摘　　要：中国土壤碳库储量低,平均碳容量仅为世界水平的一半,因而潜力也就特别巨大,合理开发利用土壤碳库对固碳减排有重大意义。开发利用土壤碳库在土壤选择上应着重农田土壤与草原土壤,地域选择上应重视东北黑土农区与内蒙、青海等地的沙化草原区,而在技术选择上,应重视开发农业废弃物的有机肥利用,把农业废弃物利用率60%～70%、有机肥施用比例50%作为努力的目标。Soil carbon stock is low in China, only half of the averaged level in the world, the potentiality thus is huge as well. Scientific exploitation of soil carbon pool is meaningful in the C sequestration and decrease of CO2 emission. Based on soil types, farmland and pasture should be chosen firstly ; Considering the tillage areas, more attention should be paid to the agriculture area in black soil in the Northeast China, and the desertified grassland in Inner Mongolia and Qinghai province; When choosing measurements, the use of organic manure made of waste of agriculture should be considered. An ultimate object is to achieving a use of 60% -70% of agricultural waste and 50% of the total nutrient inputs from organic fertilizer.
