[ Objective ] Walls are the key components of solar greenhouse to maintain high air tempera-ture and guaranteeing the plant growth during winter. The objective of this paper is to analyze the factors af-fecting the heat insulation and storage of the wall and forcast the development of the wall in future. [ Methods ]The study on the wall of solar greenhouse was reviewed and analyzed in view of material, walling construction,form of wall surface, heat transfer in the wall, design and evaluation method. [ Result ] The construction of thewall confronted the problems like not environmentally friendly materials, low construction efficiency and quali-ty, imperfect design method, etc. [ Conclusion] The compound wall with exterior thermal insulation and thewall with single heat insulation function, which were built with the assemble materials and the heat insulatingmaterial, respectively, had not only high construction efficiency and quality, but also high land use efficiency.They were two important growing trend of the greenhouse wall. Furthermore, the research on the relationshipbetween the functions of thermal insulation and the thermal storage of the wall can help not only the under-standing of the effects of walling construction on its thermal transmission, but also propose a new design meth-od for building the wall.
