摘　　要：以西安市区林业土壤为研究对象,系统采集了0--20cm土壤样本,研究了土壤容重和速效养分现状。分析结果表明,道路绿地土壤容重最大,显著高于其他三种绿地,公园绿地、街头绿地、附属绿地之间差异不显著;公园绿地速效氮含量最高,道路绿地含量最低;其中附属绿地速效磷含量最高为38.08 mg.kg-1,道路绿地速效磷含量最低为13.27mg.kg-1。The particle takes forest soil in Xi＇an area as the research object,the system collects soil samples with 0-20 cm and analyzes soil bulk density and available nutrient status. The results show that the largest road greenbelt soil bulk density was significantly higher than the other three green and the difference between green parks,green street and attached green is not significant. Green parks available nitrogen content of the highest and lowest road green content wherein the accessory greenbelt available phosphorus reaches 38. 08 mg / kg- 1and the lowest road green space available phosphorus content was 13. 27 mg / kg.
