黔西北地区优势树种叶片功能性状与经济谱分析
Analysis of relationship among leaf functional traits and economics spectrum of dominant species in northwestern Guizhou Province
摘要
Abstract
Expanded understanding of the leaf functional traits of the different dominant species in northwest Guizhou Province, and further analysis of their leaf economics spectrum contributes to reveal the relationship between plants and environments, and explain the methods of community assembly. Fourteen dominant species in northeast Guizhou Province were employed to investigate their leaffunction traits. The results were described as follows: leaf thickness was 0.12-0.60 mm, leaf area was 0.006-0.400 dm2, specific leaf area was 1.07-195.99 dm?2 g-1, leaf dry matter content was 27.41%-54.45%, relative water deficit was 11.09%-44.58%, and δ13C was from -3.12% to -2.71%. Leaf area was positively correlated with leaf dry matter content, and no significant correlation was found among other indexes. Leaf function traits were mainly affected by leaf dry matter content, relative water deficit and δ13C. These results showed that the existence of the leaf economics spectrum of dominant species in northwest Guizhou Province, the tree species tended to be slow investment-return species while the shrub species tended to be quick investment-return species, suggesting that the plants can take different adaptation strategies by the trades-offs among the economic traits. The paper is helpful to provide theoretical and practical basis for the restoration and protection of forest ecosystem in karst plateau and mountain areas.关键词
