Agricultural Drought Remote Sensing Monitoring and Analysis Platform in Northwest China Base on FY-3 Data

Abstract

The eastern part of Northwest China, located on the edge of the East Asian monsoon region with low precipitation and high variability, is one of the regions with the most frequent droughts in China. The drought causes huge agriculture losses in this region. We created agricultural drought remote sensing monitoring and analysis platform(ADMP) in Northwest China base on FY-3 Data in order to improve the universality, comparability and automation degree of agricultural drought monitoring based on remote sensing in Northwest China, meanwhile, an optimization scheme for drought monitoring based on the coupling of climate division and vegetation types was proposed according to the applicability evaluation of multiple drought monitoring models, for giving full play to the role of FY-3 series satellites. The ADMP consists of three parts, namely data support system, monitoring and analysis system and product release and display system. The function of these systems is achieved using plug-in design concept, which build server-side plug-in framework, formulate business plug-in integration specification as well as carry out modular packaging and service transformation of algorithms and data resources, Therefore, It realizes the configurable, expandable, pluggable goals of the new business modules, and effectively avoids repeated construction caused by the addition of new applications in the traditional mode.The ADMP is composed of three subsystems and twelve sub-functional modules. It can automatically produce seven drought indices products with multiple time scales (day, five days, ten days and month). Furthermore, the ADMP products include thematic maps, statistical tables and monitoring reports at the four levels of the northwest region, province, city, and county. The ADMP products consistent with the actual situation in drought range and intensity through the monitoring lots of drought cases.
