Abstract
Rainstorm and flood risk was analyzed based on information diffusion theory in recent 51 years of Yiyang. The results showed that there was not spatial difference for rainstorm risk level with 50 - 70 mm of the daily precipitation in the whole city, and the occurrence rate was above 50% ; for daily precipitation ≥80 mm, the spatial distribution of risk was inequality; for daily precipitation ≥ 200 mm, the occurrence rate was less; when annual torrential days was less than 9 d, the risk of the lakes was higher than the mountains, and annual torrential rain days was more than 10 d, the risk of the mountains was higher; the risk of severe floods caused by 10 d of daily precipitation in mountains was more than in lakes; floods caused by rainfall during April-September were different in different areas and obvious in Anhua, both mild and moderate flooding once in four years, severe flooding of 7 years; floods caused by precipitation during April-June were mainly mild and moderate flooding, and mainly in the Lake District.关键词
