尽管近年来我国地质工作者发现了一大批矿产地,但我国矿产资源供需紧张总体局面依然没有改变,特别是关系国家经济命脉的石油、铜、铝、钾盐等大宗矿产供需矛盾突出。中国地质调查局副局长张洪涛介绍说,随着我国经济的快速发展,对矿产资源出现巨大需求,并呈快速增长态势,主要矿产资源供需矛盾日益突出,进口量逐年攀升。目前我国大宗矿产对外依存度不断提高,我国铜消费的40%、石油消费的1/3、钾盐消费的90%以上都需依赖进口。张洪涛认为,当前我国矿产品的供需格局是“大米白面
Despite the discovery of a large number of mineral resources in recent years, the general situation of tight supply and demand of mineral resources in our country remains unchanged. In particular, the contradiction between the supply and demand of major minerals such as oil, copper, aluminum and potash, which are related to the national economic lifeline, has been prominent. Zhang Hongtao, deputy director of the China Geological Survey said: With the rapid economic development in China, there has been a huge demand for mineral resources and a rapid growth. The contradiction between the supply and demand of major mineral resources has become increasingly prominent, and the volume of imports has been rising year by year. At present, China’s dependence on foreign large-scale mineral resources continues to increase, China’s copper consumption 40%, oil consumption 1/3, more than 90% of potash consumption will need to rely on imports. Zhang Hongtao believes that the current pattern of supply and demand of mineral products in China is ”white rice flour
