In order to scientifically analyse the relationship between human activities and biodiversity in the Loess Plateau, this paper seeks to provide a basis for biodiversity protection and ecological-environmental quality improvement in the Loess Plateau. The paper explores the features of the spatial and temporal differentiation of human activities by the virtue of the intensity model based on the remote sensing data of the land use in 2000, 2010 and 2018. Besides, with the combination of multi-source remote sensing data, the spatial relationship between human activities and biodiversity has been investigated via correlation analysis and bivariate spatial autocorrelation model, adopting the comprehensive biodiversity index constructed by the habitat quality, species diversity and landscape pattern index. The results show that:(1)The intensity of human activities in the Loess Plateau manifests an overall weakening trend between 2000 and 2018, given by the low intensity of human activities conducted in the west region divided by the axis of Taiyuan—Xi'an, whilst the east part takes the opposite.(2)The integrated biodiversity index remains basically stable and unchanged in the Loess Plateau from 2000 to 2018. In addition, the biodiversity obviously evidences the spatial heterogeneity with a spatial pattern of high in the northwest and low in the east.(3)A significant negative correlation in space can be concluded from human activities and biodiversity in the Loess Plateau from 2000 to 2018 which also presents a major spatial agglomeration effect between them, indicating that human activities have had a tremendously negative impact on biodiversity in this area. In conclusion, the biodiversity of the Loess Plateau was basically stable, but it was still greatly affected by the intensity of human activities.
