【摘要】 以3种水源灌溉土壤并进行实验研究,对测定结果做模糊聚类分析,从而为我国水资源的回收利用提供科学依据.实验结果表明,再生水有效地提高了土壤肥力,而雨水相应的使土壤肥力大幅度降低.自来水与再生水大部分指标,随着土壤深度的加深而逐渐减弱,而雨水则正好相反.关于再生水和雨水的回收利用还有待于更深入的研究.更多还原

【Abstract】 In order to be an evidence for the reuse of water resources,investigated the fertility in soil which was irrigated by both of those two water resources and analysis it by fuzzy cluster.The results showed that the recycled water can effectively increase the fertility in soil,and the rainfall reduced the fertility of the soil.In company with the deepness of soil deepen,mostly indices of tap water and recycled water wear off,therefore rainwater diverse.The reuse of the treated water and rainfall should be investigated much more.更多还原
