Community characteristics investigation of Fengshui woods in Eastern Guangdong Province

【Objective】The Hakka geomantic forest community characteristics with regional uniqueness in Shizai Fungshi forest were studied and the scientific values of forest reserves were discussed in order to protect forest utilization， recover local vegetation， and develop forest ecology. 【Method】After plot setting， the characteristics of stone geomantic forests tree layer， shrub layer， and herb layer in the plant community of Jiaoling County in Northern Guangdong Province were investigated； the species diversity index were also determined. 【Result】There were 58 plant species belonging to 35 families and 49 genuses found in Shizai Fungshi forest. Fagaceae， Theaceae， Rubiaceae， Cyperaceae， and Myrtaceae plants were the dominant species in this community since they exhibit clear layer， obvious vertical stratification structure， and clear hierarchy. The plant species together formed subtropical evergreen broad-leaved forest community structure. Therefore， the species richness and diversity index of this plant community was relatively high. 【Conclusion】This forest community displayed high species richness and diversity； as one of the well-preserved natural forests in eastern Guangdong region， the Shizai Fungshi forest featured distinguished typical regional characteristics.
