Other claims from this paper (15)
- Observation Platycladus orientalis showed a single-peak diurnal pattern of net photosynthetic rate, unlike the other species.
- Observation The other five species showed a double-peak diurnal pattern of net photosynthetic rate.
- Observation Mean net photosynthetic rates across the six species ranged from 1.81 to 8.91 μmol·m⁻²·s⁻¹.
- Observation Leaf area index across the six species ranged from 1.37 to 2.56.
- Observation Elymus dahuricus had the highest mean photosynthetic rate and net assimilation per unit leaf area.
- Observation Platycladus orientalis showed relatively low mean photosynthetic rate and net assimilation per unit leaf area.
- Observation Elymus dahuricus was classed as Level I with strong carbon sequestration and oxygen release capacity.
- Observation Ailanthus altissima was classed as Level II with moderate carbon sequestration and oxygen release capacity.
- Observation Vitex negundo was classed as Level II with moderate carbon sequestration and oxygen release capacity.
- Observation Platycladus orientalis was classed as Level III with relatively weak carbon sequestration and oxygen release capacity.
- Observation Parthenocissus tricuspidata was classed as Level III with relatively weak carbon sequestration and oxygen release capacity.
- Observation Gleditsia microphylla was classed as Level III with relatively weak carbon sequestration and oxygen release capacity.
- Observation The artificially planted Elymus dahuricus showed superior carbon sequestration efficiency compared with naturally regenerated pioneer species.
- Observation Pioneer species had higher carbon sequestration capacity than Platycladus orientalis.
- Recommendation Elymus dahuricus should be prioritized in restoration practice and combined with Ailanthus altissima and Vitex negundo to maximize carbon sink benefits.
