中文摘要: 根据1955?2011年安徽省18个站点气候资料,运用R/S分析方法对安徽省近56年来的降水量、平均气温等指标的冬季、夏季及年均值进行了计算分析;并利用GIS的空间分析方法分析了该区域的气候要素空间分布情况。结果表明,安徽省近56年来气候变化存在赫斯特现象,并且降水和气温及其持续性都存在空间差异,整体上,南部地区降水多,气温高,持续性强;中北部区域降水少,气温低,持续性较弱。
英文摘要: According to the climate data from 1955 to 2011 obtained from 18 meteorological stations in Anhui province, the indexes of the precipitations,average temperatures in winters,summers,and the annual average values since the recent 56 years in Anhui Province are calculated and analyzed herein with the R/S analysis methods,and then the distribution of the main climate factors within that region is analyzed with the GIS spatial analysis method. The result shows that the Hurst phenomena are there in the climate changes of Anhui Province in the recent 56 years,furthermore,the spatial differences are there among the precipitations and temperatures ; i. e. on the whole, more precipitations are there in the southern region with higher temperature and strong sustainability,while less precipitations are there in the mid-northern region with lower temperature and weak sustainability.
