【題目】下圖是我國北緯30度附近兩個省會城市年內各月氣溫與降水量柱狀圖。讀圖回答下列各題。
【1】甲地區
A.土地利用類型以林地為主
B.動植物資源豐富,生態環境穩定
C.農業生產的有利因素為積溫高
D.農作物只能一年一熟
【2】造成甲、乙兩地差異的最主要原因是
A.季風強弱不同 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】根據材料,兩城市是省會。讀圖,根據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,結合緯度可知,該地位于青藏高原,應為拉薩。該地土地利用類型以草地為主,A錯。青藏高原海拔高,熱量不足,動植物資源少,生態環境脆弱,B、C錯。生長期短,農作物只能一年一熟,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,為亞熱帶季風氣候。結合緯度分析,該地7月份有伏旱現象,應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。季風強弱、海陸位置、緯度位置的差異,不是主要原因,A、B、D錯。

【題目】瑪納斯綠洲是新疆最大的綠洲農耕區和國內第四大灌溉農業區,在瑪納斯河沖積扇邊緣有一條狹長的泉水溢出帶,有“千泉”之稱,人們以這里濕地中的湖泊或洼地為庫址,修建多個水庫,形成了一個規模巨大的濕地水庫群,它上接大河、下通灌區。下圖為瑪納斯沖積扇及其瑪納斯河流域示意圖。
(1)運用水循環原理簡要說明沖積扇邊緣“千泉”的形成過程。
(2)該地的泉水具有“天旱年水不少,多雨年水不多”特點,試解釋其原因。
(3)分析該地巨大濕地水庫群對流域生態環境的有利影響。
