| 摘 要： | Based on the monthly precipitation data for the period 1960-2008 from 616 rainfall stations and the phenology data of main grain crops,the spatial characteristics of drought hazard in China were investigated at a 10 km×10 km grid-cell scale using a GIS-based drought hazard assessment model,which was constructed by using 3-month Standard Pre-cipitation Index (SPI).Drought-prone areas and heavy drought centers were also identified in this study.The spatial distribution of drought hazard in China shows apparent east-west dif-ference,with the eastern part of China being far more hazardous than the western part.High hazard areas are common in the eastern and central parts of Inner Mongolian Plateau,the central part of Northeast China Plain,the northern part of Heilongjiang,the southeastern part of Qinghai-Tibet Plateau,the central and southern parts of Loess Plateau,the southern part of North China Plain,the northern and southern parts of Yangtze River Plain,and Yun-nan-Guizhou Plateau.Furthermore,obvious differences in drought hazard were found both within and between different agricultural zonings.

| Abstract: | Based on the monthly precipitation data for the period 1960–2008 from 616 rainfall stations and the phenology data of main
grain crops, the spatial characteristics of drought hazard in China were investigated at a 10 km×10 km grid-cell scale using
a GIS-based drought hazard assessment model, which was constructed by using 3-month Standard Precipitation Index (SPI). Drought-prone
areas and heavy drought centers were also identified in this study. The spatial distribution of drought hazard in China shows
apparent east-west difference, with the eastern part of China being far more hazardous than the western part. High hazard
areas are common in the eastern and central parts of Inner Mongolian Plateau, the central part of Northeast China Plain, the
northern part of Heilongjiang, the southeastern part of Qinghai-Tibet Plateau, the central and southern parts of Loess Plateau,
the southern part of North China Plain, the northern and southern parts of Yangtze River Plain, and Yunnan-Guizhou Plateau.
Furthermore, obvious differences in drought hazard were found both within and between different agricultural zonings. |
