| 摘 要： | 为促进生态化城市建设和保证区域城市的可持续发展，采集西安市浐灞生态区主要地段0～20 cm层次土壤，分别测定土壤pH值、有机质、碱解氮、速效磷、速效钾等指标，并采用改进的内梅罗指数对各地段的土壤肥力状况进行综合评价。结果表明:西安市浐灞生态区绿地人为扰动严重，其中:国家湿地公园的土壤肥力属于贫瘠水平；浐河西路、大道(浐灞大道、广运潭大道、欧亚大道)、北辰路、灞河西路、灞柳路、雁鸣湖2号湖湖心岛、雁鸣湖垃圾山、雁鸣湖5号湖预留湿地地段的土壤肥力属于一般水平；雁鸣湖3号湖西岸土壤肥力属于肥沃水平；土壤有机质是浐灞生态区土壤肥力的限制因子。针对上述分析结果，本研究提出了相应的建议和改良措施。

| Abstract: | Information about the soil fertility of greenbelts is needed to promote rapid and sustainable urban development.Soil samples (0--20 cm depth) were collected from main areas of the Chanba ecological zone of Xi’an City,northwestern China.The samples were analyzed to determine soil pH,organic matter content,alkali-hydrolysable N content,available phosphorus content,and available potassium content.The results were evaluated using the modified Nemerow Index.There was significant human disturbance in the ecological zone.Soil fertility was low in the national wetland park,intermediate in regions near to Chanhe West Road,Avenue(Chanba Avenue,Guangyuntan Avenue,Ouya Avenue),Beichen Road,Bahe West Road,Baliu Road,Fort Island of Yanming Lake No.2,garbage mountain of Yanming Lake,reserve wetland of Yanming Lake No.5,and high in the No.3 Yanming Lake region.Soil organic matter content was the limiting factor of soil fertility in the Chanba ecological zone.Some measures are suggested for scientifically managing these soils. |
