Abstract: Natural gas with a variety of types and functions is a clean energy that mankind strides from industrial civilization forward ecological civilization and an indispensable resource that ensures energy sources to be sustainable development. There are multiple genetic mechanisms and functions in the combustible hydrocarbon gas and incombustible non-hydrocarbon one in natural gas as a necessary accelerant for oilfield development, synthetic fuel as well as light industry and agriculture. China is very rich in natural gas resources, and six giant gas provinces have been discovered up to now. Its annual gas production rate will reach 500×10⁸m³ in about 2010, the ultimate gas resources amount to be 55.16×10¹²m³. China will become a powerful country of gas production to be worthy of the name.

Key words: China, gas resources, neotectonic movement, volcanic process
