中国日光温室结构优化研究现状及发展趋势

日光温室是中国设施农业的重要组成部分。日光温室的结构设计不仅影响内部环境因子和生产效益,而且对温室建造、生产成本及其结构稳定性和耐用性有直接影响。综述了地域和气候约束条件下日光温室主要结构优化设计的研究现状,如跨度、脊高、采光屋面角、采光屋面形状、墙体结构和后屋面结构等,为不同地区日光温室建造提供参考信息。同时,探讨了其计算机辅助结构分析研究状况,并分析了今后的发展趋势和待研究的问题。

Current Situation and Development on Structure Optimization of Solar Greenhouse in China

The solar greenhouse plays an important role in the facility agriculture in our country. The structure design of solar greenhouse not only affects inner environmental factors and its production efficiency but also has direct impacts on construction and production cost, structure stability and durability. This paper reviews the literature of structure design optimization for solar greenhouse under different regions and climate, such as the span, the ridge, the inclination and shape of the lighting surface, the structure of wall body and the structure of back roof, etc, so as to provide reference information for greenhouse construction in different areas. At the same time, the advances of computer-aided analysis on structural and environmental performance are introduced, too. It also analyses the development tendency and questions to be resolved in the future.
