摘　　要：以2008年3月中旬到5月下旬的MODIS晴空影像资料为数据源,采用植被供水指数法,生成邢台市旱情空间分布图。以旬为单位揭示了农业旱情的空间格局动态变化,分析了旱情动态变化的自然基础及社会经济因素,目的在于为邢台市农业旱灾管理提供科学依据。In this paper, MODIS remote sensing data from mid-March to late May 2008 were taken as the data sources, using the method of vegetation supply water index, the drought spatiotemporal pattern were generated. Took the ten-day period as the unit, the agricultural drought dynamic spatiotemporal change laws were revealed and natural and socioeco- nomic causes were analyzed, the findings may provide a scientific basis for agricultural drought disaster management in Xingtai City.
