摘　　要：回顾了生态地球化学危害效应的作用机理,提出了区域地球化学调查-地球化学环境监测-机理研究相结合的生态地球化学预测预警基本思路。根据当前中国多目标区域地球化学调查和生态地球化学评价工作的现状,举例说明了土壤重金属元素累积、土壤环境变化、生态效应机理的若干研究方法,提出了预测预警成果体现的若干建议。The paper reviewed the functioning mechanism of ecologic geochemical hazards and introduced the basic thought of eco- logic geochemical early-warning and forecasting by integrating with regional geochemical survey, environmental geochemistry monitoring and mechanism research. Based on the current situation of the multi-purpose regional geochemical survey and ecological geochemical assessment in China, research methodology was illustrated by some examples in terms of heavy metal accumulation in soil, soil environmental variation and ecological effect mechanism. Also, several suggestions on outcome presentation of ecological geochenfical early-warning and forecasting were put forward.
