再生水灌溉对绿地土壤的影响研究进展

Research Process on Influence of Reclaimed Water Irrigation on Green Space Soil

通过查阅再生水灌溉绿地的相关研究文献,总结了再生水灌溉对绿地土壤的影响及其研究的最新进展。长期用再生水灌溉会使绿地土壤的肥力、盐分及重金属含量增加,并且会发生盐碱化现象,使土壤板结,渗透率下降,对植物生长造成不利影响。归纳分析了避免和消除这些不利影响的方法,在此基础上,总结提出了再生水灌溉绿地需进一步研究的问题。

It was discussed that the influence of reclaimed water irrigation on the soil of green space and latest research development progress through the relevant literature of reclaimed water irrigation.Soil fertility,salt and heavy metal content would be increased with reclaimed water irrigation for a long term.And soil hardening,permeability decreased and other negative impact on plant growth would occur because of the soil salinization phenomena.It is systemic analyzed and discussed how to avoid and eliminate these adverse effects.The problems of further research is presented base on those ways above.
