Research on Habitat and Species Diversity of Spontaneous Plants in the Dujiangyan Canal Corridors

A comprehensive survey of spontaneous plants in the Dujiangyan Canal Corridors, part of the UNESCO World Heritage Site Mount Qingcheng and the Dujiangyan Irrigation System, reveals significant variations in species composition, diversity, and life forms across six distinct habitats. The study identified 257 plant species, with native plants comprising the largest proportion (42.02%). Hard revetment habitats exhibited the lowest species richness and diversity, likely due to anti-seepage materials used for irrigation efficiency. Conversely, wastelands showed the highest family, genus, and species richness. The research highlights the critical role of ferns in hard revetments and the adaptability of Papermulberry (Broussonetia papyrifera) in wasteland and self-use vegetable plot habitats, suggesting their potential for ecological restoration. These findings underscore the importance of habitat-specific plant community construction and dynamic monitoring to sustain biodiversity in irrigation areas.
