[Objective] The advancement and practicality of wet-spraying vegetation-compatible concrete (VCC) were studied to provide a reference for ecological protection of engineering slopes.[Methods] The application of the new technology in the slope protection of a channel connected to Huama Lake in Ezhou City

Hubei Province

was presented. The effects of slope protection and soil and water conservation were observed. Furthermore

the plant coverage

plant density

average plant height

and species diversity index were tested on site.[Results] The technology could keep the slopes remained stable. The VCC substrate could adhere well to the slope surface

without forming gullies and slumps

with good soil and water conservation. The fundamental contradiction between the spraying of the VCC substrate and its adhesion to the slope surface was successfully solved. One month after the construction

the overall vegetation coverage of the slope reached more than 90%. The Shannon-Wiener diversity index

the Pielou evenness index

and the Simpson dominance index of the vegetation in the gentle-slope area were similar to those in the steep-slope area

but there were differences from the natural slope. The overall cost of the new technology (wet-spraying version) was 5%~15% lower than that of the old one (dry-spraying version).[Conclusion] As an upgraded version of dry-spraying VCC

this new technology shows significant advancements and can be used for ecological protection of engineering slopes.
