Abstract: Soil characteristics of 5 different successional types of vegetation in Chebaling National Nature Reserve, Guangdong Province were investigated. The preliminary results showed that the soil characteristics varied greatly with different sites. In general, the intact forest possessed higher content of organic matters, total nitrogen, available phosphorus and available potassium. As compared with the other broadleaved forest, the secondary grassland dominated by Miscanthus floridulus and Imperata cylindrica were lower in available phosphorus and total nitrogen, but higher in available potassium and pH value. The pine woodland were lower in organic matters and available potassium, but higher in available phosphorus than other vegetational types.
