28、程，将黄河水调进青岛市，以解决青岛供水不足的问题。还有比如“引黄入晋”，“引滦入津”等，这几项跨流域调水工程，只能在不同程度上缓解某些城市的缺水问题，还不能从根本上解决北方地区的缺水问题（如黄河的径流量本身就很少）。为了最大程度缓解这种局面，有必要建设更大的工程，这就是南水北调。（活动二）：我们班请了一名小小解说员，下面就请同学们阅读教材第69 页“南水北调”的材料，并请解说员给大家讲解下南水北调的线路，并思考以下问题。、南水北调工程有几条路线？（三条，西线、中线、东线）、哪条线距离最近，解决的是什么地方的缺水问题？（西线，西北地区）、中线方案起点的水库是哪一座？（汉江上游的丹东口水库）、沿京

29、杭大运河的是哪条线？（东线）（小结）：南水北调工程在世界水利史上是罕见的。工程建成后，将把长江、淮河、海河、黄河流域联结起来，构成我国水资源“四横三纵、南北调配、东西互济”的新格局，从根本上扭转中国水资源分布严重不均的局面。2、时间分配不均匀解决对策：兴建水库（过渡提问）：解决水资源时间上分配不均的措施是什么呢？（修建水库）我国有成千上万的水库，洪水期蓄水，枯水期放水，调控水量，提高防洪、抗旱能力、并扩大灌溉面积。简介黄河小浪底水利工程及长江三峡水利工程（图：“中国主要水电站”）学生看图填写 70面的表格。（多媒体展示）水电站河流省区龙羊峡水电站黄河青海省刘家峡水电站黄河甘肃省小浪底水电站黄河
