天文观测中的一些耀变现象一直困惑着人类，例如活动星系核、伽马暴、引力波、快射电暴、脉冲星风星云、伽马双星等等。通过多波段或多信使的联合观测，可以对这些现象进行深入的分析，增强人类对天体演化与运动规律的理解。LHAASO实验具备对耀变现象在甚高能段的观测能力，相比同领域其它类型的实验享有独特而明显的优势。LHAASO 1/4阵列将于2018年底建成取数；全阵列也将于2020年底建造完毕。值此契机，借助于LHAASO尤其是WCDA产生的数据，可以从多个方面实现甚高能伽马天文耀变现象的观测研究。首先，将对未知耀变源进行巡天探测，争取发现大量的耀变源；其次，将对一些短时标暴进行追溯符合观测、对一些周期性辐射现象进行深度观测，探寻这些现象中是否存在甚高能辐射；然后，对一些候选耀变源进行长期监测，探讨这些耀变行为的规律。最终，还要对观测结果进行物理分析，结合理论模型，得到一批重要的科学成果。

Flaring phenomena in astronomical observations such as AGN, GRB, FRB, GW, PWN, Gamma Ray Binary, and so on, are still puzzling humans. With the help of joint campaigns such as multi-wavelength and multi-messenger, these phenomena can be analyzed in depth to enhance our understanding on the evolution and the motion of these celestial bodies. The LHAASO experiment has the ability to conduct observation of such flaring phenomena in the Very-High-Energy range, thanks to its unique and significant advantages over other types of experiments in the research field. Around a quarter of the LHAASO detector array will be completed by the end of 2018, starting to acquire the scientific data, and the full array is going to be constructed and operated in the end of 2020. On this opportunity, with the data of LHAASO, especially that of LHAASO-WCDA, we can achieve the observational study on the VHE flaring phenomenon in many aspects. First of all, unknown flaring sources will be all-sky surveyed and many of this kind are expected to be discovered. Secondly, short-time bursts are to be revisited with the low threshold data in a following-up observation manner, and some periodic gamma ray emissions from some candidate sources are to be measured in very depth. Thirdly, long-term monitoring to some candidate sources is to be implemented, to dig out whether there are some physical laws hiding in those behaviors. Finally, essential physical analysis to the observation results are to be carried out, combining the input from theorists, aiming to accomplish numerous important scientific results.
