Abstract:

利用多目标区域地球化学调查的实测数据,估算了吉林中西部地区表层土壤的有机碳密度和储量。结果表明,在不同深度的分布层次上,表层(0~0.2m)土壤对有机碳的积累较弱,SOC储量占到全层(0~1.8m)储量的23.8%,中上层(0~1.0m)储量则占到全层储量的95.7%。从土壤类型看,表层SOC密度较高的有暗棕壤(6363.8±3900.5t/km2)、栗钙土(5001.9±1313.2t/km2)、白浆土(4629.8±1921.5t/km2)和水稻土(4193.6±1509.6t/km2)等;储量较丰富的是黑钙土(66.969±25.460Tg)、暗棕壤(65.929±40.410Tg)、黑土(46.837±14.553Tg)和新积土(43.368±20.910Tg)等。就土地利用方式而言,水田(4150.2±1813.8t/km2)和林业用地(4133.4±3450.2t/km2)的表层SOC密度最高;旱田(140.186±52.156Tg)和林业用地(104.442±87.180Tg)的表层SOC储量最高,二者共占到表层SOC总储量的75.6%。在空间分布上,吉林中西部地区SOC密度西北低、东南高,大致呈现出由西北向东南逐渐增大的趋势。较低碳密度带包括白城和松原的大部分地区、四平地区的西部,较高碳密度带主要包括吉林、辽源、长春地区,这3个地区面积为全区的1/3,但集中了全区表层SOC总量的一半,其中吉林地区SOC平均密度最高,达到6305.8±4018.8t/km2;此外白城西北部地区碳密度也比较高。与第二次土壤普查数据进行了对比研究,结果发现表层SOC平均含量从1.45±0.80%减为1.24±0.82%,平均密度从3834.7±1087.5t/km2降为3436.7±2249.7t/km2,储量则由366.167±103.840Tg减少至328.165±150.124Tg,净减少38.002Tg,有机碳以0.199tC/ha·a的年变化速率由土壤排放进入大气中,其中以沼泽土、白浆土和暗棕壤的碳损失速率较快,吉林中西部地区表层土壤在区域碳循环中发挥着碳源的作用。
