Spatial Relationship between House and Specimen Planting in Villages of Zhejiang

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.
