Abstract:

Using the countryside species-area relationship model, we estimated regional species loss for plants, mammals, birds, reptiles and amphibians as a consequence of land occupation from 2020 to 2100 under three SSP scenarios: the sustainable pathway (SSP1), the middle pathway (SSP2), and the fossil-fuelled development pathway (SSP5). We further developed new regional characterization factors (CFs) for 31 provincial-level regions in China and six land cover types. To address parameter uncertainties, we implemented Monte Carlo simulations and conducted sensitivity analysis using Borgonovo's method. Combined with the Life Cycle Impact Assessment (LCIA) approach, our regional characteristic factors can be used to quantify terrestrial biodiversity impacts due to urban construction land occupation. The resulting dataset includes: (1) projected species loss due to construction land expansion at provincial level (2020-2100); (2) province- and land-cover-specific CFs for assessing biodiversity impacts of future construction land expansion in China; (3) the value ranges of input parameters; (4) parameter importance (Borgonovo’s index) for species loss estimation; (5) parameter importance (Borgonovo’s index) for CF derivation; and (6) application case study: evaluating the terrestrial biodiversity impacts of newly added construction land. The dataset is archived in .xlsx format, and consists of one single file with data size of 146 KB. The research findings based on the dataset was published in Acta Geographica Sinica, Vol. 80, No. 7, 2025.
