全球变化与水文科学新的进展与挑战

HYDROLOGICAL SCIENCE TOWARDS GLOBAL CHANGE: PROGRESS AND CHALLENGE

该文是作者应邀参加 2 0 0 1年 7月 1 0日～ 1 3日在荷兰阿姆斯特丹举行的国际地圈生物圈计划(IGBP)的全球变化科学大会和 7月 1 8日～ 2 7日在荷兰马丝特里特举行的第 6届国际水文科学大会的报告总结。前一个大会的主题是“变化环境下的挑战” ,后者的主题是“干旱地球的新水文学”。该文综合了两个大会的主要议题 ,反映出当前水文学科的发展方向主要在于研究变化环境下的水循环时空演变规律以及不同尺度水循环物理过程间的联系影响。全文主要内容有 :全球变化与水文科学问题 ,水文科学发展与水资源安全 ,2 1世纪水文科学的发展机遇与展望。目的是介绍国际水科学研究新的动向、热点问题 。

Having been invited to the Global Change Opening Science Conference and the 6 th Scientific Assembly of the International Association of Hydrological Science, the authors outline progresses and challenges confronted by hydrological science in the new century, which have been presented in the above-mentioned conferences. Main subjects suggested as key points in the future are as follows: global change and scientific issues of hydrology, development of hydrological sciences and water resources safety, prospect and opportunity of hydrological science in the 21 st century. It is argued that, by employing the new research directions and hot issues within the international hydrological science, chinese researchers can launch out more basic researches of water resources and those oriented towards nation's needs.
