| 1 | Soil phosphorus bioavailability assessed by XANES and Hedley sequential fractionation technique in a glacier foreland chronosequence in Gongga Mountain, Southwestern China显示文摘The primary productivity of terrestrial ecosystems is influenced by soil phosphorus bioavailability, which depends largely on chemical fractions of phosphorus. The sequential fractionation technique developed by Hedley et al. or its subsequent modification is a well-known method to determine soil phosphorus forms. Hedley sequential fractionation technique separates the phosphorus into fractions based on their different chemical solubilities in extractants with certain chemical properties. Recently, synchrotron-based X-ray absorption near edge structure(XANES) spectroscopy has been employed to measure soil phosphorus species directly and non-invasively. The XANES method provides information concerning local structure and chemical information of target elements at a molecular level. Thus, it can distinguish phosphorus fractions bound by metal oxides or hydroxides(such as Fe, Al, and Ca). In this present work, the phosphorus speciation of topsoil along a glacial foreland chronosequence in Gongga Mountain is determined using these two methods. The changes in soil phosphorus bioavailability along the 120-year-old chronosequence are assessed based on comparisons of the results obtained by these two methods. The results indicate that Hedley sequential fractionation technique shows a greater ability to determine soil bioavailable phosphorus(Resin-P and NaCHO3-P), while XANES is effective in distinguishing phosphorus bound by metal compounds. In the chronosequence, Ca- and Al-bound phosphorus were derived mainly from primary minerals, whose phosphorus contents decreased within 120 years of moraine weathering and soil development. The content of soil bioavailable phosphorus increased rapidly after 30 years since deglaciation. The increasing phosphorus bioavailability promoted the colonizing and primary succession vegetation. | WU YanHong Jrg PRIETZEL ZHOU Jun BING HaiJian LUO Ji YU Dong SUN ShouQin LIANG JianHong SUN HongYang | 2014 | Science China Earth Sciences2014，57，8： | 6 |
| 2 | 两种形态分析方法对冰川退缩时间序列土壤中磷的生物有效性评价显示文摘土壤磷的生物有效性是陆地生态系统安全和初始生产力的重要影响因素.土壤中磷的生物有效性由其形态组成决定.常用的磷形态分类方法是Hedley提出的连续提取法,即通过不同化学强度的提取剂对土壤样品进行分步提取,各级提取剂提取出的磷被定义为不同形态的磷.近年来又推出了X射线吸收近边结构法(XANES),利用在分子水平上给出目标元素周围的局部结构和化学信息的优势,能区分出与Fe,Al和Ca等金属结合的磷的形态.本文利用改进的Hedley连续提取法和XANES方法对贡嘎山海螺沟冰川退缩迹地上土壤中磷的形态进行了分析,在比较两种方法优缺点的基础上,获得了海螺沟冰川退缩120年序列上土壤磷的生物有效性的变化.结果表明:Hedley连续提取法对即时生物可利用磷能有准确的判识(Resin-P和NaCHO3-P),而XANES方法对金属结合态的磷有很好的判识.海螺沟冰川退缩时间序列土壤中钙铝结合态的磷主要为原生矿物磷,随成土作用增强而减少.即时生物可利用磷从30年后迅速增加,促使了植被形成和演替. | 吴艳宏 Jorg PRIETZEL 周俊 邴海健 罗辑 余东 孙守琴 梁建宏 孙宏洋 | 2014 | 中国科学:地球科学2014，44，9： | 6 |
