The research is about the reuse of urban sewage for virescence irrigation, and the influence of sewage irrigation on eco-environment such as soil, plant, etc. is studied. Under the condition of field sewage irrigation, the transport and transformation and accumulation mechanism of heavy metals, nutrients and organic pollutants as vaporizable hydroxybenzene etc. in the soil-plant system are analyzed. The heavy metal pollution is evaluated by the comprehensive pollution index. The spatial variability of heavy metals in sewage irrigation area is further understood. The spatial variability of heavy metals and physical and chemical properties of soil are reflected in a more straight way by the theory model of variance function curve based on the geographical information system.

在城市污水回用于绿化灌溉对土壤、植物等生态环境的影响研究中分析了大田条件下污灌对土壤-植物体系中重金属、养分及挥发酚等有机污染物迁移转化及富集机理，对重金属污染进行了综合污染指数评价，进一步了解了污灌区重金属分布的空间异质性，基于地理信息系统提出了变异函数曲线的理论模型，更直观地反映出了重金属元素与土壤理化参数的空间变异特征。

The results showed that : three species all can resistant to drought ,wind-drift sand and endure to sterile soil, and with fine adaptability to local condition that there are irrigation in growth phase and no irrigation in post-vegetative phase in 2002 and there are no irrigation in growing period and irrigation in after bearing phase in 2003. Among the three species ,Agropyron cristatum× A.desertorum cv.
