Abstract:
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.
