穆珠朗玛峰地区土壤中稀土元素的含量和分布

本文论述了珠穆朗玛峯地区土壤中稀土元素的含量,以及它们在土壤中的分布模式,并发现土壤中稀土元素的含量水平在很大程度上受土壤母质的制约。     

稀土元素的环境生物地球化学循环研究现状

本文对稀土元素在农用领域的研究进展及其在土壤、水体和植物中的分布、迁移与归宿特征作一系统总结,并对该领域的发展趋势进行了简要的说明。随着自然和人为因素造成的环境中稀土元素的增加,进而产生对生态环境和人类健康的影响,已引起全社会的关注。土壤中稀土元素的存在形态是生态环境效应和生物利用性的的重要参量。目前的实验结果在不同地区和不同土壤剖面中稀土元素的存在形态不尽相同,推测主要与其母质的组成及所处气候等环境条件相关。最近国际上已对稀土元素的水化学过程进行了较广泛的研究,水体中稀土分布受水体的化学参量（如pH, 有机质等）和水化学过程影响,含量高低与人为活动有直接关系。植物中稀土元素的分布通常与土壤中稀土的含量多少相一致,在外施稀土的条件下,在施用后短期内稀土在各器官分布与施用部位密切相关,目前对植物体内稀土元素存在位置和赋存状态的实验结果差别明显,对植物中稀土元素的超富集机理不清等问题尚待进一步探究。     

岩溶盆地红土风化剖面的元素地球化学研究

选取云南石林红土剖面作为研究对象,探讨在岩溶盆地这一独特地貌单元中主量、稀土元素的地球化学特征。研究表明：① 云南石林土壤中主量和稀土元素的组成具有较好的一致性;② 通过对化学蚀变指数（CIA）与Na/K比值关系图以及A-CN-K（Al₂O₃-CaO*+Na₂O-K₂O）三角图分析发现：石林地区2个剖面均经历了温暖湿润环境下的强烈化学风化作用;石林地区土壤中稀土元素含量较高,其稀土元素球粒陨石标准化分布模式表现出高度相似性,且继承了基岩的特征,两者均表现为Eu处负异常,但剖面CK在Ce处表现为负异常,而剖面KP在Ce处无明显变化;③ 2个剖面元素组成及含量变化基本保持一致,表明此地土壤受外来物质影响程度较小,2个剖面的元素地球化学特征与基岩存在一定相似性。     

河南省稀土不同含量区粮油作物品质的研究

通过对稀土不同含量区粮油作物品质的研究,得知稀土元素能促进粮油作物籽粒中蛋白质和Ｐ２Ｏ５的积累,且具有提高酸性土壤作物吸收多种元素的能力。从试验数据中看出、富含稀土的酸性土壤上生长的粮食中营养元素的含量与稀土累积呈正相关。     

吉林省西部草地土壤的化学元素含量及其特征研究

对吉林省西部草地土壤化学元素含量研究表明，吉林省西部草地土壤中富钾少磷；钙、镁含量丰富；硼、铜、铁、锰含量在剖面上表现为向下增加；土壤中氮、磷、钾、钙、铜含量随草地退化程度的加深而减少；土壤中硅、钠含量丰富，显示出较强的沙化、盐碱化趋势，其含量随草地退化程度的加深而增加，钴含量随草地退化程度加深而降低；钡含量随草地退化程度的加深有增加的趋势；而稀土元素总量低于土壤背景值，并随着草地退化程度的加深其含量有减少的趋势。     

汉水水系水环境中稀土元素的分布特征

系统探讨了汉水水系水相（原水、滤水、悬浮物）、沉积物相中8个稀土元素的含量水平、丰度模式、悬浮物含量对水中元素含量的影响及沉积物粒度对元素的富集与分散作用等，结果表明：Eu、Lu主要以溶解态存在于水相中，而Sm主要存在于悬浮物中；汉水水中稀土元素的含量基本在世界淡水的范围内；湖库悬浮物中稀土元素含量均低于江河悬浮物，悬浮物和细粒沉积物中稀土元素含量相近，序列也基本一致；粒度对汉水沉积物中稀土元素含量的影响不明显；地表径流对水中悬浮物含量和悬浮物中稀土元素含量均有一定影响，稀土元素在汉水悬浮物、沉积物中均有一定程度的富集现象；汉水各相中均以轻稀土为主，重稀土含量较少。     

