| 中文摘要: |
| 为探讨利用中水进行绿地浇灌的可行性，采集市政中水浇灌区绿地及自来水对照区不同深度
土壤样品，对其微生物数量、重金属含量和Cl- 含量进行对比分析。结果表明，中水浇灌区土壤微生物的数
量显著高于自来水对照区，同时，土壤深度对土壤微生物数量影响显著，以30～40 cm 土层的土壤微生物数
量最低；中水和自来水灌溉下土壤的重金属含量差异不显著，但不同重金属含量在不同的土壤深度分布差
异显著，全Zn、全Pb 和全Cd 含量超出广东省土壤背景值，但均未达到危害人体健康程度；中水处理的土
壤Cl- 含量显著高于自来水对照，但在适宜的土壤氯含量范围内。 |

| In order to explore the feasibility of using the reclaimed water to irrigate green landscapes，the soil
samples of different depths were collected in reclaimed water irrigated areas and tap water areas for the microbial
quantity，heavy metal content and chloride ion content were compared and analyzed. The results showed that the
number of soil microbes in the reclaimed area was significantly higher than that in the tap water area. The soil depth
had a significant effect on the amount of soil microbes，while the number of microbes in the depth of 30-40 cm was
the lowest. The difference of heavy metal content between reclaimed water irrigated areas and tap water areas was
not significant. The contents of heavy metals in different depths of soils were significant，and total Zn，total Pb and
total Cd exceeded the background values of soils in Guangdong Province，but all of them did not reach the level of
endangering human health. The chloride ion content of irrigating reclaimed water soil was significantly higher than tap
water irrigated area，however，in the appropriate range of soil chlorine content. |
