问题 综合

阅读下列材料,回答下列问题

材料一:田纳西河流域早年由于水土流失、洪涝频繁、人口稀少等原因,导致经济水平低。

材料二:位于金沙江下游的向家坝水电站于2006年11月26日开工。长江干流上游宜宾(四川)以上称金沙江,流经青、藏、川、滇四省区,水能资源丰富,富集程度堪称世界之最。

小题1:借鉴田纳西河流域的水电开发经验,金沙江水能开发也采取梯级开发的形式,试分析金沙江水能资源丰富的原因?

小题2:向家坝电站建成后,中国政府计划在此地密集投建炼铝和化学等重工业区,试分析原因?

小题3:从生态角度简要分析金沙江水能开发中要注意的问题。

答案

小题1:降水量大,河流水量大;地势起伏大,河流落差大。

小题2:炼铝和化学等工业均为高能耗工业;电力充足;矿产资源丰富

小题3:要重视环境保护、生态建设,植树造林、保护植被,防止水土流失等。

考查流域的地理特征。

小题1:金沙江位于长江上游,河流落差大;加之季风气候区,降水量大,河流水量大。因此蕴藏丰富的水能资源。

小题2:炼铝和化学等工业均为高能耗工业,向家坝电站建成后,可以为其提供充足的电能;加之此地有色金属矿产丰富,有充足的原料。

小题3:金沙江位于长江上游,对其水能开发要注意:重视环境保护、生态建设,植树造林、保护植被,防止水土流失,减少对中下游的影响。
