Abstract Combined with the work of “Three Lines One Permit” in China, this study constructed a corresponding index system, and selected Qingpu District of Shanghai as the case study area to evaluate the consistency of regional ecological carrying capacity and industrial layout by both single factor and comprehensive index methods. The results show that: 1) the single factor ecological carrying rate can reflect the key limiting factors, while the comprehensive index can directly show the cumulative impact of regional industries on ecological carrying capacity; 2) the conflict between industrial layout and ecological space and soil environmental quality is less in Qingpu District, but the contradiction between industrial layout and water, atmospheric environment is prominent, which results in the overload of ecological environment and the disharmony between ecological carrying capacity and industrial layout; 3) the regions with prominent consistency problems are basically the same as the key units of environmental control, indicating that the index system is objective and feasible, can provide reference for relevant evaluation and research work, and has the feasibility of nationwide promotion. It is suggested to strengthen pollutant emission control for the key control units.
