2012年入冬以来,东北地区(黑龙江、吉林)降水量创1961年以来同期最多纪录2013年4月,黑、吉两省正值耕种时节,却遭受严重的春涝。下图为东北地区示意图。

简述黑、吉两省春涝形成的自然原因并对其农业耕种提出合理建议。

答案

冬季降雪量大,气温低;春季气温回升,积雪大量融化;东北平原地势低平 ,排水不畅。(6分)

利用农田水利工程,加快排水(除雪);加大机械耕播力度,加快耕播进度;

提高农业科技水平,播种早熟品种。(4分)

题目分析:

黑、吉两省位于我国东北地区,读图可以判断,两省的纬度较高,属于温带季风气候区,冬季降雪量大,气温低。春季气温回升,积雪大量融化,融水量大。由图中河流分布判断,两省所在区主要位于东北平原,该区地势低平 ,排水不畅,所以容易形成洪涝灾害。解决洪涝灾害问题的措施,可以利用农田水利工程,加快排水或除雪。加大机械耕播力度,加快耕播进度。提高农业科技水平,播种早熟品种。
