摘要
Abstract
By using monthly precipitation data in Boketu Region during 1971 -2010 and statistic method, the variation trend of annual and seasonal average precipitation were analyzed. The results showed that precipitation is continuously decreasing with the average rate of 16. 5 mm/10a, the deceasing rate of summer and autumn are 26.2% ,9.3 mm/lOa; spring and winter increased with the rate of 2.8, 1.6 mm/10a respectively; light-drought appeared in 1974, 1979, 1992, 1995, 2000, 2001; mid-drought occurred in 1999, 2004; severe-drought appeared in 2007.关键词
