滇中亚高山5种林型土壤碳氮磷生态化学计量特征
|
摘要
探究不同森林类型林地土壤C、N、P含量及其化学计量特征的垂直分布情况对评价森林生态系统养分循环具有重要意义。本研究以滇中亚高山地区5种森林类型(常绿阔叶林(Evergreen broad-leaf forest)、高山栎林(Quercus semicarpifolia forest)、华山松林(Pinus armandii forest)、云南松林(Pinus yunnanensis forest)、滇油杉林(Keteleeria evelyniana forest))林地土壤为研究对象,对不同土层土壤有机碳(C)、全氮(N)、全磷(P)及其生态化学计量比的垂直分布特征进行分析。结果表明,不同林型、不同土层深度土壤养分含量及其化学计量比存在显著差异,5种林型各层土壤中C、N、P的变化范围分别为2.09-15.07、0.34-0.97和0.23-0.32 mg·g~(-1),各土层土壤C含量均表现为阔叶林>针叶林;各土层土壤N含量除30-40cm外均表现为阔叶林>针叶林;土壤P含量无显著差异。5种林型各层土壤C/N、C/P、N/P的变化范围分别为5.35-16.42、6.69-43.97和1.16-2.84,各土层土壤C/N均表现为云南松林和滇油杉林显著低于其他3种林型,C/P均表现为常绿阔叶林最高,N/P均表现为阔叶林>针叶林。5种林型土壤C、N、P三者间存在显著正相关,阔叶林土壤C、N、P三者间存在极显著正相关,而针叶林土壤C、N间存在极显著正相关,土壤P与C、N之间相关性则未达显著水平。
It is of great significance to study the vertical distribution of soil C, N and P content in soil layer and their eco-stoichiometric ratios in different forest types for evaluating nutrient circulation in forest ecosystem. The vertical distribution characteristics of organic carbon(C), total nitrogen(N), total phosphorus(P) and their eco-stoichiometric ratios at different soil depths in five forest types(Evergreen broad-leaf forest, Quercus semicarpifolia forest, Pinus armandii forest, Pinus yunnanensis forest, Keteleeria evelyniana forest) in central Yunnan were measured. The results showed that the contents of soil nutrient elements and their stoichiometric ratios were significantly different among different forest types. The variation range of C, N and P in each soil layer of the five forest types were 2.09-15.07, 0.34-0.97 and 0.23-0.32 mg·g~(-1), respectively, and the content of C in each soil layer was expressed as broad-leaved forest>coniferous forest. The soil N content of each soil layer(except 30-40 cm) was shown as broad-leaved forest>coniferous forest. There was no significant difference in P content. The variation range of C/N, C/P and N/P in each soil layer of the five forest types were 5.35-16.42, 6.69-43.97 and 1.16-2.84, respectively. The soil C/N in each layer was significantly lower than that in the remaining three forest types; C/P was the highest in Evergreen broad-leaved forest; while N/P was all expressed as broad-leaved forest>coniferous forest. There were significant positive correlations between soil C, N and P in five forest types. In addition, there were significant positive correlations between C, N and P content in broad-leaved forest. There was an extremely significant positive correlation between C and N content in coniferous forest, while the correlation between P and C or N content was not significant.
