题目内容

【题目】材料:20世纪30年代,田纳西河流域由于森林遭到破坏,水土流失严重,是美国最贫穷落后的地区之一。1933年,美国对流域内的自然资源进行全面的综合开发和管理。经过多年的实践,田纳西河流域的治理已取得了较好的效果。

(1)简述田纳西河流域开发的区位优势。

(2)针对当前长江流域的开发与治理现状,请你就今后长江流域的进一步开发与治理提出合理化建议。

【答案】

(1)(4分)①田纳西河流域处于亚热带湿润气候区,降水丰富,河流流量大,水资源丰富;②流域内地形起伏,河流落差大,蕴藏着丰富的水能资源;③有丰富的煤炭、磷、铅锌矿等矿产资源。(水资源、土地资源、能源丰富等自然条件)

(2)(6分)①进一步加大管理力度,实行全流域的统一管理与开发;②加大对长江水能资源的开发;③疏浚河道,提高流域的通航能力;④进一步改善流域内生态环境;⑤发展特色旅游业。

【解析】

试题分析:

(1)分析流域的开发主要是从流域内水资源、水能资源及流域内矿产资源及土地资源的开发利用等方面进行。田纳西河流域在美国东南部,处于亚热带湿润气候区,降水丰富,河流流量大,水资源丰富;流域内地形起伏,河流落差大,蕴藏着丰富的水能资源;流域内有丰富的煤炭、磷、铅锌矿等矿产资源。

(2)长江流域的开发,借鉴田纳西河流域,进一步加大管理力度,实行全流域的统一管理与开发;长江流域干支流水能资源丰富,要加大对长江水能资源的开发;长江中下游多洪涝灾害,要疏浚河道,提高流域的通航能力;进一步改善流域内生态环境,保护水源及防止水土流失;发展特色旅游业,增加流域内的经济收入。
