【题目】下图是我国北纬30度附近两个省会城市年内各月气温与降水量柱状图。读图回答下列各题。

【1】甲地区

A.土地利用类型以林地为主

B.动植物资源丰富,生态环境稳定

C.农业生产的有利因素为积温高

D.农作物只能一年一熟

【2】造成甲、乙两地差异的最主要原因是

A.季风强弱不同 B.海陆位置不同

C.纬度位置差异 D.海拔高低悬殊

【答案】

【1】D

【2】D

【解析】

试题分析:

【1】根据材料,两城市是省会。读图,根据气温和降水资料分析,甲图所示城市夏季凉爽,气温不高;冬季寒冷,年均气温较低,且降水集中在夏季,结合纬度可知,该地位于青藏高原,应为拉萨。该地土地利用类型以草地为主,A错。青藏高原海拔高,热量不足,动植物资源少,生态环境脆弱,B、C错。生长期短,农作物只能一年一熟,D对。

【2】读图分析,乙图所示城市夏季高温多雨、冬季温和少雨,为亚热带季风气候。结合纬度分析,该地7月份有伏旱现象,应位于长江中下游平原。所以造成两地差异的主要原因是海拔高低悬殊的地形,D对。季风强弱海陆位置纬度位置差异,不是主要原因,A、B、D错。
