【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、纬度位置的差异，不是主要原因，A、B、D错。
