摘要:

蝗灾属于毁灭性的生物灾害,它和水灾、旱灾一起构成人类社会的三大自然灾害,一旦爆发,对国家粮食安全、农民增收、社会安定可造成严重的影响。将遥感与GIS结合,对蝗虫生境特征、历史蝗灾记录、蝗害发生时有关数据进行集成和分析,可提供蝗灾时空变化、蝗灾范围、蝗灾程度、灭蝗的最佳时段等重要信息。本文重点论述遥感与GIS在蝗灾中的应用,以遥感反演的温度和水分为例来讨论蝗灾前后生境的变化状况,依靠遥感等高新技术实现飞蝗灾害监测的信息化。信息化监测与防蝗站观测相结合的方法已经成为监测蝗灾发生的最有效途径

关键词: 遥感, GIS, 东亚飞蝗, 灾害

Abstract:

Locust hazard is a destructive biological disaster It is amongst the three major natural hazards together with floods and droughts Once it outbreaks, it will severely threat to the safety of local agriculture, farmer’s income and the stability of society The combined use and analysis of remote sensing and GIS and their integration with historical records as well as some other field observational data can help to understand the characters of locust living environment, the occurrence time of locust hazard and the extent of locust hazard In recent years, locusts hazards in East Asia have become more server than before in terms of frequencies of occurrence and agriculture damages in eastern reed areas Based on statistics released by the Ministry of Agriculture, during summer and autumn of 1995~2000,about 8000 hm2 of farmland and grassland were affected by locust hazards In the summer of 2001 the affected area increased 50% and in the summer of 2002 other 10% was added in the affected areas In Dagang of Tianjin about 2400 hm2 were affected by the locusts, the most server case in the district with densities ranging from 1000 to 5000 heads/m2 ,far more exceeding the national prevention and control standards of 0 5 heads/m2 Presently, the traditional locust observation forecasting system is still used It is very difficult to deal with the new development situation of locust habitat, the increase of affected area and new outbreaks are just the cases In this paper we introduced our recent research results in using remote sensing to detect locust egg hatching conditions, soil temperature and soil moisture in combination with field observations to implement the migratory locust hazard information monitoring system

Key words: remote sensing, GIS, East Asia migratory locust, hazards
