摘要: 遥感生态指数(RSEI)是一种能快速、实时、定量、多时序评估生态环境质量的评价生态指标,但RSEI在秋冬季节生态质量反演表征上存在不足。针对该问题,本文提出了一种适用于秋冬季节的RSEI。首先利用地理探测器分析RSEI的4个指标是否适用于秋冬季节的生态质量反演;然后采用植被覆盖度、植被健康指数、表层水分含量指数、地表温度、空气质量指数构建适用于秋冬季节的RSEI,并进行适用性验证;最后对三峡库区秋冬季节的生态环境质量进行反演与时空分析。结果显示:①库区生态环境质量总体呈现改善的趋势;②库区77%的面积生态环境质量较为稳定;③预测库区生态环境总体呈未来改善、持续性改善的趋势。

Abstract: RSEI is an ecological index that can evaluate ecological environment quality in a rapid, real-time, quantitative, and multi-temporal manner, while RSEI has the problem of inadequate inversion characterization of ecological quality in autumn and winter seasons. In response to this problem, a RSEI suitable for autumn and winter seasons is proposed. First, the four indicators of RSEI are analyzed by using geographic detectors to see if they are applicable to the inversion of ecological quality in the autumn and winter seasons. Then the vegetation cover, vegetation health index, surface water content index, surface temperature and air quality index are used to construct the RSEI applicable to the autumn and winter seasons, and the applicability is verified. The final inversion and spatio-temporal analysis of the ecological and environmental quality of the Three Gorges Reservoir area in autumn and winter show that: ①The ecological and environmental quality of the reservoir area show an overall trend of improvement; ②The ecological and environmental quality of 77% of the area is relatively stable;③The ecological environment of the reservoir area is predicted to show an overall trend of future and continuous improvement.

Key words: ecological environment, remote sensing ecological index, autumn and winter, the Three Gorges Reservoir area
