| 摘 要： | 应用香根草生态工程对广州市一环路天鹿湖路段的2个滑坡面进行护坡治理。结果表明，香根草生态工程的护坡效益是非常明显的。在生态效益方面，实施工程半年就能产生明显的护坡效果，4年后，生物多样性大幅度增加，土壤水分与养分含量都不同程度升高，并明显改善公路两边的生态环境；而且实施香根草生态工程为公路护坡节省了大笔经费。总的来看，香根草生态工程在我国南方地区应用于公路护坡的前景是十分广阔的。

| Abstract: | The vetiver eco engineering was applied in South China for the first time to control landslides and protect highways. The results showed that vetiver planted in slopes of highways under appropriate cultivation and management measures, grew rapidly and luxuriantly and formed dense hedgerows. It was quite effective for stabilization of slopes and soil moisture and nutrients. Furthermore, it did cost only about one sixteenth of the stone based technique. In a word, application of the vetiver eco engineering in roadbed and embankment protection can produce quite good ecological, social and economic benefits, which indicates that the engineering will have a broad application perspective. |
