| 摘 要： | 根据国内外先进的河道护岸技术，并结合重庆市桃花溪的立地条件在该河道岸坡开展示范区，以河岸生物多样性和岸坡稳定性为目的的河道护岸技术研究。在示范区各观测带采用了抛石结合植物扦插、自然原型护岸、土工织物扁袋结合扦插、天然材料织物垫4类护坡技术，并植入土壤生物工程的理念，对4种模式下的岸坡进行连续两年的生态监测，研究护坡工程的水土保持功能。经过整治，岸坡的植物种类明显增加，生物多样性更加丰富，植物群落由单一结构向复杂结构转变，坡面的抗剪强度也大幅提高，岸坡稳定性增强。

| Abstract: | Based on the advanced ecological protection technique both at home and abroad, and combined with the site conditions of Taohua river in Chongqing city all demonstration plots were developed, and the research about ecological slope protection techniques for biodiversity and stability of riverbank were carried out. This study investigated the application of four ecological slope protection techniques combined with soil bioengineering including riprap integrating with plant cutting, crude revetment, geotextile flat bag (geotextile flat bag can select and use sacking), natural materials fabric pad in all observed terrain of demonstration plot. In order to study soil and water conservation benefit of the slope protection project, the four ecological slope protection techniques were conducted for continuous ecological monitoring during two years. After regulation, plant species and biodiversity increased obviously, and the structure of phytocenosis varies from simplicity to complexity. The stability of eco-riverbanks is being enhanced due to increasing the shear strength of riverbank. |
