摘要
目的:探索天津市三级医院的空间分布特征。方法:采用GPS定位天津市43家三级医院的地理坐标,利用GIS空间分析方法进行医院聚集性分析。结果:最近邻比率NNR=0.68,Z=-4.21,P<0.01。观测值显著大于期望值;当以各区人口密度的倒数为权重时,观测值显著小于期望值。结论:仅考虑空间位置时,天津市三级医院呈空间聚集性分布;当以人口密度的倒数为权重,其分布变为离散性分布。
Objective To study the characteristics of spatial distribution of tertiary hospitals in Tianjin. Method Geographic coordinates of 43 cases of tertiary hospitals in Tianjin were located by GPS. Hospital spatial clustering was analyzed by methods of GIS spatial analysis. Results The nearest neighbor ratio NNR was 0. 68,Z = -4. 21 ,P 〈0. 01. The observed value was significantly greater than the expected value. When weighted with the reciprocal of crowd densities of districts, the observed value was significantly lower than the expected value. Conclusion The tertiary hospitals in Tianjin showed as spatial clustering distribution when only considering the spatial location. While when weighted with the reciprocal of crowd densities, it showed as discrete distribution.
