摘要
"坡改平"生态护坡技术凭借符合绿色发展理念的特征具有很好的发展潜力,为研究其应用效果,采用普查与固定点调查、定性与定量相结合的方法,分析北京示范工程、济南示范工程、延庆试验工程及类比推广工程"坡改平"生态护坡技术的水土保持效果.结果表明:经降雨冲刷及时间推移,"坡改平"生态护坡技术工程完好率、植被成活率及坡面植被覆盖度等指标未减弱,其阶梯状护坡形式不仅增加降雨入渗效果,并能持续增加坡面拦蓄空间和能力.分析结果为生态边坡防护技术在公路、铁路及水利等基础设施建设中应用提供参考.
Abstract
The"Slope Flatten"ecological slope protection technology has great potential for develop-ment due to its characteristics that align with the principles of green development.To assess its applica-tion effectiveness,a combination of census and fixed-point surveys,along with qualitative and quantita-tive methods,was used to analyze the soil and water conservation benefits of the"Slope Flatten"technolo-gy in demonstration projects in Beijing,Jinan,Yanqing pilot projects,and similar promotion projects.The results showed that,indicators such as integrity rate,vegetation survival rate,and slope vegetation cover-age,had not weakened despite rainfall erosion and the passage of time.The stepped slope protection de-sign not only enhanced rainfall infiltration but also continuously increased the capacity to retain runoff.These analysis results provide valuable insights for the application of ecological slope protection technolo-gy in infrastructure projects such as highways,railways,and water conservancy.
