河北平原土壤有机碳含量的变化
Changes of Soil Organic Carbon Content in Hebei plain
摘要
Abstract
According to the second general soil survey data in 1979 and the multi-target geochemical survey in 2004 and other information. Grid cell are used to calculate the organic carbon storage of different types of soil in the Hebei Plain, including 0~0. 2m and 0~l. 8m in the year 1979 and 2004. The result shows that during 25 years the soil organic carbon content of the Hebei Plain keeps growing. The average organic carbon of the top and deep soil in 2004 has respectively increased by 24. 25% and 31. 39% than which in 1979. The factors, which affect the carbon storage capacity of soil, are water content, soil parent material, soil texture, etc. Such types of soil as rice soil, bog soil, lime concretion black soil etc. With higher content of water and clay has the stronger ability of soil carbon storage. Otherwise ifs weaker when the types of soil are the wind sand soil, new product soil and likewise with lower water and clay content. The destruction of vegetation and the loss of soil water will decrease the soil organic carbon storage of the types of soils with high water content. In this study, ifs showed that the average organic carbon storage of most soil types increased except the surface of the brown soil, bog soil, seashore saline soil and deep brown soil and bog soil, whose storage decreased.关键词
