摘要: 公园绿地可达性是衡量城市现代化发展水平、和谐人地关系的一个重要指标.了解公园绿地可达性客观影响因素及作用程度,对有效提高公园绿地可达性、充分发挥公园绿地的服务功能、促进城市健康发展具有重要意义.本文基于ArcGIS 9.3软件平台,运用网络分析法评价了沈阳市三环以内公园绿地服务面积及其服务效率,并分析了公园绿地服务面积及其服务效率随公园绿地面积、公园绿地形状、路网密度的变化规律.结果表明: 公园绿地面积与其服务面积呈显著正相关,与其服务效率呈显著负相关;公园绿地形状与其服务面积及服务效率呈显著正相关;路网密度与公园绿地服务面积呈显著负相关,与其服务效率没有显著相关关系;3个影响因子中,对公园绿地服务面积的影响程度依次为:公园绿地面积>路网密度>公园绿地形状,对公园绿地服务效率的影响程度依次为:公园绿地面积>公园绿地形状>路网密度;公园绿地面积是其服务面积及服务效率的最重要影响因子.

Abstract: Urban park accessibility is an important indicator to measure the level of urban modern development, and the harmonious relationships between people and land. It is meaningful for efficiently increasing urban park accessibility, fully providing services functions of urban park and promoting healthy development of cities to understand objective influencing factors of urban park accessibility and its extent of impact. The service area and service efficiency of urban parks in three-ring area of Shenyang City were evaluated basing on ArcGIS 9.3 software platform and network analysis methods. The regularity of the service area and service efficiency of urban parks changing with the urban park area, urban park shape and road network density were analyzed. The results showed that urban park area had significant positive correlation with service area and significant negative correlation with service efficiency. Urban park shape had significant positive correlation with service area and service efficiency. Road network density had significant negative correlation with service area of urban parks, but had no significant correlation with service efficiency. Based on the extent of impact on urban park service area, the importance of three influencing factors was in the order of urban park area> road network density > urban park shape. Based on the extent of impact on urban park service efficiency, the importance of three influencing factors was in the order of urban park area> urban park shape > road network density. Urban park area was the most important influencing factor for the service area and service efficiency of urban parks.
