【答案】

【1】B

【2】D

【3】C

【解析】

試題分析:【1】由圖可知,在我國主要的地形中,山脈所占的比例最大,所以山脈是構(gòu)成我國地形的骨架,故選B。

【2】我國地形的特點(diǎn)是:地形復(fù)雜多樣,以高原山地為主,各類地形交錯(cuò)分布,山地面積最大,平原和丘陵主要分布在我國東部季風(fēng)區(qū)(屬于溫帶),D錯(cuò)。故選D。

【3】山區(qū)風(fēng)景秀麗,可以開發(fā)生態(tài)旅游,山區(qū)急流水能豐富,還可以積極建設(shè)水電站,對于林區(qū)要砍伐與撫育更新相結(jié)合,大力發(fā)展林業(yè),不能過度砍伐林木,以滿足市場需要,C錯(cuò)。故選C。
