1污水灌溉对林地土壤中磷的数量与形态影响显示文摘为避免城市生活污水携带的N、P进入水体,新西兰罗托鲁阿市处理后的污水直接喷灌至Whakarewarewa森林,同时建立污水灌溉林地处理系统长期定位试验地,以评价林地生态系统对污水携带营养物质的同化能力。为了解长期污水灌溉对土壤中P的数量、形态、环境的影响,对该灌溉系统中的土壤进行了剖面采样分析。结果表明:土壤TP(全磷)、Olsen P、M3P(Mehlich-3 P)在所有灌溉区的表层土壤(0~10 cm)均有显著(p<0.05)增加,部分指标的显著增加达深层土壤。随灌溉进入土壤的P大多被保存在上层土壤(0~40 cm)中。土壤中各形态的磷所占比例因长期污水灌溉而改变,灌溉前占优势的NaOH Po(以NaOH浸提得到的有机磷)经长期灌溉后被NaOH Pi(以NaOH浸提得到的无机磷)所取代,上层土壤WSP(水溶性磷,Wa-ter-soluble P)变化明显。以Olsen P 60 mg kg-1和M3P 150 mg kg-1为环境临界值可预测土壤剖面中P的淋失危机,WSP可望成为适用更广的土壤P淋失环境危机预测指标。胡慧蓉 王海龙 Katie Beecroft Mark Kimberley 2012土壤学报2012,49,3:5
