日光温室合理前后间距计算方法的分析与验证

Analysis and verification about calculation method on distance between sunlight greenhouses

随着我国设施农业的发展,在规划和建设设施农业园区时,需要计算并分析日光温室前后之间的合理间距,在温室采光时段与土地利用率之间取得一个相对合理的温室间距参数值。该论文以新疆104团西山农牧场设施农业示范区一期规划为例,将设计的日光温室前后合理间距为分析目标,通过冬至日11:00、12:00、13:00、14:00、15:00、16:00、17:00这七个整点时刻计算出当时的太阳高度角,利用公式及建设地块自然坡降值计算出7个不同的温室间距参数值。然后综合采光时段与土地利用率,得到一个比较合理的温室间距值。应用到实际建设中并经过证实,该计算选择方案可行有效,可以为日光温室建设时前后间距的确定提供参考和依据。

With the development of agricultural facilities in China, there was the necessity of calculating and analyzing the distance between greenhouses, which is to choose a relatively reasonable parameter values among many results according to daylight time and land utilization rate. The paper took the first planning section of West Mountain Farm Facilities Agricultural Demonstration Zone of the 104th of Xinjiang Production and Construction Corps as an example to analyze the distance between greenhouses. Seven different parameter values of the dis- tance between greenhouses could be obtained through the calculation about solar elevations at 11：00, 12：00, 13：00, 14：00, 15：00, 16：00, 17： O0 and gradient value of the construction site. Combined the sunlight time and the land utilization rate, it comes to a reasonable distance value between greenhouses, which had been used and proved feasible in practice. This method could be recognized as an accordance and foundation to determine the distance between greenhouses during construction progress.
