The Beijing-Tianjin-Hebei region has been a water-poor area for many years. In recent years, with the implementation of the "strictest water resources management system",the local agricultural production and social and economic development have been severely restricted. Therefore, systematically studying the drought situation in the Beijing-Tianjin-Hebei region, accurately predicting and assessing the laws and hazards of drought occurrence, can provide scientific basis for regional water resources regulation and decision-making by relevant departments, and provide reasonable solutions for future agricultural water use. Based on the monthly MODIS NDVI and LST data from May to October in 2000-2016, this paper uses the TVDI model to monitor droughts in the Beijing-Tianjin-Hebei region, and discusses the temporal and spatial distribution of droughts. On this basis, combined with MCD12Q1 Land cover type 2 land cover data In the Maryland classification scheme, the land cover classification was revised and merged into two categories:agricultural land and non-agricultural land, as a base map for extracting TVDI of agricultural land, and further analysis of the disaster situation of agricultural land. The results show that after 2013, the proposal of the "strictest water resources management system" has a great impact on agricultural land in Beijing-Tianjin-Hebei Region, which will lead to an increase in the arid area of agricultural land to a certain extent.
