摘要
对大连棒棰岛丘陵山地橡树、松树和灌木林春季和秋季土壤浅剖面有机碳含量和水含量测定与分析,结果表明,不同植物过程土壤碳含量和水含量有明显差异,松树林土壤碳含量和水含量总体上高于橡树和灌木林土壤,碳含量和水含量分布规律基本一致。相同植物过程土壤碳含量和水含量层次间有显著差异,有机碳含量和水含量分布又随土壤深度加深而呈下降趋势。相同植物过程秋季土壤含碳量和含水量高于春季土壤。
The contents of organic carbon and water in shallow soil profile, under the pine, oak and shrubbery forests, were measured and analyzed in Spring and Autumn at the hill in Bangchui Island of Dalian City. The results showed that there were obvious diversities of the contents of organic carbon and water in soil profile of different plant processes, the carbon and water contents of pine soil were higher than those of oak and shrubbery soils in the mass, and the distribution orderliness of the carbon and water contents was identical basically. The carbon and water contents of same plant processes were also different clearly, meanwhile the distribution of carbon and water contents presented a decrease trend with the increase of soil depth as a whole. The carbon and water contents of same plant processes in Autumn were higher than those in Spring as a whole.
