The Tree of apartment building is important to achieve a sustainable design for urban environment and to increase residental satisfaction. This study presents the solar shading effect of trees for multi-layer planting. The site for field test is located in Junju, Korea. Four main factors, daylight, illumination, temperature and relative humidity for planting, is tested for 3 months from June to August. Results from the field test are as following; The highest value to block the sunlight is at mean 553.1 W/m2 in shading space under Prunus serrulata var. spontanea, that height is 8.3 m and crown diameter is 6.7 m and The lowest of that is at mean 253.8 W/m2 under Malus prunifolia (willd.) Borkh. The difference of temperature between sunshine space and shade one ranged from 0.6°C to 6.7°C because of tree in Summer. The results shows that solar shading effect of trees can be used to estimate the change of plant growth condition for ground cover planting.
