In order to do comprehensive control for small watershed and services of agricultural production engineering, and master the law of climate change in the surface layer in mountain area of west Liaoning, using monthly surface temperature data from 1953 to 2012 at 7 stations in west Liaoning, the characteristics of climate change and climate mutations of monthly, seasonal and annual mean surface temperature, average maximum surface temperature and average minimum surface temperature in west Liaoning in recent 50 years were researched by analysis method of climate statistical diagnostic. The results showed that: the average surface temperature, average maximum temperature and average minimum temperature had different warming trend and variation characteristics. Climate trend rate of the average annual mean surface temperature was0.403℃/10 a. Abrupt climate of the average annual mean surface temperature was warming significantly in1987 most of the month, and there was no abrupt climate change every season. Climate trend rate of the average maximum surface temperature was 0.331℃/10 a. Abrupt climate of the average maximum surface temperature did not exist, which showed warming only in the January-April and changes smoothly in other each month. Climate trend rate of the average annual minimum surface temperature was 0.590℃/10 a. Abrupt climate of the average annual minimum surface temperature was warming significantly in each month and each season of 1993. Surface temperature rose depends primarily on the surface minimum temperature. The results had reference value to use and development of climate resource, adjustment and layout of crop populations, risk decisions of agricultural meteorology.
