Paper Abstract

In the present study, a detailed analysis of AVHRR-based Vegetation Health Indices and meteorological data of Huanghuai region has been carried out for the years 1981-2008. Detailed analyses of spatial and temporal drought dynamics have been carried out. The results revealed that the low-grade of droughts are common phenomena in north China's main agricultural area. Moreover, the area coverage of droughts in different seasons and different regions displayed different trends. There is a decrease tendency for soil moisture in recent years.
