Natural resources in Yunnan
Yunnan not only has more plant species of tropical, subtropical, temperate, and frozen zones than any other province in the country, but also has many ancient,
endemic plants, as well as species introduced from foreign countries. Among the 30,000 species of plants in China, 18,000 can be found in Yunnan. Yunnan is also home to a variety of animal species, most notably the southeast Asian gaur, a giant forest-dwelling ox, the tiger, and the Asian elephant.
More than 150 kinds of minerals have been discovered in the province. The potential value of the proven deposits in Yunnan is 3 trillion yuan, 40 % of which come from fuel minerals, 7.3 % from metallic minerals, and 52.7 % from nonmetallic minerals.
Yunnan has proved deposits of 86 kinds of minerals in 2,700 places. Some 13% of the proved deposits of minerals are the largest of their kind in China, and two-thirds of the deposits are among the largest of their kind in the Yangtze River valley and in south China. Yunnan ranks first in the country in deposits of zinc, lead, tin, cadmium, indium, thallium, and crocidolite.
Yunnan has sufficient rainfall and many rivers and lakes. The annual water flow originating in the province is 200 cubic kilometers, three times that of the Yellow River. The rivers flowing into the province from outside add 160 cubic kilometers, which means there are more than ten thousand cubic meters of water for each person in the province. This is four times the average in the country. The rich water resources offer abundant hydro-energy.
