The results showed that urban greenland was fragmented and uneven- ness. Xinshi region was fragmentary while Shuimogou region was integraL Affiliated greenland and resi- dential greenland was fragmentary , while public greenland ,production greenland and shelter greenland integraL The urban greenland was nearly randomly distributed and the shape was simple.
