     The study of fluid inclusions in halite is an important job in research on paleoenvironment and deposit geology, because they contain the important information concerning paleotemperature of lake water and rock components. The characteristics of plasticity of halite, however, cause many difficulties in the study. In this paper, homogenization temperature （Th） of fluid inclusions is focused on the finding out the proper research methods. Two kinds of experiments were done. One was conducted by using simple freezing condition for homogenization temperature of liquid inclusions while the other method used high temperature reformation condition based on the premise of enough reliability of the test results. The results show that the homogenization temperatures （lower than 3.6℃） of bubbles formed under different freezing conditions differ insignificantly on the condition that the inclusions are not wholly iced up. However, once the inclusions are wholly iced up, their homogenization temperatures are 47.8℃ higher than those measured under the freezing condition of –18℃. Meanwhile, the experiments also indicate that high temperature （higher than 110℃） can cause obvious changes in the Th of halite fluid inclusions. The Th of single liquid inclusions within halite obtained from slowly elevating temperature condition can represent the paleowater temperature when halite was formed, which was close to the atmospheric temperature when halite was deposited, so it can be used for paleoclimate research.
