摘　　要：为探明汾河公园东岸不同区域绿地土壤的肥力特征,为汾河公园及汾河段在建的其它公园土壤肥力管理提供借鉴,以临汾市汾河公园东岸绿地土壤为研究对象,对pH、有机质、速效养分几项指标进行比较研究。结果表明:汾河公园东岸土壤整体肥力较差,但表层土壤经过改良后肥力特征有所改善;各肥力指标在不同区域的分布特征有差异:pH和速效钾均形成显著性差异(P<0.05),有效氮近岸人行道和车行道没有显著性差异(P>0.05),但两者与绿化带间人行道有显著性差异(P<0.05),有机质和有效磷未形成显著性差异(P>0.05);不同区域绿地土壤综合肥力依次为近岸人行道>车行道>绿化带间人行道。In order to provide a basis for the soil fertility management in Linfen Fen river park and other newly constructed parks along the Fen river, green space soil on the east coast of Linfen Fen river park were taken as the study object, and the soil fertility characteristics was discussed based on the comparative study of seveal indicators including soil pH value, soil organic matter, AN, AP, AK. The results show thatthe soil fertility was low generally on the east coast of Linfen Fen river park. The contents were improved significantly in the top- soil, which was owing to some measures were applied; There were differences in the distribution characteristics of soil fertility indexes among different areas： the soil pH value and the content of available potassium（AK） had obvious differences （P〈0.05）. The content of available nitrogen （AN） didn＇t shown such obvious differences between the sidewalk near the shore and roadway （P〉0.05）, but were significantly higher than it on the sidewalks between the greenbelt （P〈0.05） ; the soil organic matter （SOM） and the content of available phosphorus （AP） had no significant differences （P〉0.05）; the comprehensive soil fertility of green space among different areas was as follows： the sidewalk near the shore〉roadway〉he sidewalks between the greenbelt.
