| 摘 要： | 利用山东省潍坊市1971-2009年气象观测资料,以及各县市、乡镇街道的历史灾情记录和社会经济数据,选择适合研究区域的干旱判别指标,建立了干旱灾害评估模型。以Arc GIS9.3为开发平台,SQL Server 2005为干旱评估的信息数据库,并利用Delphi7.0等软件工具开发了基于GIS的潍坊市气象干旱评估系统,对研究区域进行干旱灾害预警和灾害损失评估。

| Abstract: | Based on 1971—2009 data of conventional observation and automatic meteorological stations,the historical drought records;the social and economic data of Weifang City,Shandong Province,a drought index is defined and also a drought prediction model is established.With Arc GIS9.3 as the data processing platform,SQL Server 2005 as the information database,and utilizing Delphi7.0 software,a drought evaluation system basing on GIS is developed,and the early warning and loss estimation of drought disaster is discussed in Weifang City. |
