合理的城市公园绿地布局，不仅有益于城市居民的生活，也有利于提升城市竞争力。本文利用2015年京津冀地区13个主要城市的公园点分布的数据以及相应的城市公园绿地面积、建成区面积等相关数据，采用GIS以及统计的手段，从城市公园绿地点分布状态、人均公园绿地面积研究了城市公园绿地的现状特征，并探讨了城市公园绿地发展的失调性问题。主要结论有：各城市公园绿地的平均最近邻指数与城市的规模大小有一定的关系；京津冀各城市的人均公园绿地面积良好，个别城市未达到全国平均水平，与城市的规模没有明显关系；京津冀的各城市的公园绿地在绿地体系内部发展失调程度随时间各城市的差异增大；京津冀地区各城市公园绿地与建成区面积增长也存在着随时间城市间失调程度差异显著增大的情况，同时整体的失调程度显著增大。

Reasonable layout of urban green space is not only beneficial to the life of urban residents, but also to enhance the competitiveness of the city. In this paper, the distribution of Beijing-Tianjin-Hebei’s green space’s points in 2015 and the data of the area of green space in 2015 etc are used to talk about these things including green space points’ location of those cities, the per capita area of green space, the disorder of green space in cities, through the GIS and statistical methods. Conclusions are as follows: the average nearest neighbor ratio of green space’s points is related to the city size; the per area of green space of these cities is at a good level; the disorder of cities’ green space is being polarization;the expanding speed of green space doesn’t match the built-up area in most Beijing-Tianjin-Hebei’s cities.
