黄河水利枢纽对生态环境的影响

黄河水利枢纽工程在调节水量丰枯，改善干旱与半干旱地区生态状况以及调节生态用水等方面作用巨大。但工程也改变了河流自身的形态，降低了河流形态多样性。客观地评价黄河水利工程建设对流域经济、社会、环境发展的得失，提醒人们对水利工程的工程理念进行反思。水利枢纽工程在满足社会需求的同时，兼顾生态系统的健康和可持续性，促进人与自然的和谐共存。

Influence of water control project on Yellow River to ecological environment

The water control projects on the Yellow River have played a great role on the regulation of water during the wet and dry years, and improved ecological condition in the arid and semi arid regions as well as the regulation of ecological water consumption. However, the project has also changed the river pattern itself, and reduced the diversity of river condition. From the practical point of view to evaluate the gains and losses of water control projects on the Yellow River to the development of economy, safety and environment, it reminds the people to have a reflection on the engineering concept of water control projects. The water control project not only satisfies the demand of the society, but also maintains the health of ecological system and sustainability, promotes harmonious coexistence of human being and nature.
