摘　　要：初步探讨了微山湖红荷湿地16种植物间比叶面积(SLA)和叶干物质含量(LDMC)的差异。结果表明:SLA和LDMC在16种植物间存在显著差异(P<0.001),16种植物SLA和LDMC的变异范围分别为162.3~532.5 cm_(2)/g和0.12~0.35 g/g;SLA和LDMC在不同生活型间也存在显著差异(P<0.001),一年生草本植物的SLA显著高于多年生草本植物和木本植物的(P<0.001),而木本植物的LDMC显著高于一年生和多年生草本植物的(P<0.005);SLA和LDMC在挺水植物和陆生植物间差异均不显著;跨越16个物种,SLA和LDMC之间呈显著负相关关系(P<0.05)。The differences of Specific leaf area(SLA)and leaf dry matter content(LDMC)of sixteen species in the Red Lotus wetland of Weishan Lake were discussed.The results showed that there were significant differences in SLA and LDMC among the sixteen species(P<0.001),and the SLA and LDMC values of the sixteen species ranged from 162.3~532.5 cm_(2)/g and 0.12~0.35 g/g,respectively.There were also significant differences in SLA and LDMC among the plant life forms(P<0.001).The SLA of annual herbs was significantly higher than that of perennial herbs and woody plants(P<0.001),while LDMC of woody plants was significantly higher than that of annual herbs and perennial herbs(P<0.005).There were no significant differences in SLA and LDMC between hydrophyte and terrestrial plant species.There was a significant negative correlation between SLA and LDMC in the sixteen species(P<0.05).
