Fifteen villages each in the Northern(plain),Southwestern(mountainous area)and Eastern(hilly area)Zhejiang province were randomly selected.Spatial information of 871 houses in the villages and 1 080 specimen planting were extracted by remote sensing.The result demonstrated that in northern Zhejiang,the orientation of tree planted was north>west>east>south.The crown diameter of trees was 4.8-5.4 m,the distance from the crown to the wall was 0.7-1.1 m,and the projected length was 3.2-3.7 m.In the southwest Zhejiang,the orientation of tree planted was south>north>east>west.The crown diameter of the trees was 5.2-5.7 m,the distance from the crown to the wall was 1.0-1.5 m,and the projected length was 4.0-4.4 m.In the eastern Zhejiang,the orientation of tree planted was south>north>east>west.The crown diameter of the trees was 4.4-4.9 m,the distance from the crown to the wall was 1.3-1.7 m,and the projected length was 3.1-3.5 m.Sampling statistical resulted the representative models of spatial relationship between houses and specimen planting in the northern,southwest and eastern Zhejiang.
