Inquiry and Real-Time Monitoring System of Agricultural Droughts in Inner Mongolia Region

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。
