【題目】下圖是我國北緯30度附近兩個(gè)省會城市年內(nèi)各月氣溫與降水量柱狀圖。讀圖回答下列各題。

【1】甲地區(qū)

A.土地利用類型以林地為主

B.動植物資源豐富,生態(tài)環(huán)境穩(wěn)定

C.農(nóng)業(yè)生產(chǎn)的有利因素為積溫高

D.農(nóng)作物只能一年一熟

【2】造成甲、乙兩地差異的最主要原因是

A.季風(fēng)強(qiáng)弱不同 B.海陸位置不同

C.緯度位置差異 D.海拔高低懸殊

【答案】

【1】D

【2】D

【解析】

試題分析:

【1】根據(jù)材料,兩城市是省會。讀圖,根據(jù)氣溫和降水資料分析,甲圖所示城市夏季涼爽,氣溫不高;冬季寒冷,年均氣溫較低,且降水集中在夏季,結(jié)合緯度可知,該地位于青藏高原,應(yīng)為拉薩。該地土地利用類型以草地為主,A錯(cuò)。青藏高原海拔高,熱量不足,動植物資源少,生態(tài)環(huán)境脆弱,B、C錯(cuò)。生長期短,農(nóng)作物只能一年一熟,D對。

【2】讀圖分析,乙圖所示城市夏季高溫多雨、冬季溫和少雨,為亞熱帶季風(fēng)氣候。結(jié)合緯度分析,該地7月份有伏旱現(xiàn)象,應(yīng)位于長江中下游平原。所以造成兩地差異的主要原因是海拔高低懸殊的地形,D對。季風(fēng)強(qiáng)弱、海陸位置、緯度位置差異,不是主要原因,A、B、D錯(cuò)。
