摘要: 硒是环境中重要的生命元素,它在环境中含量水平的高低直接影响着人及动植物的健康安全。结合国内外资料及最新的研究进展,阐述了环境中硒的生物地球球化学循环,包括环境中硒的生物地球化学循环特征,土壤中硒的含量分布、形态及有效性,大气和水环境中硒的形态分布,植物体中的硒及其对硒的吸收关系;讨论了低硒高硒环境中硒营养水平的调节及环境分异的成因,诸如母质类型、气候特征、风化淋失、气体挥发、土壤质地和地力耗竭等方面;并提出了环境中硒研究的前沿及今后关注的热点问题,以促进今后环境中硒的研究。

Abstract: Selenium(Se) is an important biosis element,and its content in environment directly affects the health and safety of human beings,animals and plants.Based on the latest research advances at home and abroad,this paper set forth the biogeochemical cycling of Se in environment,including the characteristics of Se biogeochemical cycling,the concentration distribution,forms and availability of soil Se,the species distribution of Se in atmosphere and water,and the Se in plant and its absorption.The adjustment of low and high Se in environment and its differentiation cause was discussed,such as parent material type,climate character,weathering and leaching,gaseous volatilization,soil texture,and soil fertility exhaustion.Related hotspot problems and research frontiers of Se in environment were reviewed.

Key words: Genotype of Frankia, Gaoligong Mountains, IGS PCR-RFLP
