摘　　要：选取交通枢纽典型城市郑州市为研究区,以长时间序列Landsat系列遥感影像为数据源,通过构建遥感生态指数(remote sensing based ecological index,RSEI),对郑州市生态环境质量进行动态监测与评价.结果表明:近20 a郑州市生态环境质量得到明显改善,RSEI值由2000年的0.356上升至2020年的0.428,地表湿度和热量是主要影响因素.从空间重心转移来看,RSEI指标良、优等级重心向西北方向移动,逐渐靠近火车站、高铁站、飞机场等重要交通枢纽节点,说明郑州市交通枢纽城市建设和生态保护高质量统筹发展,促进了当地生态环境质量进一步提高.Zhengzhou,a typical transportation-hub city,was selected as the research area.Based on the longterm Landsat image data,a Remote Sensing Ecological Index(RSEI)was constructed to dynamically monitor and evaluate the ecological environment quality of Zhengzhou.The results show that the ecological environment quality of Zhengzhou City has significantly improved in the past 20 years,the RSEI value has risen from 0.356 in 2000 to 0.428 in 2020,and the main factors affecting the rise of the RSEI value are surface humidity and surface temperature.Besides,the shift of spatial gravity centers shows that the good-and-excellent-grade gravity centers in the RSEI index move to the city’s northwest,gradually approaching important transportation hub nodes such as railway stations,high-speed railway stations,and airports,which shows that the high-quality coordinated development of Zhengzhou’s transportation-hub-city construction and ecological protection has promoted the further improvement of the local ecological environment quality.
