| 摘 要： | 研究开封城市土壤有机碳,发现不同功能区类型间及城区与郊区间的有机碳特性存在差异:土壤表层有机碳含量为工业区>休闲区>交通区>文教区>行政/居民区;表层有机碳密度为休闲区>工业区>交通区>文教>行政/居民区;土壤剖面有机碳密度为文教区>交通区>工业区>休闲区>行政/居民区.城市土壤表层有机碳密度和剖面有机碳密度均沿城郊剖面线呈下降式梯度变化,城区分别是郊区的2.53和1.56倍.城市土壤有机碳积累主要在地表之下0～30 cm范围内. |
| 关 键 词： | 开封市 城市土壤 有机碳含量 有机碳密度 |

| Abstract: | Urban soil,a special soil type,forming along with the development of city,has unique properties of soil organic carbon.On the basis of field investigation and laboratory analysis,the soil organic carbon(SOC)of Kaifeng City,Henan Province was studied,and the results showed that the characteristics of SOC were different not only among function districts in urban area,but also between urban area and suburb.The contents of SOC in topsoil followed the order of industrial district> recreational district > traffic... |
| Keywords: | Kaifeng urban soil content of soil organic carbon density of soil organic carbon |
