Abstract: There are some availalle nourishment in city sludge for plants to absorb,and some heavy metal elements toxic to plants.With the intention of investigation of the effect of various elements in city sludge under different use leueles on the Bromus inermis,we spread the sludge the waste mud in seuage treatmen plant of Qilihe district of Lanzhou,Gansu Province on Bromus inermis pasture from 1996 to 1998.The results showed that the city sludge can be considered a kind of biolgical resounes available for the pasture for the reason that the various metal elements contained in the city sludge neither accumulated in the Bromus inermis,and nor polluted soil by way of moving to the soil beyond 20 cm depth.

Key words: City sludge, Metal element, Bromus inermis, Soil

摘要： 城市污泥中含有较多或可供植物吸收利用的养分,也含有一些危害植物的重金属元素。为了探讨污泥对无芒雀麦吸收利用的影响,将七里河区污水处理厂生活污泥施于无芒雀麦人工草地。3年来对无芒雀麦和土壤进行多项监测,结果表明,各种重金属元素未在无芒雀麦体内积累,也没有向20cm以下的土壤中迁移,对土壤没有污染,是一种可在草地中应用的肥源。
