【 摘 要 】

According to the research, during 1997 to 2006, comprehensive harnessing on water and soil conservation reduced 34.77 million m3 of flood, the rate of flood reduction is 62.7%, The amount of sediment decreased by 1.482 million tons, a decrease of 83.6%. Compared with the rate in the past, flood and sediment reduction rate has an increasing trend year by year. The rate of flood reduction during 1997 to 2006 increased nearly twice as much as that in 1970s and 1980s; the rate of sediment reduction is also significantly higher than past years. Water and soil conservation measures have a great effect in SanChuanhe River basin.
