30年河东,30年河西,河流自有河流的规律;治水不是束水,修堤筑坝不是水利建设的全部;世界性水短缺已成为普遍问题,水危机正逼向人类社会。中国也面临严重的水问题,即水多——洪涝、水少——干旱、水脏——污染。对水问题的关注不只在科技界,政府和公众也表现出日甚一日的忧虑。水是人类赖以生存的必要物质基础,近百年来人口爆炸性的增长,给全球资源和环境都带来了巨大的压力。人类自身生存不仅消耗巨量水资源,而全球气候变化又使水资源利用产生一系列新问题。我国是贫水国之一,水的短缺和水资源合理利用问题相当严重。解决水危机的出路在哪里?如何寻求一条水资源可持续利用的有效途径?近日记者采访了中国科学院水问题联合研究中心副主任、中国科学院长春地理研究所所长邓伟研究员。以下是访谈的主要内容。
30 years of Hedong, 30 years of Hexi, rivers and rivers own laws; water is not a bundle of water, repair embankment dam is not all water conservancy construction; worldwide water shortage has become a common problem, the water crisis is pressing to human society.
