Taking the harm of termite decay in gas pipeline in southern city as an example, the hazard analysis of termites in gas pipeline in southern area was investigated and analyzed. Termite species harmful to gas pipeline for the termites Taiwan milk termites. Termites in the season, ants winged by urban lights attract, paired, nesting in the green belt, worker ants foraging process is laid in the green belt and road gas pipeline barrier, and gradually wear PE pipe, resulting in Gas leak. In termites damaging termites in southern areas, the laying of gas pipelines should do a good job termite control and strengthen the latter part of the pipeline maintenance work, as well as to increase publicity science popularization of termites.
