黄河流域水循环演变若干问题的研究

从若干方面的研究结果揭示了黄河流域水循环发生的巨大变化.水循环是水资源科学评价与合理开发利用的基本依据.水循环主要要素的变化取决于气候条件的变化与人类活动的影响.对前者宜采用适应性对策,在研究气候变化的基础上,分析水循环变动的规律并预测其趋势,制定相应的适应性措施;对于后者则应加强水资源开发利用的科学管理,以维持流域天然水资源的可更新(可再生)性.

Study of some problems in water cycle changes of the Yellow River basin

This paper deals with water cycle and identifies its remarkable changes in the Yellow River basin. The water cycle provides an essential foundation for scientific assessment and rational development of regional water resources. The changes of water cycle elements depend closely on climate variations and human activity impacts. Based on the careful investigations of the influences resulting from climate change and human activities, the author describes the water cycle changes in the Yellow River basin, and suggests in this paper that the adoptive measures should be employed to adopt climate change influence through deeper and better understanding of the relationship between water cycle and climate change trend and predict it. The human activity impacts could scientifically controlling water resources development by enhancing water management. All in all, the targets should maintain renewability of natural water resources system in the Yellow River basin.
