摘要

随着气候变化，气象干旱威胁农业经济发展。利用陕西省16个地市19个气象台站降水资料，选择降水距平百分率为干旱指标，计算陕西省近50 a各年的干旱指数，在此基础上分析了干旱年际变化特征，并利用GIS10.1绘制干旱强度的空间分布图。研究结果表明，陕西省夏季降水多、冬季少，多年平均降水量（陕南﹥关中﹥陕北）；1960—2013年陕南地区、陕北地区、关中地区分别出现干旱次数为15，17，13，研究区域内16个地市发生干旱的平均频率为28%，轻度、中度、严重、特大干旱发生的平均频率分别为19%，6%，1%，2%，其中绥德发生频率最高（39%）。研究结果为陕西省干旱的监测、评估、预警和抗旱减灾工作提供科学依据。

Abstract

With climate change

meteorological drought threatens the development of agricultural economy.Using percentage of precipitation anomaly index to describe drought，with precipitation data from weather stations in 16 city in Shaanxi province，annual drought indices in the recent 50 years(from 1960 to 2012)were calculated. On this basis

analyzing the interannual variation of drought

the spatial distribution characteristics of drought intensity were analyzed by GIS10.1. Here we show that summer precipitation in Shaanxi province is more than that in winter. From northern part to southern part

the average annual precipitation increased. The number of drought event was 15

16 of southern part

northern part

guanzhong area respectively during this 53 years. The average frequence of drought event was 28%. The average occurrence frequency of light

moderate

serious

extraordinary drought were 19%

2%. Among them the occurrence frequency of drought in Suide city was the highest(39%).This research will provide a scientific basis for drought monitoring

evaluation

forecast and drought resistance strategy in Shaanxi Province.
