摘  要:
基于 Landsat8 的 2013、2017 和 2021 年 3 期遥感影像数据,采用熵权法构建了遥感生态指数(RSEI),对白洋淀及周边地区的生态环境质量进行了综合分析和评价.结果表明:①2013~2021 年,RSEI 上升了9.32%,研究区生态环境质量总体呈现"先下降后上升"的趋势;②2013~2021 年,除研究区东南部即任丘市生态环境质量较差以外,整体生态环境质量等级以良和优为主,生态环境质量高;③2013~2021 年,研究区生态环境质量变好面积占比 50.67%,变差面积占比 6.43%,生态环境质量整体呈上升趋势.研究结果证实加强生态环境保护的重要性,为今后的可持续发展提供参考数据.

摘  要:
Based on the remote sensing image data of Landsat 8 in 2013, 2017 and 2021, the remote sensing ecological index(RSEI) was constructed by entropy weight method to comprehensively analyze and evaluate the ecological and environmental quality of Baiyangdian Wetland and its surrounding areas. The results showed that:(1) From 2013 to 2021, RSEI increased by 9.32%, and the ecological environment quality in the study area showed a trend of "first decreasing and then increasing";(2) From 2013 to 2021, the ecological environment quality of Renqiu City in the southeast of the study area was poor, and the overall ecological environment quality was good and excellent, with high ecological environment quality;(3) The results confirm the importance of strengthening ecological and environmental protection and provide reference data for future sustainable development. From 2013 to 2021, the area with improved eco-environmental quality accounted for 50.67% and the area with decreased eco-environmental quality accounted for 6.43%, showing an overall upward trend. The results confirm the importance of strengthening ecological and environmental protection and provide reference data for future sustainable development.
