英文摘要	The interactions between urbanization and the environment are crucial for sustainable urban development. To date, the key influencing factors and the interaction relationships between environment and cities remain unclear. We introduce a new method based on statistical analysis to identify the key factors that represent the interaction effects between urbanization and the environment and to quantify the interaction intensity in the Beijing-Tianjin-Hebei (BTH) megalopolis area. Grey relational analysis (GRA), two-way variance analysis and simple effect analysis are utilized. The main results are (1) Nine key factors covering water consumption, energy, land use, vegetation and pollutant treatment are identified. (2) Cities with heavy industry show higher interaction intensities than agricultural and tourism-based cities. (3) Pollutant treatment and water consumption show stronger environmental pressures on urban development than other factor types. For policy makers, pollutants and water should be carefully managed particularly in heavy industrial cities. This study will complement the assessment of ecological effects in megalopolis areas.
