摘　　要：根据我国棉花生产基地鲁西北地区棉花雹灾保险工作的需要，提出并设计建立了棉田雹灾遥感监测理赔系统。整个系统由棉田航空遥感调查、雹灾范围和程度的雷达监测、棉田雹灾损失计算机分析等３个子系统组成。它们的协同运行在１９９０年６月２３日的较大雹灾理赔过程中取得了较好的效果。本文主要论述该系统建立的技术方法和运行的试验结果。An integrated remote sensing monitoring technical system is built up inNorthwest Shandong Province which is the majorest cotton area of our country. The system can be used to survey the cotton distribution, monitor the disaster cau-sed by hail,analyse and output the area and levels of cotton lost.First,the subsys-tem of cotton distribution surveying is introduced based on aerial remote sensing. Then the subsystem of hail disaster monitoring is described.It is applied to followthe tracks of hail cloud such as its height, thickness.motion velocity and direction. The levels and range of hail can be defined with it.In the third subsystem whichis information system of analysis of cotton loss caused by hail,cotton field databaseand hail database are built up respectively.The cotton field loss is obtained bv in-tersection operation of the two databases,supported by pc ARC/INFO software. InJun. 23,1 990.the system was used to monitor the cotton field loss caused bv hailwhen a greater hail process took place.The application showed that the system wasboth reliable and accurate.
