Structural characteristics of the secondary-evergreen broadleaved forest in Dapingzhang Forest Park

The secondary-evergreen broadleaved forest was surveyed by using point-quarter sampling method in Dapingzhang Forest Park, Dongguan. The least sampling point in this type of forest was determined. Twenty sampling points were clustered into four types. The dominant species and the ecological physiognomy and community structure of evergreen broadleaved forests were analyzed. The forest was dominated by Cyclobalanopsis myrsinaefolia and Cratoxylum cochinchinense, with an evergreen physiognomy. This community lacked large buttresses and wood megalianas. But epiphytes are rich, demonstrating some features of the south subtropical monsoon evergreen broadleaved forest. Structure of this community is simple, and it can be divided into three layers, namely tree , shrub and herb layers. The secondary-evergreen broadleaved forest was important to the development of Dapingzhang. The protection of such forest must be strengthened to facilitate its succession.
