水资源短缺现象原因及解决办法

水资源短缺21世纪,水,已成为世界各国关注的焦点。

水资源短缺、水资源分布不均、水环境被严重污染等等都是当今社会所急需解决的一系列问题,这些问题对世界各国的经济发展已构成了重大的威胁,如何解决好水多、水少、水脏和水污染等问题直接关系到水资源的可持续利用、粮食生产的安全、经济增长方式、国民经济的可持续发展、维持生态环境的安全以及国内国际环境的安定。

水,是经济,也是挑战。

通过一个学期的学习,对于《环境概论》这门课程也有了一定的认识,对于水资源短缺这一问题可以主要从以下几个方面分析:一、水资源短缺的当前现状根据当前形势,全球水资源短缺本就已存在的情况大致可以分为以下几种情况:1、淡水资源是十分有限的资源。

在全球水资源中陆地淡水仅占6%,其余94 为海洋水。

而在陆地淡水中,又有77.2%分布在南北极,22.4%分布在很难开发的地下深处,仅有0.4 %的淡水可供人类维持生命。

2、淡水资源的分布极不均衡,导致一些国家和地区严重缺水。

如非洲扎伊尔河的水量占整个大陆再生水量的30%,但该河主要流经人口稀少的地区,造成一些人口众多的地区严重缺水。

再如美洲的亚马逊河,其径流量占南美总径流量的60%,但它也没有流经人口密集的地区,其丰富的水资源无法被充分利用。

俄罗斯和中亚地区也面临类似的情况,丰富的水资源流经西伯利亚注入北冰洋,而人口众多的西部、南部、中亚地区则出现水资源短缺。

全球水资源分布在地理上已经基本确定,难以重新分配。

巴西、俄罗斯、中国、加拿大、印度尼西亚、美国、印度、哥伦比亚以及扎伊尔9 个国家拥有了全球水资源的60%,即便在一定范围进行重新分配,其成本也是极高的。

3、水是难以替代的资源。

人类要找到一种理想的水替代品,要比寻找石油和木材等资源的替代品困难得多,尽管许多缺水国家已经开始海水淡化工作,但目前在资金和技术上都还远远无法解决水资源短缺问题。

除了以上的情况还有其他一些因素加剧了全球性的水资源危机:I.人口的增长使淡水供应紧张。
