医疗服务资源的优化配置讲求效率兼顾公平的原则，利用广州市第五次人口普查及广东省第三次国家卫生服务调查资料数据，提取社会人口、健康状况、医疗利用三大指标计测广州市居民医疗服务的存在需求和就诊需求，用Lorenz曲线和Gini系数衡量分布其均衡性。结果显示：广州市居民医疗服务总需求区域差异大，呈旧城中心区集中分布，渐向新城区扩散，边缘区分散分布的空间格局。农业人口及外来人口的医疗服务需求相对分散，老年人口的医疗服务需求呈旧城中心集中分布。

And then drawing pictograms to reflect the spatial distribu- tion and analyzing the spatial distribution of concentration and dispersion by Lorenz curve and Gini Coefficient. The results showed that： the region of biweekly health need ／ demands has a big difference in Guang- zhou. That concentrates in the central of Old City, spreads gradually to the New City, scatters in the Marginal Zone. The health services need ／ demands of Agricultural population and floating population are relative dispersion, but the older population concentrates obviously in the central of Old City.
