根治长江黄河水患必须标本兼治 重在治本

TREATING CHANGJIANG RIVER AND YELLOW RIVER BY LOOKING FOR BOTH ITS ROOT CAUSE AND SYMPTOMS

根治长江黄河水患必须两手抓:一手抓水利工程建设,保证不发生洪涝灾害,即治标;一手抓植树造林,培育植被,涵养水源,防止水土流失,建设好生态环境,即治本;两手抓要标本兼治,重在治本。江河上游的植被必须具备以下条件,即针阔混交林、成熟林和高覆盖率(50%以上),才能真正发挥涵养水源,防止水土流失的作用。

Treating Changjiang River and Yellow River should consider the water conservancy project and silviculture,the former is to control flooding for symptom treatment,the latter is to increase vegetable cover for root cause treatment.The vegetable covers of the upper areas of rivers should be mixed forests, higher cover rate(above 50%),which may play the roles of control water erosion.
