Abstract: Since China proposed the construction of the “mountains-rivers-forests-farmlands-lakes-grasslands” community of shared life, the third batch of ecological protection and restoration project has been launched. However, some engineering designs lack integrity, resulting in “true destruction” and “pseudoecology” phenomena. Taking the Shichuan River comprehensive improvement project as an example, this study focused on the environmental problems, including the excavation of river sand and gravel in the Shichuan River, industrial pollution, and the pollution of gas, water and soil caused by the burning of garbage by the nearby villagers. The ecological and living environment continued to deteriorate, and the fish and shrimp gone extinction, polluted water and garbage were widely distributed. The techniques of reconstructing ecological river channels, restoring ecology, reshaping landscape, land leveling, PE composite geomembrane, and soil remediation were applied to construct a community of shared life. We also analyzed the ecological, economic and social benefits. The implementation of the project provided clean soil and stable soil structure for the Shichuan River, effectively improved the environment, enhanced the quality of life, achieved production development and good ecology, and continuously met the needs of social development and construction of beautiful villages. It provided theoretical basis and practical support for constructing the watershed-level community of shared life.
