根据南召县水土保持科学试验站23年的实测资料,结合青杠扒流域的水沙年际变化及年内分配特点,采用时段对比和相似降雨次洪水对比分析两种方法对该流域综合治理前后的水沙变化进行了研究,得出青杠扒流域水沙变化的原因主要是较为完善的水土保持综合防治措施作用的结果,并对该流域综合治理措施配置进行了评价。
According to the measured data of 23 years of scientific research station of soil and water conservation in Nanzhaoxian County and the interannual variation of water and sediment in Qingbabachu River Basin and the characteristics of distribution during the year, two methods were used to compare the time before and after flood control It is concluded that the main reason for the variation of water and sediment in Qingbazhu watershed is the result of a more comprehensive water and soil conservation comprehensive prevention and control measures.
