解题思路：环渤海经济圈是我国北方经济最活跃的地区，属于东北、华北、华东的接合部，改革开放以来，环渤海已经形成了发达便捷的交通优势，雄厚的工业基础和科技教育优势，丰富的自然资源优势，密集的骨干城市群等五大优势．制约环渤海经济圈经济发展的资源条件是水资源短缺．

（1）读图可知，图中E是太行山脉，威海临黄海．
（2）图中威海市与纬度相当的济南相比较，气温年较差较小的是威海，因为威海位于沿海地区，冬季温和，夏季凉爽，温差较小；济南位于内陆，温差较大．
（3）制约环渤海地区经济发展的限制性因素是水资源短缺，解决的措施是南水北调．
（4）环渤海地区经济发展的优势条件是矿产资源丰富，交通便利，科技发达等．
（5）F处位于淮河以北，耕地类型是旱地，地形平坦，在农业部门来看，应该适宜发展种植业．
故答案为：（1）太行；黄；（2）威海；威海位于沿海地区，冬季温和，夏季凉爽，温差较小；济南位于内陆，温差较大；（3）水资源短缺；南水北调；（3）矿产资源丰富，交通便利，科技发达等；（5）旱地；种植业．
