水利工程是人类通过人工建造建筑物,对自然水体进行开发利用、调配及治理,从而实现除害兴利目的的科学。但是,在水利工程的发展初期,由于人们对自然规律认识的局限性,往往只注重人类水利工程对人类社会需求的满足,而忽视了对自然环境的保护,致使早期的许多水利工程都存在影响水体健康的问题,引发了各种环境问题。所以,人们在开发水环境资源时,应兼顾生态效益和经济效益。 Water conservancy projects are the science of mankind’s goal of building a well-off society by artificially building buildings and developing, utilizing, allocating and controlling natural water bodies.
