Xiangjiang, Zishui, Yuanjiang and Lishui, flowing in mountainous region, are heavy rain rivers with frequently occurring flood water logging disasters. Based on analyzing the data of flood disasters in about ten years, some conclusions about integrate features of the flood water logging disasters are got as follows: high frequency, simultaneously occurrence and regional difference. In temporal distribution, the flood represents seasonal, annual and periodical aspects. In spatial distribution, mountain torrents repeat in upper and middle reaches in mountainous and hilly area. Flooding and water logging interweave repeat in middle and lower reaches over valley plain, coexist in the lower reaches. Furthermore, the severity and frequency of the disasters being enlarged day by day. So redution strategies are put forward in order to reduce the loss.
