摘　　要：应用哈夫模型和地理信息系统(GIS)技术,结合道路网络、绿地面积、人口分布等数据,计算城镇绿地和出行点之间的吸引力数值,研究绿地空间布局、服务能力及与城镇居民需求关系。研究表明:浙江省慈溪市观海卫镇域绿地分布不均衡,多集中于中西部,绿地数量多而面积小,其服务范围和期望到访的游人数量较多;镇域南部为风景区绿地,数量少而面积大,其服务范围和期望到访的游人数量较少;镇域北部绿地资源匮乏。基于哈夫模型与GIS网络分析技术的绿地系统研究,定量地分析了城镇绿地空间要素组成与结构,可以有效地优化城镇绿地系统布局,最大程度地发挥城镇绿地生态维护功能。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 quan- titatively 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-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.
