Use "eco-bags" to build rivers and lakes to protect slopes. Both can grow green plants and are permeable to water. "Eco-bag" is a kind of bag made of polypropylene non-woven fabric. After filling with mud, it forms a structural block, and the blocks are connected with a connecting buckle to replace the cement and stone that were originally used. After such a revetment is built, it is permeable to water, allowing river water and groundwater to flow into each other. The revetment can also grow green plants and beautify the river banks. Coupled with the control of pollutants, rivers and lakes form human, pollutants, plants, microorganisms, animals and other ecological chains to restore the self-purification capabilities of rivers and lakes. Abandoning the cement and concrete of the past, using "eco-bags" to build rivers and lakes, "eco-bags" can grow a variety of green plants.

There are many slopes in China's many rivers and rivers. However, in traditional concepts, slopes are generally built of cement, stone, and concrete. This kind of slope is too hard. Plants can only grow on platforms or on riverside roads. The slopes are bare. “The integrated technology of river and lake slope management and ecological restoration” is to soften the slope, of which the most important one is the “ecological bag”. At present, the technology has been used in many river sections throughout the country and the effect is very good.
