Analysis on Climate Factors Change in Guizhou from 1981 to 2010

论文摘要

There is no doubt about climate change.The ecological environment in the karst region is fragile and climate change needs urgent attention.We analyzed the temporal and spatial characteristics of temperature and precipitation in Guizhou Province from 1981 to 2010.The results showed that:(1) there is an increase trend of temperature with significant during in the study periods,while there was a decreased trend of the annual average precipitation.(2) The annual precipitation change rate of has significant spatial different,there was an upward trend in the eastern region while there was a downward trend in the western region.The annual average temperature change rate has a large spatial variation,which is reflected in the upward trend in the western region.There was an increasing trend in Bijie City,Liupanshui City and Qianxinan Prefecture,while there was a downward trend in the eastern regions,especially in the central region of Guiyang and the north of Qiannan Prefecture.The Guizhou Plateau belongs to the typical karst area,which is located in the upper reaches of the Pearl River and the ecological barrier zone in the middle and upper reaches of the Yangtze River.Study on climate change in the context of global change will help to take concrete measures to promote regional sustainable development.
