EFFECT OF CARBON SEQUESTRATION IN WETLAND: A case study of the Zhalong Wetland in Heilongjiang Province
-
摘要: 依据多目标区域地球化学调查成果，以扎龙湿地为对象，根据表层（0~20 cm）土壤与深层（150~200 cm）土壤样品有机碳含量分析结果，计算了研究区有机碳单位储量，研究了湿地土壤中有机碳的含量分布和变化特征，比较了不同土地利用方式间的土壤有机碳储量的差异，对比了20年来湿地土壤中有机碳储量的变化.结果显示湿地土壤中有机碳处于增加状态，说明湿地是“碳汇区”.Abstract: Based on the results of multi-objective regional geochemical survey, taking the Zhalong wetland as an example, the unit reserves of organic carbon are calculated by the analysis for surface(0-20 cm) soil and deep(150-200 cm) soil samples. With comparison of the organic carbon storages in different land use areas, the distribution and variation of organic carbon contents in the soil of wetland are studied. The changes of organic carbon in the wetland soil during the last 20 years reveal an increase in organic carbon reserves, showing a wetland carbon sink.
