选取京津冀地区作为研究区域，以人居环境适宜性作为研究对象，利用灰色关联分析综合评估经济系统、社会系统、气候系统、环境系统对2010-2020年城市人居环境质量的影响，同时利用灰色预测模型对未来几年京津冀地区人居环境适宜性进行预测。研究结果表明：2010-2020年京津冀人居环境综合适宜性指数的年均增长率为13.92%；经济系统、社会系统、环境系统适宜性发展总体呈上升趋势，而气候系统适宜性随时间呈波动发展；预测京津冀地区未来几年人居环境适宜性发展将维持稳定增长。

The Beijing-Tianjin-Hebei (BTH) region is chosen as the study area, focusing on assessing the suitability of human habitat from 2010 to 2020. This assessment integrates gray correlation analysis to evaluate the impacts of the economic, social, climate and environmental systems on urban habitat quality. Additionally, a gray prediction model is employed to forecast the suitability of human habitat in the BTH region for the upcoming years. Findings indicate an average annual growth rate of 13.92% in the comprehensive suitability index of the BTH human habitat during 2010-2020. The economic, social and environmental systems exhibit a consistent upward trend, while the climate system shows fluctuations over time. Predictions suggest continued stable growth in habitat suitability in the BTH region for the foreseeable future.
