中文摘要	以塔里木盆地南缘的于田绿洲为靶区,结合经典统计方法分析研究区灌漠土、棕漠土、盐土和风沙土的土壤有机碳、无机碳含量与环境因子的分异规律,利用冗余分析探讨了土壤有机碳、无机碳含量与环境因子的相关性.经典统计结果表明,研究区土壤有机碳、无机碳含量均值分别为2.51 g·kg~(-1)和25.63 g·kg~(-1),其中灌漠土的有机碳含量显著高于棕漠土、盐土和风沙土,风沙土的无机碳含量显著高于其他土壤类型;灌漠土的土壤含水量及养分含量最高,风沙土最低;除灌漠土外,各土壤类型盐碱化程度较高.冗余分析结果显示:环境因子对土壤碳含量影响的重要性排序为:全氮>有效磷>土壤含水量>地下水埋深>速效钾>pH>全盐.其中全氮、有效磷、土壤含水量和地下水埋深与土壤碳含量呈极显著相关性(P<0.01);速效钾、 pH与土壤碳含量表现为显著相关性(P<0.05);其他环境因子与土壤碳含量的相关性均不显著(P>0.05).
英文摘要	We analyzed the differentiation among the environmental factors and soil organic/inorganic carbon contents of irrigated desert soil, brown desert soil, saline soil and aeolian sandy soil by classical statistics methods, and studied the correlation between soil carbon contents and the environmental factor by redundancy analysis (RDA) in a typical oasis of Yutian in the southern edge of the Tarim Basin. The results showed that the average contents of soil organic carbon and soil inorganic carbon were 2.51 g·kg~(-1) and 25.63 g·kg~(-1) respectively. The soil organic carbon content of the irrigated desert soil was significantly higher than those of brown desert soil, saline soil and aeolian sandy soil, while the inorganic carbon content of aeolian sandy soil was significantly higher than those of other soil types. The soil moisture and nutrient content were the highest in the irrigated desert soil and the lowest in the aeolian sandy soil. All soil types had high degree of salinization except the irrigated desert soil. The RDA results showed that the impacts of environmental factors on soil carbon contents ranked in order of importance were total nitrogen>available phosphorus>soil moisture>ground water depth>available potassium>pH>total salt. The soil carbon contents correlated extremely significantly with total nitrogen, available phosphorus, soil moisture and ground water depth(P<0.01), and it correlated significantly with available potassium and pH(P<0.05). There was no significant correlation between soil carbon contents and other environmental factors (P>0.05).
