Abstract： Flood-water logging disaster is the most serious natural disaster in Dong-ting lake region. Disastrous conditions result from not only the intensity of hazards but also the vulnerability of disaster system, and studying the vulnerability in Dong-ting lake area has important meaning on defending and resisting disaster. According to two different years meteorological data and economic static data and exercising mathematical model, this paper assessed the vulnerability of flood water logging disaster system in different spatial-temporal scale, and make GIS map. Through analysis on spatial-temporal changes of the vulnerability of flood-water logging disaster in Dong-ting lake area, the characters of the vulnerability is discovered. The natural and socioeconomic causes for dynamic changes of the vulnerability are also analyzed, and suggestions on how to decreasing the vulnerability are also made. The findings may provide a scientific basis for policy constitution.
