香根草在流域治理中的应用

Application of vetiver in watershed governance

香根草[Vetiveria zizanioides(L.)Nash]是治理水土流失问题常用的植物,其根系发达,有较强耐受性和涵水固土作用,同时对水体污染物有富集作用。通过分析香根草生态学特性及流域治理存在的问题,探讨香根草技术在流域治理中的作用,以期为流域治理提供思路。

Phytoremediation techniques are commonly used in ecological restoration processes.Vetiver grass has a developed root system,has strong tolerance and functions of retaining water and soil,and plays a significant role in controlling soil and water loss. At the same time,vetiver has an absorption and enrichment effect on pollutants. This article mainly discusses the application of vetiver technology in watershed management based on the ecological characteristics of vetiver grass and the problems in watershed management,with a view to providing ideas for watershed management.
