| 【Objective】Specific leaf area (SLA) and leaf dry matter content (LDMC) are closely associated with plant growth and resource utilization efficiency. The inter- and intraspecific differences in SLA and LDMC of wetland plants can indicate the adaptation mechanisms of plants to wetland environments, and the research will provide a theoretical basis for the protection and rational development of wetland resources.【Method】The SLA and LDMC of 19 plant species in the Sanggou Bay National Wetland Park were measured, and the data were further compared with those collected in the Red Lotus Wetland of Weishan Lake in southwest Shandong.【Result】There were significant differences in SLA and LDMC among the nineteen species, and the coefficients of variation were 27.8% and 30.1%, respectively. Gramineae and Leguminosae species had lower SLA and higher LDMC. For the life form, the SLA of herbs was significantly higher than that of woody plants, while the LDMC was significantly lower than that of woody plants.
The emergent plants had significantly lower SLA and higher LDMC than that of terrestrial plants. There was a significant negative correlation between SLA and LDMC in different life forms. For the plant species distributed in both Sanggo Bay Wetland and Red Lotus Wetland, plants in the Sanggou Bay Wetland had lower SLA and higher LDMC.【Conclusion】The lower SLA and higher LDMC of plants in the Sanggou Bay Wetland were mainly induced by both the strong wind and poor soil in the region, reflecting that resource conservation strategies may be adopted for the plants in this area to adapt to the survival
environment. |
