英文摘要	Drought-induced plant hydraulic failure is expected to increase under climate change, and this negatively affects reforestation under the fragile karst environment in subtropical China. Compared with naturally regenerated forests, planted forests can rapidly increase vegetation coverage and have considerable economic benefits; however, their degree of resistance to drought-induced hydraulic failure is still unclear. Our study aimed to fill this knowledge gap by examining the differences in hydraulic characteristics between planted forests and naturally regenerated forests. Sample sites for both types of forest were selected in the humid subtropical karst region, and the hydraulic safety margin, stomatal conductance, and species-specific growing season length were measured for statistical analyses. The planted forest had a narrower hydraulic safety margin and presented a greater vulnerability to hydraulic failure than the naturally regenerated forest; however, it can bud later and abscise leaves early to avoid hydraulic failure. This study is the first to provide evidence of coordination between plant safety margin and species-specific growing season length in fragile karst ecosystems. To increase vegetation coverage and reduce soil erosion, the combination of both forest types could be an optimal ecosystem restoration strategy. Our study provides critical information for ecosystem restoration and management in subtropical karst areas.
