Abstract

Evidence of environmental change in Hong Kong, including vegetation, climate and the frequency of hillfires is presented. Hillfires may be an important influence upon slope degradation in the territory. 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 landslides deliver sediment to an upland stream giving very high concentrations and affecting sediment properties, with the C and N content declining under the influence of landslides. Should environmental change alter the frequency of landsliding and hillfire on natural terrain in Hong Kong this will have implications for hillslope degradation and sediment transport in upland streams.
