Abstract: Data of human activity intensity can be used to assess the effects of human activities on biodiversity. Based on China’s land use/cover datasets and a land use-based index measuring human disturbance on ecosystem, we developed the dataset of human activity intensity (HAI) along the Yangtze River Economic Belt (YREB) for seven time periods, namely, late 1970s, late 1980s, 1995, 2000, 2005, 2010, and 2015. The dataset has a resolution of 1 km. The correlation coefficients of HAI and county-level population density data, and of HAI and gross domestic production (GDP) data are 0.615 and 0.709 respectively, indicating that the dataset is of good rationality. A validation against the global human footprint dataset indicates that the accuracy of our dataset is at least 26% higher than the global human footprint dataset. The dataset presented here can help deepen our understanding of the human-nature relationship, and provides statistical references for policymakers with regard to ecological conservation and economic development in YREB.
