东平湖湿地土壤有机碳分布特征及其影响因素
|
摘要
通过对东平湖湿地土壤有机碳含量进行测定,探讨了东平湖湿地土壤有机碳含量水平、分布特征及其影响因子。结果表明:东平湖有机碳含量的平均值为15.16 g/kg,范围为2.29～57.91 g/kg,空间分布差异较大,整体上表现为西北高、东南低的变化趋势;有机碳含量受区域、季节、深度以及区域与季节的交互影响;有机碳含量均值表现为芦苇区(27.29 g/kg)>养殖区(20.93 g/kg)>菹草区(17.65 g/kg)>混生区(10.97 g/kg);有机碳表层含量最高,并随着土层深度的增加而减小;夏季含量最高,春季最低;表层土壤(0～5 cm)有机碳含量与土壤容重呈极显著负相关关系,各区域土壤有机碳储量表现为芦苇区(1.95 kg/m~2)>养殖区(1.68 kg/m~2)>菹草区(1.47 kg/m~2)>混生区(0.90 kg/m~2)。
The distribution characteristics of soil organic carbon inDongping Lake wetland and its related influencing factors were discussed based on the measurement of the organic carbon content in the soil samples from different areas and seasons around Dongping Lake. The results show that the average of soil organic carbon content is 15.16 g/kg with the range from 2.29 g/kg to 57.91 g/kg, which indicates that there is significant spatial difference in organic carbon content in soils of Dongping Lake wetland. In general, the soil organic carbon content is higher in the northwest area than that in the southeast area of Dongping Lake. Soil organic carbon content is affected by the area, season, depth and interaction of area and season. The mean of soil organic carbon content in different areas decreases in the following order: P. australis area(27.29 g/kg) > aquaculture area(20.93 g/kg) > P. crispus aera(17.65 g/kg) > nearshore waterweeds area(10.97 g/kg). Soil organic carbon content is significantly higher at the soil layer of 0～1 cm than at the other soil layers and generally decreases with the increase of depth. Moreover, the soil organic carbon content is the highest in summer and the lowest in spring. There is a significantly negative correlation between soil organic carbon content and soil bulk density(p<0.01). The storage of soil organic carbon in different areas decreases in the following order: P. australis area(1.95 kg/m~2) > aquaculture area(1.68 kg/m~2) > P. crispus area(1.47 kg/m~2) > nearshore waterweeds area(0.90 kg/m~2).
