摘  要:
通过对沱江流域内江段土壤有机碳与其他要素相关性的分析研究表明:农田土壤中的有机碳与pH值相关性不显著,即pH值对土壤有机碳的多寡、分布及稳定性的影响不明显。土壤有机碳含量与S元素呈极显著相关性(0.869 1),与N元素呈显著相关性(0.800 1),与Se呈较显著相关性(0.649 77),且均为正相关,即S、N、Se含量增加,土壤有机碳含量也增加;与P元素呈不相关关系(0.053 9);与SiO2呈较显著负相关关系(r值为-0.530 7)。土壤有机碳含量与Cd,Zn,Pb,Hg元素呈较显著相关性;与有效B、有效Cu、速效K、水解性N、有效S、有效Fe的含量具有较明显的正相关性。

摘  要:
The analysis on correlation between soil organic carbon(SOC) and other factors in Neijiang section of Tuojiang River Basin is conducted.The results show that the differences in SOC of soil with different pH ware not significant,which means that pH doesn′t significantly affect the content,distribution and stability of SOC.SOC has a positively conspicuous correlations with S(R2=0.869 1) and N(R2=0.800 1),and has a positively significant correction with Se(R2=0.647 7).However,SOC is not correlative with P(R2=0.053 9) and has a negative correction with SiO2(R2=-0.530 66).As well,SOC has a positively significant correction with Cd,Zn,Pb,Hg,effective B,effective Cu,available K,hydrolytic N,effective S and effective Fe.
