内容 研究概要:North China Plain (NCP) is the main granary in China, however, NCP is confronted with water shortage problem that may lead to the fall of the crop production. Thus monitoring NCP from space is very important to know how hydrologic environment affects the crop production. NCP has been monitoring by using NOAA/AVHRR for vegetation conditions. As a result, it is clarified that surface hydrological conditions clearly affect the crop production rate revealed by NDVI. Then the surface wetness is estimated by NOAA/AVHRR and GMS/S-VISSR. The slope parameter in the scattergram between vegetation index and surface temperature is examined for NOAA/AVHRR data. The difference in brightness temperatures between 8:00AM and 10:00AM (LT) is also investigated for GMS data. Both of which are considered to be the index of surface moisture condition. The distributions of surface wetness obtained from both methods well agree with each other. The results will be used for water management such as proper irrigation practice.
