【 摘 要 】

Wumeng Mountain Nature Reserve is a typical region with important characteristics such as national nature reserve, old revolutionary area and the important combination of natural geographical area, and it is a vulnerable and special area under the background of global warming. Based on the annual and monthly mean temperature and precipitation data of two meteorological stations in the protected area from 1959 to 2015. using linear tendency estimation, Mann-Kendall mutation test and Morlet wavelet analysis, the characteristics of temperature and precipitation change in Wumeng Mountain Nature Reserve were studied. The results show that since 1959, the temperature in Wumeng Mountain Nature Reserve has been decreasing, while the precipitation responsibility has been increasing, with the rates of-0.124 C/10a and 15.02mm/10a, respectively. The temperature and precipitation in the nature reserve have changed abruptly, and the temperature change is more obvious than precipitation. The periodicity of the temperature and precipitation change in the nature reserve is the most significant in the medium-long time scale and the inter annual change cycle, both 14a. The possible impact of temperature and precipitation changes on the nature reserve is briefly described, which provides a reference for rational planning and construction of the nature reserve, agricultural production and soil and water conservation in the area.
