近年来,鉴于长江上游森林破坏严重,农林、土壤和生态环境等方面的学者纷纷呼吁,尽快制止西南高山林区乱砍滥伐、毁林开荒等错误作法,以保护和建设西南高山林区。我们完全赞成这些意见。但那种认为由于近多年来西南森林遭到一定程度破坏,长江就有变成第二条黄河的危险的观点却世得商讨。 In recent years, in view of the serious destruction of forests in the upper reaches of the Yangtze River, academics in fields such as agriculture, forestry, soil and ecological environment have called for stopping mistaken practices such as deforestation and land reclamation as soon as possible so as to protect and construct the southwest high mountain forest areas. We fully agree with these comments. However, the view that the Yangtze River has the danger of becoming the second Yellow River due to the degree of destruction of the southwestern forest in recent years has been discussed in the world.
