摘要: 为明晰流域生态环境质量及其主要影响因素,本研究基于卫星遥感数据,通过耦合绿度、湿度、干度、气溶胶光学厚度4个指标,提出了改进的遥感生态指数(IRSEI)。采用IRSEI对滦河流域生态环境质量进行评价,并分析了影响流域生态环境质量的主要因素。结果表明: 2000、2008、2016、2022年,研究区IRSEI分别为0.488、0.532、0.563、0.586,流域整体生态环境质量持续上升,其中,东南地区相对较优、西北地区相对较差,并且东南地区生态环境质量改善而西北地区退化。年降水量、坡度、土地利用、第一产业以及第三产业是影响流域生态环境质量空间分异的关键因子,各因子的交互作用对流域生态环境质量的影响更显著。

Abstract: To clarify ecological environment quality and its influencing factors, we constructed an improved remote sensing ecological index (ISREI) coupled with greenness, humidity, dryness and aerosol optical depth based on satellite remote sensing data. We evaluated the ecological environment quality of Luanhe River Basin by IRSEI, and investigated the influencing factors. The results showed that IRSEI were 0.488, 0.532, 0.563, and 0.586 in 2000, 2008, 2016, and 2022, respectively, indicating that ecological environment quality of the basin continued to rise. The ecological environment quality and its change were characterized by high in southeast and low in northwest, improvement in southeast and degradation in northwest. Annual precipitation, slope, land use, primary industry and tertiary industry were the key factors affecting the spatial variations of ecological environment quality. The interaction of these factors had a more significant impact on the ecological environment quality.
