  In this paper, we present a large-scale dynamical survey of the
trans-Neptunian region, with particular attention to mean-motion resonances
(MMRs). We study a set of 4121 trans-Neptunian objects (TNOs), a sample far
larger than in previous works. We perform direct long-term numerical
integrations that enable us to examine the overall dynamics of the individual
TNOs as well as to identify all MMRs. For the latter purpose, we apply the
own-developed FAIR method that allows the semi-automatic identification of even
very high-order MMRs. Apart from searching for the more frequent
eccentricity-type resonances that previous studies concentrated on, we set our
method to allow the identification of inclination-type MMRs, too. Furthermore,
we distinguish between TNOs that are locked in the given MMR throughout the
whole integration time span ($10^8$\,years) and those that are only temporarily
captured in resonances. For a more detailed dynamical analysis of the
trans-Neptunian space, we also construct dynamical maps using test particles.
Observing the fine structure of the $ 34-80 $~AU region underlines the
stabilizing role of the MMRs, with the regular regions coinciding with the
position of the real TNOs.
