| Abstract: | The paper reviewed the functioning mechanism of ecologic geochemical hazards and introduced the basic thought of ecologic 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 geochemical early-warning and forecasting were put forward. |
