今年,某省决定完成“退耕还林”170万亩,这样做的目的是(  )

A.改善生态环境

B.发展畜牧业

C.发展旅游业

D.提高植树造林的积极性

答案

我国大部地区自然环境先天不足,生态脆弱,受到人为破坏以后,原始植被很难恢复,造成严重的水土流失与沙漠化.目前水土流失与沙漠化面积不断扩大,不但严重地制约了当地经济的发展与人民生活水平的提高,而且也危及全国环境建设.为此,国家决定在不适于发展农业的地区,如黄土高原区、西部山区的坡度大于25度以上的坡耕地,一律要退耕还草、还林.林区以及广大草原地区,已经开垦的农田,必须退耕,适于发展林业的植树,适于发展牧业的种草,使那里生态环境得到恢复.鼓励居民改善自己居住地的生态环境,为发展经济创造环境条件.这一举措是通过改变不合理的土地利用类型与方式,初步达到了保护生态和提高农牧民生产与生活水平的双重目的.最根本的目的是维护生态平衡.

故选:A.
