Research on Ecological Restoration Technology of Urban Waterfront——Qinhuai River as an Example

Effect of rivers on the human cannot be ignored, in general, the river corridor has the rich vegetation can control the dissolved material from the landscape matrix. It provides enough habitat and channel for inside species on both sides of rivers and reduces dissolved pollution from the surrounding landscape to ensure water quality, environmental purification, climate change, and it also can slow down the flood. With the development of urban, the demand for riparian zone began to rise. During some reconstruction project, the vegetation revetment technology has become more popula

Performance Evaluation and Field Application of Porous Vegetation Concrete Made with By-Product Materials for Ecological Restoration Projects

The purpose of this study was to evaluate the performance of porous vegetation concrete block made from blast furnace slag cement containing industrial by-products such as blast furnace slag aggregate and powder. The blocks were tested for void ratio, compressive strength and freeze-thaw resistance to determine the optimal mixing ratio for the porous vegetation block. An economic analysis of the mixing ratio showed that the economic efficiency increased when blast furnace slag aggregate and cement were used. Porous vegetation concrete blocks for river applications were designed and produced. Hydraulic safety, heavy metal elution and vegetation tests were completed after the blocks were applied in the field. The measured tractive force ranged between 7.0 kg/m2 for fascine revetment (vegetation revetment) and 16.0 kg/m2 for stone pitching (hard revetment), which ensured sufficient hydraulic stability in the field. Plant growth was measured after the porous vegetation concrete block was placed in the field. Seeds began to sprout one week after seeding; after six weeks, the plant length exceeded 300 mm. The average coverage ratio reached as high as 90% after six weeks of vegetation. These results clearly indicated that the porous vegetation concrete block was suitable for environmental restoration projects
