三江并流区6种森林类型土壤化学计量特征研究
|
摘要
以三江并流区白桦林、川滇高栎林、丽江铁杉林、长苞冷杉林、山杨林、苍山冷杉林6种森林类型为研究对象,研究了6种森林土壤有机碳(SOC)、全氮(TN)、全磷(TP)含量及化学计量特征。结果表明,三江并流区6种森林类型土壤养分随着土层的加深而降低,其中C、N降幅比较大,普遍呈"倒金字塔"分布形式;P含量降幅比较小,呈"圆柱体"分布形式。6种森林类型土壤的C∶N值均高于中国土壤的C∶N平均值,6种森林类型所在区域土壤具有较高的N含量和较低的P含量,森林植被生长主要受P限制。取样地点受人为活动的干预较小,有机质、全氮等土壤养分要素空间分布体现出较弱的空间相关性,因此认为,三江并流区6种森林类型土壤养分的空间分布主要受结构性因素影响。
This paper studied the contents and stoichiometric characteristics of soil organic carbon( SOC),total nitrogen( TN) and total phosphorus( TP) in Betula platyphylla forest,Quercus aquifolioides forest,Tsuga forrestii forest,Abies georgei forest,Populus davidiana forest and Abies delavayi forest in the Three Parallel Rivers. while the decrease of P content was relatively small presenting as a"cylinder"distribution. The ratio of C and N contents of the six forest types was higher than the nationwide average value. The soil in the six forest types contained the rich N content and the lower P content which was the main factor restricting vegetation growth. The study site was less subject to intervention by human activities where the spatial distribution of soil nutrient elements such as organic matter and total nitrogen showed weak spatial correlation. It was considered that the spatial distribution of soil nutrients in six forest types in the Three Parallel Rivers was mainly affected by structural factors.
