Researching on characteristics of main climate factors in the area such as water,light,and heat can contribute to a comprehensive understanding and rational utilization of local climatic resources,which can provide the basis for utilization of water resources,agricultural production planning,and ecological environment monitoring.Based on temperature,precipitation,and sunshine duration of Hechi city from 1958 to 2013,the climate change characteristics were analyzed by linear regression,cumulative departure,and Mann-Kendall method.The results showed that the annual temperature increased remarkably,and the tendency rate was 0.11℃/(10 a),with the mutation point appearing in 1986.The increase of temperature in the four seasons was different, but the biggest increasing range of temperature appeared in summer and autumn,which were the dominant factors of the increase of annual mean temperature.The precipitation in spring,summer and autumn and annual precipitation showed a slight decrease tendency,and there was a slight increase of precipitation in winter.The annual sunshine duration decreased remarkably with the rate of-63.083 h/(10 a),with the mutation point of decrease in 1970,and there was a remarkable decrease after 1976. The seasonal sunshine duration decreased significantly as well,and the order of four seasons according to decreasing range were summer,autumn,winter and spring.
