摘　　要：结合北京市污泥堆肥土地利用现状．研究了污泥堆肥对土壤环境及高羊茅（Festuca arundinace。）的影响。旨在为北京市污泥堆肥用于高羊茅园林生产提供理论依据，促进资源再利用。研究结果表明．施用污泥堆肥增加了高羊茅栽植小区土壤养分含量，特别是土壤中有机质含量增加明显，与空白对照相比增加了43．9％～73．2％，对土壤养分状况具有一定的改良效果；施用污泥堆肥后，高羊茅栽植小区土壤中重金属含量虽有不同程度的增加。但均远低于相关标准限值．且土壤重金属污染综合指数小于土壤安全限值0．7．表明种植小区土壤未受到重金属污染：施用污泥堆肥对高羊茅生长具有一定的促进作用．与空白对照相比．高羊茅总生物量增长率为16．7％～50．0％。综合分析试验结果，确定污泥堆肥用于高羊茅的适宜施用量为2kg／m^2。Based on land use situation of sewage sludge in Beijing, the effect of using sewage sludge compost on soil and grass growth was studied. The purpose of this study was to supply the theoretical basis for grassing with sewage sludge compost which can promote sludge recycling. The results showed that nutrients especially organic material concentration in soil increased obviously after using sludge compost, which 43.9% ~73.2% higher than blank control. Heavy metal concentration also increased but be lower than relevant environmental standards. Comprehensive pollution index is lower than the safety value of 0.7, which indicated experimental soil not polluted by heavey metals. Sewage sludge compost can promote grass growing with the biomass increased 16.7%-50.0% than blank control. Based the results, 2 kg/m2 is advised to be more suitable sewage sludge compost amount on grassing.
