中文摘要	文章采用7步连续浸提法对采集于巴丹吉林沙漠北部沙样中磷的各种存在形态进行了分析测定,并对沙样进行了分级形态研究。测定结果表明:在巴丹吉林沙漠北部沙样中总磷(TP)的含量范围为164.28～342.85mug/g,平均含量为275.20mug/g,其主要成分为无机磷(IP),平均含量为264.24mug/g,占TP含量的96.02%;而有机磷(Or-P)平均含量为10.96mug/g,平均占TP的3.98%。在所有不同粒径的沙样中,自生钙结合磷(Ca-P)含量最高,平均为217.17mug/g,占TP的78.91%,其次是原生碎屑磷(De-P),平均含量43.36mug/g,占TP的15.76%,二者占TP的绝大部分;其他各形态磷含量的高低顺序依次为:有机磷(Or-P)、铝结合磷(Al-P)、铁结合态磷(Fe-P)、可交换磷(Ex-P)、闭蓄态磷(Obs-P)。在所取沙漠颗粒物样品中Ca-P、De-P和Ex-P的含量均随沙样粒径的减小而增大;Or-PFe-P的含量随粒径的减小而减小;Obs-P、Al-P、的含量随粒径的变化无特定规律;总磷(TP)含量随沙样粒径的减小而增大。
英文摘要	Various phosphorus species in sand grains with different sizes from Badanjilin Desert located at upper stream banks of Yellow River in western region of Inner Mongolia were studied with seven-step sequential extraction method. Results showed that concentration of total phosphorus(TP)ranged from 164.28 to 342.85mug/g,with average of 275.20mug/g. Average IP content was 264.24mug/g,which was 96.02%in TP.Ca-P was found to be the major phosphorus form in TP with different particle sizes,followed by De-P and Or-P.In the sand samples with different particle sizes,contents of Ca-P, De-P,Ex-P and TP increased with sample particle size decreasing respectively,but Or-P and Fe-P were contrary.No remarkable dependency relationship between content and sand particle size for Al-P and Obs-P species are found.
