为探索关于新疆日光温室间距的合理计算方法,用自带地理参数的SketchUp建筑软件模拟项目区日光温室的光影,分析出前后合理间距,把分析结果与传统公式计算值相比较。结果表明:与SketchUp建筑软件分析结果相比,采用温室间距传统公式法其间距计算结果存在较大误差。根据生产实践得知,按照公式计算出的数值偏小,温室采光面不能满足冬至日当天满窗照射4h采光要求。用SketchUp建筑软件分析出的温室间距较接近合理值,刚好满足冬至日当天满窗照射4h要求。表明SketchUp软件可实现优化新疆日光温室间距的建模分析。
In order to get more reasonable value of Xinjiang greenhouse spacing,taking a kind of reasonable greenhouse space,after comparison of the two results,the one is SketchUp software simulation,the other is the traditional.The results showed that by using the traditional formula method S=H/tg alpha-L1-L2,greenhouse distance calculation results had some errors,according to the actual production practice,the calculation results were smaller,it showed that the greenhouse lighting surface couldn't meet full window irradiation for 4hours in the winter solstice day.The analysis with the SketchUp architecture software greenhouse spacing was close to the reasonable value,just to meet full window irradiation for 4hours in the winter solstice day.SketchUp software could realize the optimization analysis in spacing of sunlight greenhouse in Xinjiang.
