【摘要】 水是生命赖以存在的重要资源。基于水文循环规律,使有限水量得以循环往复。由于人类社会对淡水资源与日俱增的迅猛耗用等诸多原因,三水循环障碍,严重危及地球水资源固有的可更新性,使旱区范围扩大、旱情加剧的趋势明显呈现。对此,寻求共识以未雨绸缪,并藉助于科学技术进步,促进水文循环,开源节流,抗御干旱,应成为当今世界紧迫的共同问题。

【Abstract】 Water is an important resource on which life depends for its existence.Based on the laws of hydrological cycle ,the limiting water resources can cycle and cy-cle. Owing to an increasing demand for fresh water resources and fast consumption byhuman beings,the blockage of fresh water cycle seriously threatens the renewability ofwater resources on the earth.As a result,the arid areas continue to expand so fast thatthe worsening of drought trends become more and more aparent.For this reason ,it isnecessary to seek for the common understanding with saving against a rainy day,and topromote the hydrological cycle and the development of resources in an economic way bymeans of progress in science and technology so as to fight against droughts. This can bethe urgent probiem of common nature in today’s world.
