摘要: 为了对湖北省干旱灾害进行有效的监测,研究开发了一个基于WebGIS的湖北省干旱灾害监测与分析系统,应用GIS技术对无测站地区气象因子进行精细化模拟,采用降水距平百分率(Pa)、相对湿润度指数(Mi)、标准化降水指数(SPI)、综合干旱指数(Ci)、Palmer(PDSI)干旱指数这五种干旱指标来监测湖北省旱情;经过运行检验,本系统能对湖北省的干旱情况进行有效地监测,其运行速度快、旱情诊断准确,将在干旱监测业务中发挥较大作用。

Abstract: In order to effectively monitor drought information in Hubei province,a drought monitor and analysis system based on WebGIS was exploited.In the system,meteorological factors of no-station area were refined simulated by GIS techniques.Precipitation Anomaly Percentage(Pa),Relative Moisture index(Mi),Standard Precipitation Index(SPI),Composite Index(Ci) and Palmer Drought Severity Index(PDSI) were applied to reflect comprehensively the true drought circumstances in Hubei province.It was confirmed that the drought monitoring system could correctly reflect drought circumstances of Hubei province.With high running speed and accurate diagnosis of drought circumstances,it will play an important role in drought monitoring.
