摘要: 环境质量指数(EQI)是由气候/气象、水资源、土壤、地形地貌和生物多样性等方面的环境要素组成的,能够快速全方位定量评估自然环境总体质量的工具。基于遥感、实地监测、文献等多源数据,用熵值法、主成分分析和层次分析等方法计算EQI,对2000、2010年和2020年塔里木河下游自然环境质量进行综合评价。结果表明:(1) 在生态输水作用下,2000—2020年塔里木河下游自然环境质量有显著改善。其中,EQI相对较高的区域主要分布在近河道两岸和湖盆周边。(2) 2000—2010年环境质量改善(改善面积为15620 km2)较2010—2020年(改善面积为13831 km2)明显。(3) 环境质量较差及以下(EQI<0.4)和较好(EQI≥0.8)等级的EQI的增加最为明显,而环境质量差(0.4≤EQI<0.5)和良好(0.6≤EQI<0.8)等级的EQI增加不显著。生态输水量的增加显著减少了EQI偏低和中等区域面积,促进了EQI偏高的区域面积增加,说明总体上生态输水改善了研究区环境质量。

Abstract:

The environmental quality index (EQI) is a comprehensive metric for evaluating the quality of the natural environment, integrating components such as climate, water resources, soil, topography, and biodiversity. Using data from satellite imagery, field observations, and published literature, EQI of the lower reaches of Tarim River, Xinjiang, China in 2000, 2010 and 2020 was calculated by entropy, principal component analysis, and hierarchical analysis methods. The findings revealed that: (1) Ecological water conveyance significantly improved the natural environmental quality in the lower reaches of Tarim River from 2000 to 2020. High EQI regions were primarily concentrated near riverbanks and the lake basin. (2) From 2000 to 2010, environmental quality improvement was more pronounced, with 15620 km2 increase in improved areas, compared to 13831 km2 increase from 2010 to 2020. (3) The EQI classified as poor (EQI<0.4) and very good (EQI≥0.8) increased significantly, whereas the below-average (0.4≤EQI<0.5) and good (0.6≤EQI<0.8) EQI classes showed no significant change. These results demonstrate the effectiveness of the overall ecological water conveyance strategy in enhancing environmental quality by reducing low and medium EQI areas and expanding high EQI areas.

Key words: environmental quality index, comprehensive assessment, multi-source data, lower reaches of Tarim River
