不同坡位对4种阔叶乡土树种叶片养分的影响
|
摘要
对木荷Schima superba、灰木莲Manglietia glauca、乐昌含笑Michelia chapensis、山杜英Elaeocarpus sylvestris在不同坡位的叶片养分含量和叶片化学计量进行了研究,以期揭示这些树种在不同坡位上的适应特征。结果表明:1)4个树种在上坡、中坡和下坡的叶片碳含量范围分别为483.58～527.36、501.99～507.58和473.85～527.18 g·kg~(-1),叶片氮含量范围分别为10.31～14.86、12.34～16.94和11.37～18.38 g·kg~(-1),叶片磷含量范围分别为0.65～1.05、0.82～1.14和0.93～1.44 g·kg~(-1);2)通常上坡的叶片氮、磷含量较低,同一树种不同坡位之间的叶片氮、磷含量大多差异显著;3)4种树种叶片C∶N高于全球平均水平,在上坡、中坡、下坡的分布范围分别为32.5～48.1、29.6～41.0、25.8～45.3;C∶P较低,在上坡、中坡、下坡的分布范围分别为500.1～766.0、439.9～614.0、329.6～557.0;N∶P在上坡、中坡、下坡的分布范围分别为14.0～16.4、12.9～15.1、12.3～16.8。
The leaf nutrients in four native tree species(Schima superba, Manglietia glauca, Michelia chapensis and Elaeocarpus sylvestris) were investigated and their stoichiometry were studied in Xiaokeng Forest Farm of Shaoguan City, Guangdong Province in order to reveal the adaptation characteristics of these tree species in different slope positions. The results showed that: 1) Leaf C content of four different tree species ranged from 483.58 to 527.36(uphill), 483.58 to 527.36(mid-slope) and 483.58 to 527.36(downhill) g·kg~(-1),uphill leaf N content ranged from 10.31 to 14.86, mid-slope 12.34 to 16.94 and downhill 11.37 to 18.38 g·kg~(-1), and P content(g·kg~(-1)) ranged from uphill 0.65 to 1.05, mid-slope 0.82 to 1.14 and downhill 0.93 to 1.44 g·kg~(-1), respectively. 2) Generally, the leaf nitrogen and phosphorus contents in uphill trees were lower than those of others, and mostly the leaf nitrogen and phosphorus contents of the same tree species at different slope positions had obviously differences each other. 3) Leaf C/N of the four tree species was higher than that of the global average level, ranging from 32.5 to 48.1 at upper-slope, 29.6 to 41.0 at middle-slope and 25.8 to 45.3 at down-slope,respectively; Leaf C/P in the four tree species was lower, ranging from 500.1 to 766.0 at upper-slope, 439.9 to 614.0 at middle-slope and329.6 to 577.0 at down-slope, respectively; Leaf N/P ranged from 14.0 to 16.4 at upper-slope, 12.9 to 15.1 at mid-slope and 12.3 to 16.8,at down-slope, respectively.
