The article used MATLAB language to visually design the agricutural remote sensing monitoring system for Songnen Plain,the histori-cal data on crop growth in the Songnen Plain were evaluated and monitored in real time.The remote sensing monitoring system for agriculture in Songnen Plain already had main functions of monitoring of 5 classes growth index(NDVI,VCI,MVCI,RMNDVI,RPNDVI)and automatic extrac-tion of corps(corn,rice,soybean)and Songnen Plain important food crops of remote sensing information, at the same time for classification of three kinds of the surface such as wetland,forest land and grassland.The monitoring system solved the problem of processing large quantity of im-age data in the study of remote sensing information in the vegetation of the Songnen Plain,provided excellent technical support for studying the changes and regularity of vegetation characteristics in the Songnen Plain in the future.It can also be applied in other areas and imaging data stud-ies,which has good stability,fast data process,high classification accuracy.%利用MATLAB语言进行可视化设计出松嫩平原农情遥感监测系统,客观地对松嫩平原农作物生长状况的历史数据进行评估和实时监控.松嫩平原农情遥感监测系统主要功能为农作物长势监测(NDVI、VCI、MVCI、RMNDVI、RPNDVI)和自动化提取农作物(玉米、水稻、大豆)等松嫩平原重要粮食作物遥感信息,同时对3类地表(湿地、林地、草地)等分类.该监测系统解决了松嫩平原植被遥感信息提取研究中需要处理大量影像数据的问题,为未来研究松嫩平原植被特征变化和规律提供了非常好的技术支持;也可以应用于其他区域和影像数据研究中,具有稳定性好、处理数据速度快、分类精确度高的特点.
