从对黄河流域70多年气象、水文等资料的分析入手,阐明了气候变迁、引水灌溉及水利、水土保持工程等因素对黄河水沙变化特征的影响。进而指出,当今黄河的水沙状况除受自然因素制约外,已在很大程度上为社会、经济等人为因素所影响。
Beginning with the analysis of the meteorological and hydrological data in the Yellow River Basin for more than 70 years, the author has clarified the influence of climate change, diversion irrigation, water conservancy and soil and water conservation projects on the characteristics of water and sediment changes in the Yellow River. Furthermore, it is pointed out that besides the natural factors, the water and sediment status of the Yellow River has largely been affected by human factors such as social and economic factors.
