读我国气候类型分布图回答:(9分)

(1)写出下列气候类型名称:

A.             C.             D.             

(2)A与C的分界线大致相当于        mm年等降水量线,C与D的分界线大致相当于     mm等

降水量线,经过             (山脉)                (河流)。

D的气候区熟制就                

答案

(1)温带大陆性   , 温带季风  ,亚热带季风       

(2)400 , 800 ,秦岭 ,淮河 ,一年二熟或一年三熟

题目分析:

气候复杂多样,是我国气候的主要特征之一.我国地域辽阔,地跨众多的温度带和干湿地区,加上我国地形复杂,地势高低悬殊,更增加了我国气候的复杂多样性。

(1)我国是世界上气候类型最多的国家之一.我国东半部有大范围的季风气候,自南而北有热带季风气候、D亚热带季风气候、C温带季风气候.A西北地区大多为温带大陆性气候。青藏高原区是独特的高原气候。

(2)在中国地图上,把秦岭-淮河线、400毫米年等降水量线和青藏高原边缘线这三条重要的地理界线结合起来,并根据实际情况作一定的调整,就把我国划分为四大地理区域,即北方地区、南方地区、西北地区和青藏地区。其中400毫米等降水量线是A西北地区和C北方地区的分界线。秦岭、淮河主要是我国四大区域中,南方地区与北方地区的分界线;一月份0℃等温线通过的地方;800mm等降水线通过的地方;温度带中,暖温带与亚热带分界线;干湿地区中,湿润区与半湿润区分界线;温带季风气候与亚热带季风

气候分界线等。D南方地区气候区的作物熟制是一年二熟或一年三熟。

The process of recycling paper can help to reduce deforestation and energy consumption on a significant scale. There are many different reasons why we should recycle paper products, and some of these are (26) in the paragraphs below.
