Abstract

Evidence of environmental changes in Hong Kong, including vegetation, climate and the frequency of hillfires is presented. Field observations made in the Northwest New Territories provide evidence that hillfires increase soil erosion on slopes and result in higher storm-period concentrations of suspended sediment. Monitoring carried out in a small drainage basin reveals that lanslides deliver sediment in an upland stream giving very high concentrations and affecting sediment properties, with the C and N content declining under the influence of landslides
