After analyzing, the main land use change styles of Mu-Za 
district can be classified into three categories: (1) parent- 
polygon is divided into 2 or more children-polygons based on À à 
| vertical (or horizontal) principle border, such as shown in 3 : 
Figure 3; (2) parent-polygon is divded into several children- 
polygons based on 2 or more vertical (or horizontal) principle 
borders, such as shown in Figure 4; (3) several polygons are 
merged to one polygon, such as shown in Figure 5. Letters A, B, 
C, etc. in Figure 3, 4, and 5 denote the varied land use styles.
