林线附近主要植被类型下土壤非生长季磷素形态

, 2010
采用Hedley磷素分级方法,比较研究了岷江上游林线附近不同植被类型(高寒灌丛草甸、雪山杜鹃灌丛和岷江冷杉林)非生长季0—20cm土壤无机磷和有机磷形态。结果表明,研究区内土壤总磷平均含量(857.32mg•kg-1)较高,但活性磷含量仅占总磷的10%左右。生物态磷含量占总磷含量的60%以上,表明土壤磷素受生物作用影响较大。3种植被类型下土壤无机磷主要以D.HCl-Pi(稀盐酸提取无机磷)和C.HCl-Pi(浓盐酸提取无机磷)形态存在,活性无机磷和NaOH-Pi含量较少。高寒灌丛草甸土壤D.HCl ...

孟良崮小流域径流与磷素传输动态关系

Shuitu Baochi Xuebao
目的 为探讨不同降雨类型下径流-磷素流失滞后关系特征。方法 以北方土石山区孟良崮小流域为研究对象，利用2010—2012年的32场降雨实测数据，通过C-Q(浓度-流量)环路和Pearson相关分析方法进行分析。结果 1) 暴雨条件下，土壤饱和后释放大量磷素使磷素浓度峰值晚于径流峰值；大雨条件下，溶解性磷素从近源释放，颗粒态磷素从远源迁移到径流中；中雨条件下，DIP(溶解性无机磷)、PP(颗粒性磷)和TP(总磷)输移主要受地表径流影响，DP(溶解性总磷)输移受到土壤和沉积物影响；小雨条件下 ...
