近年来，桑干河灌区因地下水超量开采，地表水水源严重不足，致使水利用系数低。采用以防冻害为重点的渠道防渗技术可减少水资源浪费。

In recent years, the severe lack of water resources on the ground surface due to the over - exploitation of underground water in the Sangganhe irrigation area has resulted in the low coefficient of water use. The application of anti - seepage with lining canal technology focusing on preventing freezing can reduce the waste of water resources.
