Ecosystem degeneration always results in the descend of human life-depended goods supply and ecosystem services, which in turn inhibits the development of economy and society. Taking the abandoned delta of Huanghe River as a case, this paper analyzed the natural and artificial driving forces of ecosystem degeneration, with the degeneration course investigated. Based on the present status of the ecosystems in the delta, the goal of ecological restoration and related countermeasures were put forward, including remedying water ecosystem and enhancing biodiversity by natural restoration and human control, and promoting harmonious development of ecology and economy.
