摘要：

以黑龙江省扎龙湿地及其周边地区多目标区域地球化学调查、第2次土壤普查数据为基础，通过不同土地利用方式下土壤全碳、有机碳密度、储量的估算，研究该地区20 a来土壤碳库的变化趋势。结果显示：扎龙沼泽湿地区0~100 cm土体的有机碳密度约为37 884 t/km2；当沼泽地退化为草地或围垦为耕地后，土壤中有机碳的损失率高达66.6%~70.2%；1986—2006年研究区表层土壤（0~0.2 m）有机碳储量下降了约21%，而扎龙沼泽湿地区表层土壤有机碳储量则增加了近7%。

Abstract:

On the basis of data obtained from National Multipurpose Regional Geochemical Survey (NMPRGS) and National Soil Survey in Zhalong wetland and its surrounding areas of Heilongjiang Province, we studied the change of soil carbon storage in  the last twenty years, by estimating soil total carbon density(STCD), soil organic carbon density(SOCD) and soil carbon storage of different land uses. The results indicated that: (1)SOCD (0100 cm) is about 37884 t/km2 in Zhalong wetland; (2)the loss of soil organic carbon was as high as 66.7%70.2%, when wetland degraded to grass land or crop land; (3) from 1986 to 2006, surface soil (00.2 m) organic carbon storage decreased about 21% in the study area, while in Zhalong wetland, surface soil (00.2 m) organic carbon storage increased about 7%.

Key words: carbon density, carbon storage; , Zhalong wetland
