| 摘 要： | 农业土壤有机碳密度和储量是全球变化及碳循环研究的重要问题。采用山东省第二次土壤普查数据,以土种为单位,对山东省土壤有机碳密度和总量进行了估算。土壤有机碳密度变化范围为38.50-0.77kgm-2,平均6.00kgm-2,低于全国平均水平;土壤有机碳总量为5.97×108t,约占全国总量的0.65%。土壤有机碳较高的土种基本上集中分布在山前平原、山间平原、山地平原交界处、滨海(湖)低平地等地质大循环过程中的物质堆积部位,土壤有机碳密度较低的土种分布在低山丘陵顶部、上部土壤侵蚀强烈的地形部位。

| Abstract: | Agricultural soil organic carbon density and storage is very important for global change and carbon cycle. Cited from the second general soil survey, the soil organic carbon density and storage of Shandong province were estimated by taking soil type as unit. Soil organic carbon density changed from 38.50 to 0.77kg m-2 with average of 6.00kg m-2, which is lower than the average of China. Soil organic carbon storage is 5.97×108t, 0.65% of the total of China. The soil local types of high organic carbon density are mainly distributed in the deposition place of geology cycle, such as piedmont plain, intermountain plain, and lowland of sea or lake. The soil local types of low organic carbon density are mainly distributed on upper places of hill with extensive soil erosion. |
