摘要:
基于河池市10个气象站1961-2010年的日照时数数据,采用线性趋势分析、逐步回归分析等方法,依托GIS技术对河池市近50a日照时数的气候倾向率、年代际变化趋势进行分析。结果表明:河池南部及东南部的都安、宜州、巴马、大化县的年日照时数较多(大于1200h),北部及西北部的天峨、南丹、环江县的北部年日照时数较少(小于1000h);全市各地区的年日照时数变化速率值在-82.66 h/10a~19.8 h/10a之间;河池各县的日照时数年代际变化特征各不相同,其中东兰、凤山和都安大部地区的年日照时数的四个年代都是呈现下降的变化趋势。
Abstract:
Based on the daytime data of 10 meteorological stations from 1961 to 2010 in Hechi, this paper used linear trend analysis and stepwise regression analysis to study the climate tendency rate and interdecadal trend of the sunshine hours in recent 50 years in Hechi by means of GIS technology. The results showed that in southern and southeastern Hechi, the number of days in Duan, Yizhou, Bama, and Dahua were more than 1200h, while the days in the northern and northwestern Tian’s, Nandan and Huanjiang were less than 1000h. The annual sunshine hours change rate in all parts of the city was between -82.66 h/10a and 19.8 h/10a. The interdecadal changes of sunshine hours in various counties of Hechi were different, and the four decades of the annual sunshine hours in the Donglan, Fengshan and Duan were all decreasing.
