摘要

[Objective] The research aimed to examine climate change characteristics in western Qinling during 1967-2007.[Method] Based on the data of temperature,precipitation,sunshine duration,relative humidity and evaporation capacity derived from 17 weather stations,we analyzed the climatic change characteristics in western Qinling in the past 41 years.[Result] Increase magnitude of the annual mean temperature was 0.30℃ /10 a in the past 41 years.Annual precipitation averaged 802 mm and varied non-significantly during the 41 years,while precipitation in spring significantly decreased by 13.68 mm/10 a.Besides,annual sunshine duration and annual mean relative humidity both decreased non-significantly,in contrast to annual evaporation capacity which showed an insignificantly increasing trend.Compared among southern,central and northern areas of the western Qinling,annual mean temperature,precipitation and relative humidity showed decreasing trends from south to north,while annual sunshine duration and annual evaporation capacity showed inversely increasing trends.[Conclusion] Thus,our research could provide reference basis for ecosystem stability and related research in western Qinling.
