摘　　要：By means of linear function and Mann-Kendall test method,the climate change characteristics of temperature and precipitation from Zhumadian meteorological station in recent 50 years were analyzed.The results revealed that annual mean temperature and extreme temperature showed increase trend,especially minimum temperature,and there was a slight increase in annual precipitation.Temperature increase was more obvious in spring than that in autumn and winter,while there was a decrease of temperature in summer.Meanwhile,precipitation went down in spring and autumn,particular in autumn,while the increase of summer precipitation was most obvious.Mann-Kendall test showed that temperature in Zhumadian had obvious increase trend in recent 50 years,while there was abrupt change in temperature in the late 1990s and fluctuation change in annual precipitation.By means of linear function and Mann-Kendall test method,the climate change characteristics of temperature and precipitation from Zhumadian meteorological station in recent 50 years were analyzed.The results revealed that annual mean temperature and extreme temperature showed increase trend,especially minimum temperature,and there was a slight increase in annual precipitation.Temperature increase was more obvious in spring than that in autumn and winter,while there was a decrease of temperature in summer.Meanwhile,precipitation went down in spring and autumn,particular in autumn,while the increase of summer precipitation was most obvious.Mann-Kendall test showed that temperature in Zhumadian had obvious increase trend in recent 50 years,while there was abrupt change in temperature in the late 1990s and fluctuation change in annual precipitation.
