摘要
Abstract
With the agricultural drought indices for reference, the drought weather processes appeared in 43 counties and districts of Shaanxi loess plateau from March to June, 2007 were analyzed and compared by four methods. The results showed that the calculation results of the four methods showed more severe drought than that of the statistics departments; the drought level calculated by relative moisture index was higher than the actual level shown in statistics; the drought-affected area obtained by the standardized precipitation index was larger; the anomaly percentage of precipitation and comprehensive drought index were basically consistent with the actual situation. In the calculation of the start and end dates of drought, the calculation results of relative moisture index was the same as the calculation results of water conservancy industry standards set by the Ministry of Water Resources; in the calculation of drought end date, the calculated results using the integrated meteorological drought index and the precipitation anomaly percentage index were very close to that of water conservancy industry standard set by The Ministry of Water Resources.关键词
