| 摘 要： | 为了解城市土壤的肥力质量,服务于城市土壤健康管理。以京北城区环线公路绿化带附近的土壤为对象,研究了表层0~10 cm土壤的颗粒组成和养分指标特征。研究结果表明,土壤颗粒组成以砂粒为主,其含量高达71.74%,黏粒含量仅为4.04%,土壤质地主要为砂土及壤质砂土、砂质壤土。土壤pH值在8.01~8.97范围内,属微碱性到强碱性土壤;土壤有机质平均含量为19.81 g.kg-1,全N平均含量为0.81 g.kg-1,有效P平均含量为29.16 mg.kg-1,速效K平均含量高达252.22 mg.kg-1;土壤养分在不同区域的变化程度不同,变异系数由大到小为有效P>速效K>NH4+>NO3->全N>全P>全K;不同环路区域的土壤养分水平有明显差异,其中北二环路区域除全K和速效K外,其他养分含量均达到最大值,土壤养分总体表现为由市中心向外辐射呈逐渐降低的趋势;草地土壤中的全N、有效P及全K含量显著高于空地土壤。

| Abstract: | In order to understand the urban soil fertility quality and to serve soil health management,soil particle and nutrient contents in 0-10 cm layer near the different ring road greenbelts located Northern Beijing were analyzed.The results showed that sand content was as high as 71.74 %,while clay content was only 4.05 %,the soil texture types mainly belong to sand,loamy sand and sandy loam;soil pH values were from 8.01 to 8.97 and belonged to slightly alkaline or alkaline soil.The average contraents of soil or... |
