Industrial heat sources in China during 2012 and 2023

A dataset of industrial heat sources in China from 2021 to 2023 including type information in vector format is first constructed and public free. The dynamic remote sensing monitoring results of industrial heat sources in China from 2021 to 2023 provide independent scientific basis for China to actively respond to the upgrading of the "structural adjustment and capacity reduction" industrial model, domestic and international carbon tax trading, and improvement of atmospheric environment and other sustainable development processes.

The results show that extending the time span to 2012-2023, combined with POI topology analysis based industrial heat source category recognition, can effectively reveal the spatiotemporal evolution laws of different types of industrial heat sources during the critical period of industrial transformation and upgrading; Based on the improved Kmeans industrial heat source recognition method, while ensuring recognition accuracy (98.14%), the number, accuracy, average particle size, and spatial coverage of industrial heat source recognition have been effectively improved; The dataset includes 20 characteristic parameters such as factory and mine locations, annual operating conditions, and categories, which fully record the radiation flux characteristics and production activity intensity of different types of industrial heat sources, providing richer data support for industrial carbon emission estimation and regional economic development assessment.
