The ecological restoration of the Yangtze River Basin has been an important part of China’s environmental protection work in recent years. This paper proposes ecological engineering mode, land reclamation mode, landscape reconstruction mode, and natural restoration mode of ecological restoration, based on the current situation of abandoned open-pit mines in the Yangtze River Basin (within Jiangsu province) and a large number of practical restoration experiences. The characteristics and applicability of these four Modes are elaborated, providing a reference for the ecological restoration of abandoned mines. An abandoned open-pit mine ecological restoration project along the coast of the Yangtze River in Jiangsu Province was introduced in detail as an example. The main issues in the development of geological disaster risks, the destruction of ecological environment and landscape, and the waste of land resource are identified through the analysis of ecological environmental problems. The ecological restoration of the abandoned mine was carried out successfully following the ecological engineering mode, resulting in good ec ological, social, and economic benefits.
