Invasive alien plants (IAPs) present a severe threat to native ecosystems and biodiversity. Comprehending the potential distribution patterns of these plant invaders their responses climate change is essential. Parthenium hysterophorus , Americas, has become an aggressively invasive species since its introduction China in 1930s. This study aims collect reconstruct historical occurrence invasion P. . Using optimal MaxEnt model, geographical distributions were predicted based on screened occurrences environmental variables under current three future scenarios 2030s, 2050s, 2070s (i.e., SSP1-2.6, SSP2-4.5, SSP5-8.5), risk Chinese cities, croplands, forests, grasslands was assessed. The results show that: (1) initially invaded highly suitable areas further spread regions with non-analogous conditions. (2) Under climatic conditions, overall characterized by more southeast less northwest. Climate variables, including mean annual temperature (bio1), precipitation wettest month (bio13), isothermality (bio3), seasonality (bio4), are primary factors influencing distribution. (3) will expand scenarios, particularly toward higher latitudes. (4) Forests crop lands most serious Therefore, we suggest that government should strengthen monitoring management prevent protect agro-ecosystems human habitats. Depending areas, measures such as quarantine, removal, publicity be taken mitigate raise awareness prevention.
