The invention provides a method for producing aromatic hydrocarbons and/or liquid fuels through light hydrocarbon dehydrogenation aromatization, which comprises the following steps: 1) under dehydrogenation reaction conditions, carrying out dehydrogenation reaction on light hydrocarbon material flow to obtain material flow containing olefin; and 2) under aromatization reaction conditions, contacting the material flow containing olefin with an aromatization catalyst, and carrying out oligomerization/aromatization reaction to obtain a material flow containing aromatic hydrocarbon and/or liquid fuel. According to the method, dehydrogenation and oligomerization/aromatization are separated and executed step by step under different conditions, a zeolite molecular sieve loaded with an active metal component is used as an aromatization catalyst, and under an optimal low-temperature aromatization condition, the high alkane conversion rate, the high carbon utilization rate and the high single-cycle aromatic hydrocarbon production capacity can be obtained through the method disclosed in the invention; and the catalyst is slow in deactivation, long in one-way service life, easy to regenerate and good in multi-cycle stability.
