摘　　要：目的探讨气候因素对自发性脑出血发病率的影响。方法对我院4年间住院的1139例脑出血患者按照发病的月份进行统计,并对相应时间的主要气候因素(气压、气压差、气温、湿度)的变化做统计分析,对于二者的变化趋势做相关性分析。结果 (1)自发性脑出血发病率与气压呈明显的正相关(相关系数0.89278),与气压变化呈正相关(相关系数0.67651);(2)发病率与气温呈明显的负相关(相关系数-0.88399),与气温变化无明显的相关性(相关系数-0.36596);(3)发病率与湿度无明显的相关性(相关系数-0.11005)。结论自发性脑出血发病率与大气压、气压变化和气温有关,高气压、低温和气压变化较大时自发性脑出血发病率较高。Objective To investigate climate faetors effect on attack rate of spontaneous cerebral hemorrhage. Methods To statistics attack rate of 1139 spontaneous brain hemorrhage case for 4 years in our hospital on month, and to statistics the trend of climatic factors （air pressure, differential pressure, temperature, humidity）corresponding time, then to study the dependability between of them. Results The attack rate of spontaneous brain hemorrhage had positive correlation with air pressure（ correlation coefficient ：0.89278 ） and differential pressure（ correlation coefficient ： 0.67651）, negative correlation with temperature （correlation coefficient -0.88399 ）, and uneorrelated with change of temperature （correlation coefficient： -0. 36596 ） and humidity （correlation coefficient： -0. 11005 ）. Conclusion The attack rate of spontaneous brain hemorrhage coneernes with air pressure, differential pressure and temperature. It is to advance when high air pressure, high differential pressure and temperature.
