Based on the principles of ecology and design, the general method framework of designed ecosystem was put forward. The framework is guided by the provision of integrated ecosystem services and based on the basic laws of the ecosystem, which aims to create a balanced habitat of soil and water, configure a stable and orderly local biological network, and design recreation facilities with minimum intervention. At the same time, according to the practice of ecological restoration design and the classical ecological engineering design guides, this study summarized the key design parameters of the designed ecosystem from three aspects: structure, materials and auxiliary measures, a total of 31 items. On this basis, to engineer the traditional ecological wisdom, specific design methods and quantitative parameters of terrace, impounding-pond, dike-pond and stacking-fields habitat creation modes in the aspects of basic model characteristics, habitat unit shaping, water cycle regulation, soil environment regulation, biological community allocation and recreation facilities construction were put forward. This result provides an engineering and replicable method for the practice of large area ecosystem restoration engineering in China.
