武汉北港生态农业基地微量元素分布特征

THE STUDY OF ENVIRONMENTAL GEOCHEMISTRY OF ECOLOGICAL AGRICULTURE IN BEIGANG, WUHAN

本文研究生态农业能量流、物质流良性循环过程中Cu等6个微量元素的环境地球化学循环,查明土壤、灌溉污水、淤泥及植物等各类介质中微量元素含量分布特征及其存在形式,探索生态农业—环境地球化学研究相互结合的途径,指出了生态农业建设中微量元素迁移循环规律研究的意义。

The paper concerns the environmental geochemical cycles of six trace elements (Cu, Pb, Zn, Mn, Co, Ni) in the benefical cycle of energy and mass flux of ecological agriculture. The distribution and mode of occurence of these elements in soils, irrigation sewage, mud and plants are surveyed, and the research way of the ecological agriculture combined with environmental geochemistry is explored. The significance of the knowledge about the migration of trace elements in construction of ecological agriculture is stressed.