表生作用下稀土元素地球化学特征——以海南岛北部玄武岩分布区为例

对海南岛北部玄武岩区岩石-土壤-植物-地下水系统中稀土元素迁移和分布模式的研究表明，随土壤的发育，REE出现分异，LREE逐渐富集；Ce由玄武岩中的负异常向土壤中正异常演化。地下水中REE的含量和分布模式主要受岩石风化和成土作用影响。植物虽对REE具有选择吸收作用，但REE的生物地球化学循环不活跃。     

北极楚科奇海近代沉积物稀土元素地球化学特征初探

于 1 999年夏季我国首次北极科学考察期间在楚科奇海采集了三个沉积物岩芯 ,并采用中子活化法 (INAA)测定了沉积物样品中稀土元素的含量。结果表明 ,其含量与东海大陆架细粒沉积物的稀土元素含量十分接近。稀土元素的含量沿沉积物岩心的垂直分布呈现出随深度轻微增大的趋势。页岩标准化的稀土元素配分模式相对平缓 ,Ce有轻度负异常 ,表明沉积物稀土元素除了陆源物质以外 ,也存在生物沉积作用的来源。稀土元素与指示陆源的元素Al具有良好的正相关关系 ,相对于地壳丰度所计算的富集因子接近于 1 ,进一步说明楚科奇海沉积物中的稀土元素以陆源物质输入为主 ,通过江河携带入海 ,最后随碎屑物质、悬浮物而沉积下来 ,并保持一种稳定的沉积状态。     

用偶氮胂M光度法测定卤水(盐)中稀土元素总量工作报告

盐湖卤水组成复杂,除含有大量碱金属、碱土金属外,尚有多种微量元素存在,其中稀土元素就是一例。但由于多数盐湖卤水介于中性或微碱性,稀土元素和某些重金属均已沉积,因此盐湖卤水中稀土元素含量甚微。我室现有的三元络合物萃取光度法测定稀土总量的方法虽然灵敏度和选择性均佳,但不完全适应卤水中低含量稀土元素的测定。基于这点,在盐湖卤水中测定微量稀土元素需要一个高灵敏度的方法,同时对大量共存元素必须进行分离。     

长江武汉江段水体中稀土元素的含量和形态

本文采用中子活化分析技术同步研究了稀土元素在长江武汉江段水－悬浮物－沉积物中的地理含量分布及其赋存形态。结果表明，稀土元素在河水中溶解态含量极微，而悬浮态含量较高变幅较大。沉积物与悬浮物中稀土元素含量相近，其含量高低与粒级大小呈负相关，与矿物组成密切相关；稀土元素分布模式均为轻稀土富集、Ｅｕ亏损型。各元素赋存形态均以结晶态为主，各形态所占比例的排序为结晶态≥有机硫化物态＞铁锰氧化物态＞碳酸盐态≥可交换态。各稀土元素相对比较，５种形态的分配比例有一定差异，中稀土Ｅｕ、Ｓｍ、Ｔｂ较轻，重稀土的结晶态所占比例低，而其它形态则相反。

Deserts and Aeolian Desertification in China: Book review and some thoughts

Desertification is a global phenomenon that affects about two billion people. It occurs in arid zones where the annual precipitation is below 400 mm, partic- ularly in the marginal areas of the world＇s largest deserts. It is a result of water and wind erosion, over- grazing, global warm-ing, improper soil cultivation, and increased pressure ot population growth, and it causes degradation of soil and natural and agricultural vegetation. The direct result is less food for people and livestock, which influences pop- ulation and animal husbandry fluctuations. Despite ef- forts to combat and reduce desertification, the affected areas are annually increasing.
