山东省陆面实际蒸发量估算及变化特征分析
Estimation and Variation Characteristics of Land Actual Evapotranspiration in Shandong Province
摘要
Abstract
Based on the complementary relationship of evapotranspiration model,actual evapotranspiration of 17 meteorological stations in the Shan-dong Province was estimated for the period 1961-2008. Variation characteristics were further investigated by using the methods of statistical analy-sis,correlation analysis and Mann-Kendall trend test. The results show that the annual average actual evapotranspiration of the Shandong Province is about 586. 7 mm;the curve of seasonal actual evapotranspiration variation presents a single-peaked pattern with the maximum value in July;the trend of inter-annual variation is decreasing steadily,it is found that there is a step change of annual actual evapotranspiration occurred in 1991,af-ter which the decreasing rate is much bigger than that before;the decreasing trend is consistent with that in summer and autumn,but opposite in spring and winter;spatially,the actual evaportranspiration decreases gradually from coastal area to the inland,and a high evaportranspiration strip exists in the midland.关键词
