新疆土壤有机碳与土壤理化性质的相关性
Soil organic carbon in relation to soil physicochemical properties in Xinjiang
摘要
Abstract
Analysing the relevance between variable soil physicochemical properties and soil organic carbon (SOC) content using soil data available from Xinjiang Uygur Autonomous Region will help us in farming using scientific fertilization and management of the Xinjiang soil.Significant and positive correlations were found between soil total nitrogen,cation exchange capacity,and the SOC content.Among them,the strongest correlation was between the quantity of SOC and total nitrogen (P＜0.0001,the determination coefficient R2=0.936 7).Soil pH and the soil bulk density showed negative correlation with SOC content (P＜0.05).The total phosphorus,total potassium,soil porosity,and soil organic carbon content was not significantly correlated (P＞0.05).The results can help to scientifically analyse the contribution and ecological significance of the soil ecosystem in arid areas in the global climate change scenario.关键词
