Abstract: Ecological rucksack fully reveals from the input end the impact of product manufacturing process on the natural resource consumption and the ecological environment, and is one of the main indicators that must be measured, monitored and controlled for the solution of ecological environment problems from the source. With Donganshan Iron Open-Pit Mine as the investigation object, detailed calculation and analysis are made of its ecological rucksack from 1995 to 2005 and suggestions are also made on alleviating the ecological rucksack of the mine. The research achievement will be of great practical significance to the quantitative research on the ecological pressure due to mineral resource exploitation, the calculation of the ecological rucksack of iron and steel products and the calculation of the indirect input related to the imported China steel products by other countries.
