摘要

Based on data of temperature and precipitation in Huanren County from 1953 to 2010,linear trend analysis and mutation detection of temperature and precipitation sequence were carried out using linear trend,Mann-Kendall detection and dryness of the de Martonne method. The results showed that during 1953- 2010,annual average temperature,annual average maximum and minimum temperature in Huanren County showed an increasing trend; annual precipitation showed a decreasing trend; there was a downward trend in annual dryness. The mutation of annual average temperature,annual average maximum and minimum temperature appeared in 1978,1987 and 1982 respectively; there was no mutation of annual precipitation and dryness. On the whole,the climate of Huanren County tended to be warm and dry over the past 58 years.
