读某大陆沿海地区等高线及等深线图,回答题。

小题1:当地欲建一港口,以此作为启动该地区经济发展的钥匙,港口最宜建在图中:

A.①地

B.②地

C.③地

D.④地小题2:该地区某小镇周边地形状况如右图,图中两条小河的流量相当。进入小镇的引水线最合理的是

A.① 

B.②

C.③ 

D.④

答案

小题1:B

小题2:D

小题1:题目分析:港口建设应考虑陆域和水域两方面条件,水域条件考虑应建于海湾地区,可避风浪;等深线较密集,则水深利于建港口;从陆域考虑,应布局于陆上地域平坦开阔地带,适宜建港。比较图示四地,①地等深线分布稀疏,水浅;③地位于岛上,地域面积狭小,且地形起伏大;④地水浅。故②地最适宜。

点评:本题难度一般,解题的关键是掌握影响港口建设的水域和陆域条件的综合因素,并能结合图示的海陆分布和等高线、等深线分布判断。

小题2:题目分析:引水线建设应考虑地势条件,从高处向低处引水可自流,并考虑线路长短,减少工程量。注意河流流向与等高线凸向的相反,可判断河流的流向。故比较四条线路,④线路最合理。

点评:本题难度一般,掌握引水线建设的主要影响因素和利用河流与等高线凸向的关系判断地势高低是解题的关键。对于此类试题,学生应在平时的学习中加强一般规律的总结和归纳。
