综合干旱评价方法在云南省的适用性研究

Study on the Applicability of Comprehensive Drought Assessment Method in Yunnan Province

云南省是干旱高发和频发区,以2009年2月数据为实验数据,选择气象干旱和农业干旱相关指标构建综合干旱评价模型.利用2010年2月数据为验证数据,进一步对该区进行干旱监测,验证并修正综合干旱监测模型.将监测结果与《减灾年鉴》所记录的实际干旱情况对比发现,该模型监测结果与实际干旱分布与干旱强度具有很高的吻合度,能够很好地监测云南省干旱灾害分布,为抗旱救灾提供依据.

Drought in Yunnan province came in a high incidence.A comprehensive drought evaluation system was constructed by meteorological drought and agricultural drought related indexes.And data in February 2009 was used as experimental data to monitor the drought in this area.The data in February of 2010 was used as validation data to monitor drought,testing and verifying this model.While compared the monitoring results with actual drought conditions that recorded in the Disaster reduction Yearbook.It told that the monitoring results had a high agreement with the actual drought distribution and degree.And this method can well monitor the distribution of drought disaster in Yunnan province,then provide evidence for disaster relief.
