According to the computer simulation technique and the calculating methods in greenhouse lighting theory, the article discussed the design principles of a simulation system, expounded the main structure and the key techniques of the system, and explained how to realize the system. As a special design system, the computer simulation system was of strong practicability.By calculating and analyzing the structure parameters of all kinds of greenhouses, including multi\|span, lean\|to greenhouse, symmetric and unsymmetric greenhouse, the quantity and the distributing character for daylight in a greenhouse were confirmed through a new methods, and the best structure parameters for daylighting of a greenhouse were optimized. The research could be a scientific basis and analyzing tools for optimizing design model of a greenhouse structure and for productive managements.
