摘要
该文用图解法，以北京为例，对各种不同走向、不同长高比的建筑物，在不同季节对周围地面的遮阴范围和遮阴时数进行了估算与分析。并用相对日照时数对建筑物各方向的日照条件进行了综合排序，其结果为夏季以建筑物北侧日照条件最好，其它各方向相差不大；冬季以南侧和偏南侧日照条件最好，北侧和偏北侧最差；全年综合情况则以南侧最优，北侧最差。
Based on the proportions of height to length and trends of buildings in Beijing,shading scope and time of buildings to ground are analysed and evaluated by graphic meth-ods,According to the relative sunshining,the building s sunshine condition in each directionis also put in order.The results show that the sunshine condition at north side of buildings isthe best and there is little difference between other sides in summer;and in winter,the sun-shine conditions at south,southwest and southeast of buildings are the best, but they are theworst at north,northwest and northeast; in the whole year the south is the best and thenorth is the worst.
