The accessibility of urban park green space is an important indicator to reflect how much the natural service supplied by parks could be enjoyed by citizens conveniently and fairly. This paper took Shenyang Tiexi District as an example to evaluate the accessibility of urban park green space based on QuickBird imagery and GIS software, with four modes of transportation, walking, non-motor vehicle, motor vehicle and public transport being considered. The research compared and analyzed the distribution of the accessible area and the accessible people of park green space. The result demonstrated that park green space in Shenyang Tiexi District was not enough and the distribution was not even. To be precise, the accessibility in southwest part and central part was relatively good, that in marginal sites was worse, and that in east part and north part was the worst. Furthermore, the accessibility based on different modes of transportation varied a lot. The accessibility of motor vehicle was the best, followed by non-motor vehicle and public transport, and walking was the worst. Most of the regions could be reached within 30 minutes by walking, 15 minutes by non-motor vehicle and public transport, and 10 minutes by motor vehicle. This paper had a realistic significance in terms of further, systematic research on the green space spatial pattern optimization.
城市公园绿地可达性是反映公园所提供的自然服务能被市民便捷、公平享用程度的重要指标。本文以沈阳市铁西区为例，基于快鸟影像和GIS软件，考虑步行、非机动车、机动车和公共交通四种交通方式，对城市公园绿地可达性进行评价。研究对比分析了公园绿地可达面积和可达人群的分布情况。结果表明，沈阳市铁西区公园绿地不足且分布不均。具体而言，西南部和中部可达性相对较好，边缘地区较差，东部和北部最差。此外，基于不同交通方式的可达性差异较大。机动车可达性最好，其次是非机动车和公共交通，步行可达性最差。大部分区域步行30分钟内、非机动车和公共交通15分钟内、机动车10分钟内可到达。本文对于进一步系统研究绿地空间格局优化具有现实意义。
