Spatio-temporal Evolution and Driving Factors of Ecological Environment Quality in the Northern Foothills of the Qinling Mountains Based on RSEI

College of Geological Engineering and Geomatics, Chang' an University, Xi'an 710054, China

摘要

摘要: 为揭示秦岭北麓生态环境变化趋势，本文基于遥感生态指数RSEI模型系统评估2001—2022年间西安秦岭北麓生态环境质量，采用Sen + Mann-Kendall显著性检验、Hurst指数分析生态环境变化显著性及未来动向，运用地理探测器对该地区生态环境质量变化驱动因子进行了探究。结果表明：RSEI均值呈现“稳定-波动-攀升”三波段变化，年均增长0.00315，区域生态环境逐步改善；生态环境质量空间上呈现“南高北低”的特征，南部中低山区环境质量“显著改善”；未来秦岭北麓65.53%的区域生态环境将持续改善，年均气温、土地利用类型以及高程是影响秦岭北麓RSEI的最主要的驱动因素。地质环境作为本底条件深刻影响生态环境格局，土地利用类型转变是影响生态环境质量变化的重要因素，同时实施生态保护工程有效提升了生态质量，未来气候变化和土地利用模式仍是制约秦岭北麓生态的关键要素。

Abstract: To reveal the trends in ecological environmental changes in the northern foothills of the Qinling Mountains, this study systematically assessed the ecological environment quality of the Xi'an section of the northern Qinling foothills from 2001 to 2022 based on the Remote Sensing Ecological Index (RSEI) model. The Sen's slope estimator and Mann-Kendall significance test and the Hurst index were employed to analyze the significance and future trends of ecological environment changes, while the Geodetector was applied to explore the driving factors behind these changes. The results show that RSEI mean values exhibited a tri-phase pattern characterized by "stabilization, fluctuation, and ascent," with an average annual growth rate of 0.00315, reflecting a progressive improvement in the regional ecological environment. Spatially, ecological environment quality demonstrated a distinct "higher in the south, lower in the north" distribution, where the environmental quality in the southern mid-low mountain areas showed "significant enhancement." In the future, 65.53% of the northern foothills of the Qinling Mountains is projected to sustain ecological improvement. Annual average temperature, land use type and elevation were identified as the predominant drivers influencing RSEI variations in this region. The geological environment as the foundational condition, determines the ecological landscape. The transformation of land use types is a significant factor affecting ecological environment quality changes, while the implementation of ecological conservation projects has effectively enhanced it. Future climate change and land use patterns will remain key elements constraining the ecology of the northern foothills of the Qinling Mountains.
