Abstract In order to understand the major type of solar greenhouse in Shanxi Province and its
existing problems，we investigated the types and current situation of solar greenhouses，and analyzed
the rationality of 3 important structure designs including lighting roof，wall style and digging depth．
The result indicated that there were many types of solar greenhouse，which could be mainly divided
into 2 kinds：stand slope type and arch round type according to the structure of lighting roof．Judging
from the wall style structure，it could be divided into the earth wall and brick wall 2 types．The already
constructed solar greenhouses in Shanxi Province were lack of necessary analysis and specification in
construction．There were mang problems．The lagging jacks in front of the greenhouses shaded off
more light，the over digging made the depth too deep，and the wall bodies were too thick．We should
develop a standardized construction plan for solar greenhouse according to the climate characteristics of
Shanxi Province，so as to guide the construction of new solar greenhouses and optimize the reformation
of existing solar greenhouses.
