The standardized mortality rate showed a downward trend （APC=-1.39%， P<0.05）. The crude mortality of ischemic stroke showed an upward trend with the year （APC=3.15%， P<0.01）， and the trend change in standardized mortality rate had no statistical significance. The crude mortality and standardized mortality of hemorrhagic stroke showed a downward trend，with the mortality rate decreased at 2.43% per year and the standardized mortality rate decreased at the 4.50% per year （all P<0.05）.
