China's copper distribution
China's copper mines are widely distributed, and all provinces, autonomous regions, and municipalities other than Tianjin, which have been identified as minerals, have different degrees of distribution. Among them, Jiangxi, Tibet and Yunnan provinces and other three provinces and regions accounted for 47.1% of the country's copper reserves (by the end of 1996 reserves statistics, the same below). Copper reserves also include Gansu, Anhui, Inner Mongolia, Shanxi, Hubei, Heilongjiang and other 6 provinces and regions, with a total reserve of 20.198 million tons, accounting for 32.3% of the country's copper reserves. The reserves of the above 9 provinces and regions account for 80% of the total copper reserves in the country. Judging from the distribution of the six major administrative regions, copper ore reserves are most widely distributed in East China and Southwest China. Reserves in the two major administrative regions account for 60.9% of China’s total copper reserves. The ratio of copper reserves in major administrative regions is: North China 11.4% in the district, 6% in the Northeast, 31.4% in the East China, 9.8% in the South Central, 29.5% in the Southwest, and 11.9% in the Northwest. From the perspective of the three economic zones, the distribution of copper in China has obvious regional differences. The three economic zones are divided according to the “China Encyclopedia·China Geography†volume (1993): The eastern coastal areas include Liaoning, Hebei, Beijing, Tianjin, Shandong, Jiangsu, Shanghai, Zhejiang, Fujian, Guangdong, Guangxi, and Hainan. Provinces, districts and cities (excluding Taiwan Province); the central region includes 9 provinces and autonomous regions including Heilongjiang, Jilin, Inner Mongolia, Shanxi, Henan, Anhui, Jiangxi, Hubei, and Hunan; and the western region includes Shaanxi, Gansu, Ningxia, Qinghai, and Xinjiang in the northwest region. There are 9 provinces and autonomous regions in Sichuan, Guizhou, Yunnan and Tibet in the Southwest. The ratio of reserves in the three major economic zones is 9.1% in the eastern coastal zone, 49.6% in the central zone, and 41.3% in the western region.
