摘 要:再生水灌溉是解决水资源短缺的有效途径,在北京市选取新河再生水灌区,对土壤质量情况进行研究分析。结果表明:再生水灌区土壤中重金属含量未对土壤产生不利影响;再生水灌溉对土壤碱性的危害性较低;再生水灌区土壤阴离子含量相比井灌区含量变化要稳定,对作物影响程度小;再生水灌溉可以提高土壤有机质含量,对土壤具有较好的保肥能力。Irrigation by using reclaimed water is an effective way to resolve the shortage of water resources. We studied the soil quality of Xin-He irrigation area in the eastern Beijing by selecting the representative area using reclaimed water. The results showed that the heavy metal concentration in the soil irrigated with reclaimed water has little negative effect on the soil, and have little alkaline harmfulness to the soil. The anionic concentration in the reclaimed water irrigation soil was more steady and less influence than that in the clean water irrigation soil. In addition, reclaimed water could improve the soil organic content and the ability of protecting fertilizer.
