Ecological Rucksacks Of Chinese Gold Mines In The Exploitation

The exploitation of the Chinese gold mine resources on the one hand provides important raw material for the our country industry, on the other hand, brings the impact to the ecosystem environment . At the beginning period of 1990s, the Ernstvon Weizsaecker of the German Wuppertal's graduate school puts forward the concept of the Ecological Rucksacks. The Ecological Rucksacks are that for acquiring the useful material or product the mankind put to use the material which do not enter into trade and product line of material directly, being called Hidden Flow in Material Flow Accounting (MFA). At present, the Ecological Rucksacks are synthetical quantitative index which the international want to tack as the token of this kind of impact. It visually gives expression that the material production flow consume the natural resources and impact the environment from the input range. It is one of the most important index and it must be measured, inspected and controlled when resolving the Ecological Rucksacks from the source. Meanwhile, the Ecological Rucksacks are also one of the most important index to measure the sustainable development. Because the main material of the mostly industrial product's constitute are metals and nonmetals, the study of mineral resources exploitation on the Ecosystem Rucksacks has important meaning.My thesis takes Chinese gold mine resources exploitation as the research object. From gross domestic product(GDP), compute the Ecological Rucksacks from 1990 to 2001, and study the social problem- metabolizable theory of the matter and ecology. Economy and culture determine the metabolize of the anthropic society. The social metabolize change the environment, and at last the society is also changed. The resources in the earth are limited, so the matter throughput which determines the scale of the metabolize is limited. The study results calculate the gold mine resources'Ecological Rucksacks of our country further, and they have the practical value on the other countries importing Chinese gold mine products corresponding to indirect input. The study results show exploring and machining gold mine resources impact the environment and point out the consists of the Ecological Rucksacks and offer the measurement in order to relieve the ecological environmental impact and provide the decision-making on the tactic decision-makingof all of the country's sustainable development. Meanwhile, my thesis has the practical value to construct the eco-system's Hidden Flow of all the country, and to calculate other gold mines's indirect flow.
