摘　　要：城市空间影响势力范围的界定是认清城市与腹地、城市与城市间相互关联的基础。借鉴Okabe的有层次组织空间数据的思想,采用2010年我国城市综合实力指数为权重构建我国城市空间影响的分级加权Voronoi。研究表明:①我国城市空间影响势力范围的等级层次分为4级,百强城市为第一级局部中心城市,17个第二级局部中心城市,3个第三级局部中心城市,1个第四级中心城市为上海;②城市空间影响的势力范围与城市密度成反相关,并受到相邻高权位城市的"侵蚀";③城市的地理区位条件也是影响其势力范围的重要因素。The delimitation of the sphere of spatial influence of cities is essential for understanding the interrelationship＇between city and its hinterland, as well as city and city. Following Okabe＇s view of hierarchical spatial data, the paper created grading weighted Voronoi diagram of the sphere of spatial influence of the top 100 powerful cities in China by using its comprehensive strength indexes in 2010 as the weights. The results showed that： （1）the hierarchy of the sphere of spatial influence of cities were divided into 4 levels in China, the top 100 powerful cities were the first regional central cities, 17 cities were the second, 3 cities were the third, and Shanghai was the fourth level of central city, （2）the sphere of spatial influence of cities was inversely correlated with urban density, and its region would be encroached by adjacent higher weight cities, and （3）the geographical area is an important factor in delimitating the sphere of spatial influence of cities.
