摘　　要：以Landsat影像为数据源,运用RSEI模型对郑尧高速郑禹段沿线两侧各6 km路域空间2004年、2013年和2020年生态环境展开动态评价,结合熵权法构建复合模型开展季相综合生态环境评价。结果表明:研究区RSEI指数夏季最高,其次是春季、秋季和冬季;生态环境质量空间变化最明显的是冬季,其次是春季、秋季和夏季,主要原因是耕地和森林受季节变化影响较大;耕地、建设用地与生态环境质量关联性最大,其次是森林、水体和草地;研究区2004年、2013年、2020年综合生态环境指数分别为0.5887、0.5202和0.5816,呈“先变差-再变好”的趋势;RSEI-熵权法复合模型可以有效开展高速公路路域生态环境质量综合评价,弥补单一季相生态环境评价的不足。研究内容可为区域生态环境综合评价提供技术支持,为路域空间可持续发展提供理论依据。Using Landsat imagery as the data source,the RSEI model is used to carry out dynamic evaluation of the ecological environment of the 6 km road area along the both sides of Zhengyu section of the Zhengzhou-Yaoshan Expressway in year 2004,2013 and 2020,and combining the entropy weight method to construct a compound model to carry out comprehensive seasonal ecological environment assessment.The results show that the RSEI index in the study area is the highest in summer,followed by spring,autumn and winter;the spatial change of ecological environment quality is the most obvious in winter,followed by spring,autumn and summer.The main reason is that cultivated land and forests are greatly affected by seasonal changes;cultivated land,construction land and ecological environment quality are the most relevant,followed by forests,water bodies,and grasslands.The comprehensive ecological environment indexes of the study area in 2004,2013,and 2020 are 0.5887,0.5202 and 0.5816,respectively,showing the trend of“first worse,then better”.The RSEI-Entropy weight method compound model can effectively carry out the comprehensive evaluation of the ecological environment quality of the highway area and make up for the lack of a single seasonal ecological environment.The research content of this paper can provide technical support for the comprehensive assessment of regional ecological environment,and provide theoretical basis for the sustainable development of road space.
