(28分)智利是世界上最狭长的国家,西部是较低的海岸山脉,东部是高峻连绵的安第斯山脉,两条山脉之间是狭长的纵谷;自然景观大致以30°S和40°S纬线为界,北部荒漠、中部硬叶林、南部阔叶林。根据智利地理位置示意图,结合所学知识,完成(1)~(4)题。

(1)从智利北部到南部,在水平方向上自然景观的变化体现了_____的地域分异规律,其主要影响因素是_____。影响智利南部的气压带或风带是______,智利南部的气候类型是_________,(8分)

(2)智利是世界四大产鱼国之一,北部海域产量最高,其原因是_________。智利南部是智利重要的纸浆生产基地,影响其布局的主导区位因素是_____。(6分)

(3)世界最大的地面天文学观测装置位于智利北部阿塔卡马沙漠中的查赫南多尔高原,海拔5000米,该地是世界上最理想的天文观测点。简述该地适合天文观测的大气条件。(6分)

(4)智利是世界主要的新鲜水果出口国,主要销往美国和欧洲,其水果生产主要集中在中部地区。简述智利中部成为美国和欧洲新鲜优质水果供应地的自然条件。(8分)

答案

(1)从赤道到两极(纬度地带性)(2分),热量(2分),西风带(2分);温带海洋性气候(2分)

(2)(受离岸风影响)深层海水上涌(形成上升流),饵料丰富(4分);原料(2分)

(3)终年无雨(降水少,晴天多),大气变化比较稳定(气温年较差小),透明度高(大    气稀薄)。(每点2分,共6分)

(4)①水果生长期内光热充足,②昼夜温差较大;③水分适宜;④与北半球季节相反;⑤病虫害少(周边独特的天然保护屏障)。(每点2分,共8分)

题目分析:

(1)读图,结合材料分析,从智利北部到南部,景观植被依次是热带荒漠带、亚热带常绿硬叶林带、温带落叶阔叶林带,自然带的变化是以热量为基础的,体现了从赤道到两极的地域分异规律,也叫纬度地带性分异规律。读图,智利南部位于40°-60°的大陆西岸,受盛行西风带控制,属于温带海洋性气候。

(2)智利北部位于东南信风带影响区,受离岸风影响,深层海水上涌,形成上升流,鱼类饵料丰富,形成世界性大渔场,所以鱼产量高。南部纸浆生产是为了靠近原料产地,用林木作用生产的原料。

(3)读图,结合前面分析,智利北部属于热带沙漠气候,终年无雨或降水少,晴天多。受副热带高压带控制,大气变化比较稳定,气温年较差小。位于高原上,海拔高,大气稀薄,透明度高。适宜天文观测。

(4)读图,智利中部属于地中海气候,夏季水果生长期内光热充足,降水少,晴天多,昼夜温差较大,有利于养分的积累。水分适宜,灌溉水源充足。位于南半球,与北半球季节相反,便于反季节上市。周边有独特的天然保护屏障,病虫害少,水果品质质量好。
