend prediction in Inner Mongolia is of great significance for guiding ecological environment protection work. This article is based on the GEE platform, introducing aerosols (AOD) and desertification difference index (DDI), and constructing an improved remote sensing ecological index ARSEI to dynamically monitor and predict the ecological environment quality of Inner Mongolia from 2000 to 2023. The spatial autocorrelation of Inner Mongolia's ecological environment quality is discussed using spatial autocorrelation, and the CA-Markov model is used to predict the future ecological environment quality of Inner Mongolia. The results show that: (1) this article introduces the aerosol AOD and desertification difference index DDI to construct the ARSEI index, with a PC1 contribution of over 87%, which can better concentrate the characteristics of various ecological indicators, with little difference from RSEI, and the grading results are basically consistent. It can more accurately evaluate the ecological environment quality of Inner Mongolia and has strong applicability. (2) The ecological environment quality in Inner Mongolia from 2000 to 2023 was mainly poor and moderate, showing a decreasing trend from east to west in spatial distribution. The Inner Mongolia region experienced severe degradation from 2000 to 2005, with a degradation area accounting for 21.18% and an improvement area accounting for 8.11%. Since then, the ecological environment quality has gradually improved. (3) The global Moran index of Inner Mongolia for six years has been above 0.606, and the spatial agglomeration characteristics within the region are obvious, mainly distributed in high-high and low-low patterns. The overall trend of improving the ecological environment quality center of each level in spatial distribution is from east to west and from north to south. (4) The ARSEI prediction indicates that the ecological quality deterioration in central and western Inner Mongolia is slightly higher than improvement potential in the future. Therefore, it is crucial to prioritize ecological restoration projects in the ecologically fragile areas of this region.
