Abstract
The protocol of Landscape Function Analysis (LFA) has been utilised to assess rehabilitated mine sites by observing 11 key factors of soil surface condition that range from soil cover to soil texture (Tongway and Hindley, 1995). Individual transect of 50-m long was established at revegetation sites and undisturbed forest respectively. Recent results from two mine sites (coal mine sites at PT Tambang Batubara Bukit Asam, Tanjung Enim) and ex-tin mine site of PT Kobatin in Central Bangka demonstrated the potential use of this protocol. Soil recovery is indicated by increasing aggregate stability from 30 % to about 60 %. The values of individual LFA indices (stability, infiltration and nutrient cycling index) vary by up to 10 % between the sites, which reflects characteristics of the dominant surface zones for the whole landscape. Patch area index (PAI) increased steadily with age of revegetation to nearly 60 % which is close to the value for forest. The infiltration (mean 34 %) and nutrient cycling indices (mean 27 %) for the revegetation sites are considerably lower than values for the forest site (infiltration 55 %, NCI 48 %) largely due to differences in litter abundance and vegetation cover.
