【解析】(1)青藏高原平均海拔4000米以上,是世界上最高的高原,被称为“世界屋脊”。高山终年积雪,冰川纵横。高寒、缺氧、空气稀薄、降水较少是青藏高原主要的自然环境特点。所以气温日较差大——①早晚外套、棉衣。空气稀薄,光照强——②准备遮阳伞、墨镜。海拔高,气压较低——③有心、脑、血液系统疾病者不宜去西藏旅游。而由于青藏地区降水少,所以不必要带雨衣。故选:A(2)由于青藏高原海拔高,气候寒冷,“高”和“寒”成为本区最突出的区域地理特征,气温低也成为制约本区农牧业的主导因素,本区的农牧业为一种特殊的高寒农牧业。 受气温的制约,本区的农业主要分布在海拔较低温度较高的谷地,如雅鲁藏布江谷地、湟水谷地等,称为“谷地农业”。主要农作物为耐寒、耐旱的青稞、小麦、豌豆等。本区的牧业也为高寒牧业,主要牲畜为耐寒的牦 牛、藏绵羊等。故选:B(3)青藏地区的农作物主要有青稞(大麦的一种)、豌豆、小麦、油菜等。由于太阳光照强,昼夜温差大,青稞、小麦等作物的单位面积产量比较高。本区又是全国重要的牧区,主要牲畜有牦牛、藏绵羊、藏山羊等。故选:A
