宁南山区不同植被类型土壤生态化学计量特征与碳储量

Shuitu Baochi Xuebao
[目的] 为了阐明不同植被类型的土壤养分状况与固碳能力差异。[方法] [HTSS] 以宁夏南部山区具有代表性的乔木纯林(山杏林和刺槐林)、乔木混交林(刺槐+山杏)、乔灌混交林(山桃+柠条)、灌木林(沙棘)、草地共6种植被类型为研究对象,通过野外调查和室内分析相结合的方式,研究各植被类型0—100 cm土层的生态化学计量特征与碳储量。[结果] 研究区土壤C、N、P变化分别为19.74~35.11,1.74~3.19,1.60~1.69 g/kg,C、N均表现为随土层深度的增加而递减,其中刺槐+山杏林地的C、
