摘要
针对内蒙古地区农业干旱的特点和旱灾发生频繁的现状,以及干旱对当地农业生产所造成的严重影响,利用地理信息系统(GIS)、VisualBasic和Access等技术方法,编制了内蒙古农业干旱检索查询及旱情实时监测系统。该系统建立了历史上农区干旱信息、农区干旱指标和作物生长季(4~9月)的基本气象资料、干旱实时监测信息等数据库,实现了历史上农区干旱信息(干旱出现年份、发生季节、出现强度、出现区域、受损情况等)的综合检索查询和实时气象资料的自动采集,具有监测信息的统计、检索、旱情分析评估等功能,能实时有效地监测干旱灾害的发生、发展,并提供逐月旱情评估、任意时段旱情分析和不同年份旱情的比较分析,可为相关部门抗旱决策提供可靠的数据资源。
The inquiry and real time monitoring system of agricultural droughts in the Inner Mongolia Region was established by means of technical methods such as GIS, Visual basic and Access,Considering the characteristics of agricultural droughts and dry damage, as well as drought impact on crop growth in the Inner Mongolia Region. It consists of historical drought information, drought index and real time monitoring data in crop growing season from April to September in agricultural areas, and realized the comprehensive inquiry and the real time automatic collection and monitoring of drought information in agricultural areas, as well as the automatic real time processing of meteorological data and analysis assessment of dry damage. At the same time, the system provides the assessment of drought conditions every month and the analysis products of droughts in any time periods. It can offer reliable data for related departments.
