Abstract: ：For scientific planning green space layout，application of the Huff Model and GIS techniques combined with traffic networks，green land areas，and population distribution of Guanhaiwei Town in Zhejiang, the affinity value between green land position and departure point of visitors was calculated. Also，green land spatial patterns，service capability，and relationships with residential requirements were studied. Based on the Huff Model and with the help of network analysis functions，the green land layout scenario was used to quantitatively analyze composition and structure of the green land spatial element and to optimize the green land layout. Results showed that green land distribution was uneven being concentrated mostly in the middle?鄄west part of the town where the green land count was large，however the area was small, and the serving scope and expected number of visitors were greater. In the south，there were a small number of natural landscape zones， but their area was large with service scope and expected number of visitors being limited. In the north， there were fewer green land resources. Based on the Huff Model by the help of network analysis function，the composition and structure of the urban green land spatial element could be analyzed quantitatively to optimize the green land system layout and maximize the ecological protection function of green land in Guanhaiwei Town.
