Abstract
The coexisting strategies of plants under interspecific competition driven the trajectory of succession which concerned the ecological success of biodiversity maintenance in restored or created wetlands. To reveal the coexisting mechanism and guide the management of vegetation recovery, 220 vascular plants from 19 restored lakeside wetlands were systematically analyzed. The Ochiai index (OI) indicated that 62.41% of 435 pairs species exhibited negative correlation compared with 37.58% of positive correlation. The coexistence of heterospecific species was mainly accomplished via spatial and temporal niche partitioning, as well as trade-offs in height and coverage of plants. In terms of spatial niche partition, emergent plants were found to have a wider niche breadth of 1.67 ± 0.60 compared to upland plants with 1.28 ± 0.36. In temporal, 33.6% of species occurred in spring, 26.8% in autumn, and 39.5% in both seasons. Furthermore, according to plants phenology, the species maturing in spring, summer, and autumn accounted for 8.18%, 25.45%, and 62.27%, respectively. These findings on coexistence strategies can be used in the configuration of plants communities in both restored and created wetlands.
