生态环境监测与评价是提高生态环境质量的重要基础工作。本文以夏津县为研究对象,选取2010年和2020年2期Landsat卫星影像为研究数据,基于耦合NDVI、NDSI、WET、LST指标的生态环境质量评价指数RSEI综合分析评价研究区域2010年~2020年城...生态环境监测与评价是提高生态环境质量的重要基础工作。本文以夏津县为研究对象,选取2010年和2020年2期Landsat卫星影像为研究数据,基于耦合NDVI、NDSI、WET、LST指标的生态环境质量评价指数RSEI综合分析评价研究区域2010年~2020年城市化建设对生态环境的影响。结果显示:夏津县区域整体环境质量大幅度提高、城市及周边地区生态环境质量等级由第三级“良好”改善为第四级“优秀”、城区周边地区植被覆盖度提高、湿度指数提高、热度指数提高、干度指数下降。Ecological environment monitoring and evaluation is an essential foundational task for improving environmental quality. This study focuses on Xiajin County and utilizes two Landsat satellite images from 2010 and 2020 as the research data. Based on the integrated analysis of the Remote Sensing Ecological Index (RSEI), which couples NDVI, NDSI, WET, and LST indices, this paper evaluates the impact of urbanization on the ecological environment in the region from 2010 to 2020. The results show that the overall environmental quality of Xiajin County significantly improved. The ecological environment quality of urban and surrounding areas upgraded from the third level “Good” to the fourth level “Excellent”. The vegetation coverage around urban areas increased, the wetness index improved, the heat index rose, and the dryness index decreased.展开更多
