中文摘要	为实现对山东省全区域干旱的动态监测,建立了基于多源遥感数据与有序加权平均( OWA)相结合的一种新的干旱监测模型。在该模型中,首先选取植被条件指数( VCI) 、土壤水分状况指数( SMCI)和降水条件指数( PCI)三种单指标干旱指数;然后结合基于遗传算法的改进层次分析法( AGA-AHP)与移动窗口法,得到山东省区域的这三种指标权重值,进而用OWA方法计算综合遥感干旱评价指数OWA-IDI( Integrated Drought Index) 。采用综合干旱指数对山东省1982 - 2014年的干旱过程进行分析,结果表明: OWA-IDI与SPI的相关系数大于0.7,达到显著相关的程度;在33年长时间段中,发现了历史上的严重干旱年;在短时间段的时间序列上,2006 - 2014年的月序列干旱发生过程与《中国水旱灾害公报》记录的干旱事件进行对比,获得了满意的一致性;在空间上,2004年每个月的干旱区域分布与《山东统计年鉴》的降水数据进行分析、对比,验证了干旱区域分布的合理性;通过5 d合成序列的模型与月序列模型在时间上对应比较,显示了更精确的干旱监测,表明OWA-IDI在干旱评价与监测方面具有重要的应用价值。
英文摘要	In order to realize the real-time monitoring of drought in Shandong province,a new drought monitoring model based on multi-source remote sensing data and ordered weighted average ( OWA) was established. The new model of drought,first of all,Chosen the vegetation condition index ( VCI),soil moisture condition index ( SMCI) and precipitation condition index ( PCI) of three kinds of single drought index,and then based on the genetic algorithm of the improved analytic hierarchy process ( AHP-AGA) method with moving window method,got the area of Shandong province each index weight value,Finally,the integrated remote sensing drought evaluation index OWA-IDI( Integrated Drought Index) was combined by OWA method. The comprehensive drought index was used to analyze the drought process from 1982 to 2014 in Shandong province. The results showed that the correlation coefficient between OWA-IDI and SPI was greater than 0.7,reaching a significant correlation. During the 33 years,severe drought years were found in history. In the short time series,the monthly drought occurrence process from 2006 to 2014 was compared with the drought events recorded in China flood and drought disaster bulletin,and the consistency was satisfactory. Spatially,the distribution of arid regions in each month in 2004 was analyzed and compared with the precipitation data in Shandong statistical yearbook,which proved the rationality of the distribution of arid regions. The comparison of time correspondence between the model of five-day synthetic sequence and the model of month sequence showed more accurate drought monitoring. Therefore,OWA-IDI has important application value in drought evaluation and monitoring.
