Due to the serious resource and environmental problems in urbanized areas, it is necessary to carry out a specific evaluation on their typical problems in the early-warning of the resource and environmental carrying capacity. However, most of the existing studies are too complicated to operationalize for practical use, and they lack consideration of the differences among development stages. According to the resource and environmental problems highlighted in the urbanized areas in recent years, we adopted an urban black-gray index of water and air environment as the specific indicator to reflect the comfort degree of habitat environment in urbanized areas at the present stage. Meanwhile, the key thresholds of urban black-odor water bodies and PM2.5 pollution days were determined in line with the major functions of the optimized and prioritized zones. Based on the above method, this article presented an empirical analysis on the urbanized area in the Beijing-Tianjin-Hebei region. Trial evaluation shows that, in the Beijing-Tianjin-Hebei urbanized areas, 47 districts or counties were in the severe warning category, 46 were in the moderate warning category, and only 11 were in the mild warning category. The severe-warning districts or counties were mainly concentrated along the Beijing-Guangzhou high-speed railway, and the distribution pattern was consistent with the regional distribution of major traffic lines and steel manufacture aggregation. The mild-warning districts and counties were mainly distributed in the northern Zhangjiakou-Chengde area and the eastern coastal areas, where the industries were relatively few and the geographic location was conducive to the rapid spread of pollutants. In summary, as an indispensable supplement to basic evaluation of resource and environmental carrying capacity for early-warning, the specific evaluation for urbanized areas can reflect the main constraints of these areas more clearly, and determine the early-warning status of different functional zones in different development stages objectively. The evaluation provides a scientific basis for urban spatial planning, urban development strategy research, and industrial structure adjustment in urbanized areas
