Abstract：To improve the information of agricultural alien plants in Enshi Prefecture,Hubei Province,the species composition,spatial distribution patterns,and environmental driving factors of agricultural alien plants in this region were analyzed by using field surveys and literature reviews.The results indicated that 134 species of agricultural alien plants existed in Enshi Prefecture,belonging to 89 genera of 36 families,with Asteraceae,Amaranthaceae,and Fabaceae being the dominant families.Among them,herbaceous plants were predominant,and annual herbaceous plants accounted for 47.0%.The analysis revealed that these plants were primarily driven by climatic conditions and anthropogenic introductions,exhibiting strong aggregation in gardens and cultivated land,which might lead to a decline in native plant species and a decrease in biodiversity in this region,posing a threat to the ecosystem's stability.This study improved the agricultural alien plants list and spatial distribution database in Enshi Prefecture,providing an important reference for ecological security risk prevention in this region.
