Comprehensive assessment of the coupling coordination degree between urbanization and ecological environment in the Siberian and Far East Federal Districts, Russia from 2005 to 2017 Ji Zheng1,2, Yingjie Hu3, Tamir Boldanov1,2, Tcogto Bazarzhapov1,2, Dan Meng1,2,YuLi1,2 and Suocheng Dong1,2 1 Institute of Geographic Sciences and Natural Resources Research, Chinese Academy of Sciences, Beijing, China 2 University of Chinese Academy of Sciences, Beijing, China 3 College of City Construction, Jiangxi Normal University, Nanchang, China ABSTRACT The urbanization growth in the 20th and 21st centuries has led to a series of unprecedented problems in the ecological environment. Based on constructing an integrated urbanization-ecological environment index system, this article conducts a comprehensive evaluation of the coupling coordination degree between urbanization and the ecological environment and uncovers its spatiotemporal variation characteristics in the Siberian and Far East Federal Districts, Russia from 2005 to 2017. The coupling coordination of urbanization and the ecological environment in the Siberian and Far East Federal Districts improve from slightly unbalanced development stage to barely balanced development stage from 2005 to 2017. In 2017, more than half regions achieved the barely balanced development of urbanization and the ecological environment. However, the most desirable development stage, the superior balanced development stage, is never achieved in the Siberian and Far East Submitted 4 December 2019 Federal Districts during the study period. The spatial pattern of the coupling 14 April 2020 Accepted coordination degree of urbanization and the ecological environment in the Siberian Published 15 June 2020 and Far East Federal District gradually changes from “dumbbell” to “high-north Corresponding authors ” Yu Li,
