| 摘 要： | 研究了岷江上游干旱河谷/山地森林交错带高山栎林地、灌木林地、灌丛地、人工刺槐林地、花椒地和农耕地六种不同土地利用类型的土壤有机碳(SOC)和土壤水溶性有机碳(WDOC)分布特征。结果表明,不同土地利用类型SOC和WDOC的含量分别介于8.86～17.52 g.kg-1、84.41～192.80 mg.kg-1之间差异明显,人为干扰是导致不同土地利用类型土壤有机碳和土壤水溶性有机碳含量差异的重要原因。

| Abstract: | The changes in land usage lead to the release of carbon from terrestrial ecosystem,which is one of the major reasons that cause the continuously increased density of carbon dioxide in the atmosphere This paper analyzed the distribution characteristics of soil organic carbon(SOC) and water dissolved organic carbon(WDOC) under six kinds of land use types(including Quercus semicarpifolia secondary forest,shrubbery,shrub,Robinia pseudoacacia plantation,Zanthoxylum bungeanum forest and farmland and) at arid vall... |
