【題目】下圖是我國(guó)北緯30度附近兩個(gè)省會(huì)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(lèi)型以林地為主

B．動(dòng)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(huì)。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(lèi)型以草地為主，A錯(cuò)。青藏高原海拔高，熱量不足，動(dòng)植物資源少，生態(tài)環(huán)境脆弱，B、C錯(cuò)。生長(zhǎng)期短，農(nóng)作物只能一年一熟，D對(duì)。

【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(zhǎng)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(duì)。季風(fēng)強(qiáng)弱、海陸位置、緯度位置的差異，不是主要原因，A、B、D錯(cuò)。
