Effects of Soil and Water Conservation on Lessening Flood and Water Logging Disasters in Wulijimulun River Watershed

１９９８年７—９月，乌力吉沐沦河流域降了１００ａ不遇的特大暴雨，造成该流域严重的洪涝灾害。洪水过后，在巴林左旗和阿鲁科尔沁旗选择典型小流域进行了调查和分析。结果表明：所有治理较好的小流域各项水保措施皆发挥了显著作用，蓄水保土和防洪效益明显，极大地减轻了洪水危害和洪灾造成的损失。

The biggest rainstorm in this century occured in Wulijimulun river watershed in Sev.-Sep., 1998, has caused serious flood and water logging disasters. Arter the flood, surveys and comparative analysis were carried out in two counties of Balinzuo and Alukeerqin by selecting the typical small watesheds. The results indicated that, in those better comprehensively controlled small watersheds, every practice had brought about the apparent effects upon water storage and soil conservation as well as flood prevention, thus reducing flood threats and dsmages caused by flood disasters. And at the same time, some suggestions for doing a better work on soil and water conservation are presented.
