In order to better protect brick and stone cultural relics, this paper studies the present situation of brick and stone cultural relics in the open environment in humid areas with Xi'an city wall as an example. With various textures of brick and stone culture relics and complex and changeable natural environment, it determines that the protection methods of brick and stone cultural relics should be adapted to local conditions. For example, the protection methods should be different, as the outdoor environment is different from the indoor environment or in cases when there is big difference between a humid and warm environment and a dry and cold environment. This paper attempts to analyze and study the weathering status and disease mechanism of brick and stone cultural relics in humid areas. The study shows that humid environment is the most important factor causing damage to the weathering of brick and stone relics, and all kinds of diseases are generated or aggravated by the participation of water. A high efficiency and low toxicity compound antiseptic and mildew proof agent is made up by scientific proportion, whose bactericidal and bacteriostatic effect is verified with inhibition zone, the most commonly used method in biological control experiment. Moreover, the prevention and protection methods of biological weathering of brick and stone relics are put forward. It is concluded that the study of brick and stone cultural relics in humid environment can help to better carry out management and restoration of cultural relics.
