摘要

Vetiver, a plant promoted to help conserve soil and water for farmland by the World Bank in the 1980's, has evolved strongly in the late 1990's to become an important soil bioengineering tool ever since the late 1990's. The benchmark experiments on vetiver root strength in 1996 have played a role toward its wider acceptance. New grounds or harder grounds recently broken into by vetiver include cost-effective stabilization of karst stony slopes in high altitude region and the revegetation of barren quarried face by an in novative patented method by vetiver combined with other ancillary works were conceived and implemented in China. River bank stabilization has been successfully carried out on a major scale in fresh and brackish water environment in the Mekong Delta in Vietnam subjected to waves caused by motorised boat traffic, as well as on the Hanjiang River (a Yangzi River tributary) in China. Trials on the use of vetiver for beach protection were successfully achieved in Senegal and slope stabilization of 100 km length of 18 coastal polders by vetiver was attempted in Bangladesh with varying success. Flume tests were conducted in Australia to throw light on hydraulic characteristics of vetiver in deep flow that will aid in the design of channel stabilization and flood erosion control.
