This study was conducted in Taiyuan sewage irrigation area from 1997 to 2000.The research process included field investigation, sampling, lab test, model experiment and data analysis by geo-statistics method. The source, affecting factors, content condition, transference regularity, spatial distribution of heavy metal in sewage irrigation area were studied. The results showed that mercury, cadmium and lead contents of soil were higher than soil background value.

本文以在中国北方具有代表性的太原污水灌溉区为研究对象,污灌区位于山西省中部的太原盆地北端,总面积2.7万公顷,在研究区共布土样点49个,粮食作物样33个,水样点26个,大气样点6个,通过实地调查取样监测和室内模拟试验,采用地统计学和多元统计等方法,系统研究了污灌区土壤-作物系统中重金属Hg、Cd、Pb的来源、含量状况、累积影响因素、空间分布特征、迁移转化规律、重金属环境容量的区域分异与应用等内容。

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。

From the 'responses' made by Ji Guangmao, however, we can see nothing appropriate and academic except for all the insulting vituperation and bawdry on Zhong Hua and his family.
