摘　　要：为研究上海外环绿带土壤质量,推进植被功能提升,在上海外环绿带布设了94个点,从土壤肥力质量、环境质量和健康质量3个方面,综合评价了上海外环绿带土壤质量。结果表明:(1)上海外环绿带土壤肥力质量堪忧,土壤肥力质量指标主要分布在影响植被生长的四级、五级和六级,78.7%的采样点土壤肥力质量分布在“贫瘠”等级;(2)土壤环境质量较好,土壤环境质量指标主要分布在无污染的一级,88.3%的采样点土壤环境质量等级为“清洁”;(3)土壤健康质量不容乐观,72.6%的采样点土壤健康质量分布在“很低”等级;(4)容重、总孔隙度、非毛管孔隙度、p H、有机质、碱解氮和有效磷是影响土壤肥力质量的主要因素,土壤肥力质量也显著影响着土壤健康质量。上海外环绿带应通过施用有机无机材料,全面提升土壤质量。To investigate soil quality of the outer green belt of Shanghai and promote the improvement of vegetation function,in this study,94 points were set up in the outer green belt of Shanghai,and the comprehensive evaluations of soil quality were conducted in terms of soil fertility quality,environmental quality,and health quality.The results showed that:1)soil fertility quality was worrying,soil fertility quality indicators were mainly distributed in the fourth,fifth and sixth levels that hinder vegetation growth,78.7%of the sampling sites were in the poor level of soil fertility quality;2)soil environmental quality was good,with soil environmental quality indicators were mainly distributed in the first level without pollution.The proportion of soil environmental quality classified as clean was 88.3%;3)soil health quality was not optimistic,and mainly distributed in the very low level(accounting for 72.6%).4)soil bulk density,total porosity,non-capillary porosity,pH,organic matter,alkaline nitrogen,and available phosphorus were the main factors affecting soil fertility quality,which also significantly affected soil health quality.To comprehensively improve soil quality of green belt of Shanghai,organic and inorganic materials should be applied combinedly.
