| 摘 要： | 针对土壤有机碳影响因素多且复杂而造成碳储量模拟模型中参数难以确定的问题,利用吉林西部167个典型土壤样点资料,通过统计分析对吉林西部表层土壤有机碳含量及元素地球化学进行了详细研究。结果表明:吉林西部土壤有机碳含量整体水平偏低,并存在着明显的区域分布特点,不同工作区的分异性不同;吉林西部土壤有机碳含量与Si含量、硅铝率、硅铝铁率和K含量之间存在着极显著的负相关,而与P、Al、Fe、Ca、Mg含量存在极显著的正相关;不同元素变异特征值可以解释土壤有机碳含量总变异的能力也不相同。通过研究土壤有机碳与元素含量的关系来定量研究土壤有机碳与土壤理化性质的关系是可行的,将二者量化关系与土壤有机碳储量模拟模型相结合,使得对土壤碳储量的认识更加科学。

| Abstract: | In order to resolve the problem of determining the parameters in carbon storage models caused by the multiple and complicated factors,we deal with the contents of soil organic carbon(SOC) and geochemistry characteristics of elements in west of Jilin Province by statistical analysis of 167 surface soil samples.The present results show that the overall level of SOC content in the study area is low and SOC spatical variability in the 3 working regions is quite different.The SOC content is apparently and negati... |
