| 摘 要： | 本文在河北省土壤与地形体数据库基础上,计算了该省不同土壤组合的土壤有机碳和氮的密度,应用GIS技术分析了河北省土壤有机碳和氮密度的空间分布特征。结果表明:河北省土壤的平均有机碳密度为10.83kgm-3,平均氮密度为1070.96gm-3,C/N比为9.99;该省的土壤有机碳和氮密度的空间分布均呈现:不同类型土壤组合的有机碳和氮密度均随着纬度的增加而逐渐增加,而且其分布受气候、土壤特性、土地利用方式、植被特性以及人类干扰程度等的影响。 |

| Abstract: | In this paper, the organic carbon and nitrogen of different soil groups weve calculated by using the database of soil and terrain digital in Hebei province and the spatial distribution characters of soil organic carbon and nitrogen was recognized and analyzed by GIS. The results indicated that the average density of soil organic carbon and nitrogen in Hebei province was about 10.83 kg m~(-3) and 1 070.96 g m~(-3), respectively, and the C/N ratio was about 9.99. The average organic carbon and nitrogen of different soil groups increased with latitude and the spatial distribution was affected by climate, soil characters, land use, vegetation and human activities. |
