- Abstract:

A comparative study was conducted on the plant biodiversity of tree layer, shrub and herb layers in eucalypt plantation (the second-generation and the first-generation) and conifer-broadleaved forest (10-11 years old and 5-7 years old) in southern subtropical region to understand the effects of eucalypt plantation and conifer-broadleaved forest on the plant biodiversity by using the methods of site condition control and space instead of time. The present results showed that there were 68 species belonging to 38 families and 62 genera in conifer-broadleaved forest (10-11 years old), and 41 species belonging to 26 families and 39 genera in eucalypt plantationⅡ (the second-generation of eucalypt), 53 kinds of plants, belonging to 30 families and 48 genera in conifer-broadleaved forest Ⅲ (5-7 years old), and 55 species belonging to 33 families genera 51 in eucalypt plantation Ⅳ(the first-generation of eucalypt). The large important values of families of tree layer were Taxodiaceae, Lauraeeae, Hamamelidaeeae, Euphorbiaceae, Theaceae, Magnoliaceae and Meliaceae, those of shrubs were Araliacea, Euphorbiaceae, and those of herb layer were Graminaceous, Lindsaeaceae and Blechnacea in conifer-broadleaved forest. The large important values of families of tree layer were Myrtaceae, Rutaceae, Lauraeeae, Euphorbiaceae, Anacardiaceae, and those of shrubs were Aquifoliaceae, Lauraeeae, Euphorbiaceae, Rutaceae, and those of herb layer were Graminaceous and Gleicheniaceae in eucalypt plantation. The species richness (S), Shannon-Wiener index (H’), Simpson dominance index (D), Pielou evenness index (E) of tree layer, shrub layer and herb layer were not significant (P > 0.05) among four kinds of experimental forests. The index of H’, D and E of tree layer and shrub were significantly higher than those of herb layer (P < 0.05), the index of H’, D and E were significantly different (P < 0.05) among tree layer, shrub and herb layer in eucalypt plantationⅡ. The evenness index (E) of conifer-broadleaved forest was greater than that of eucalyptus forest. The index of S, H’, D and E of tree layer in conifer-broadleaved forestⅠincreased, while those of the shrub and herb layers decreased compared with the conifer-broadleaved forestⅢ. The indexes of S, H’ and D of shrub and herb layer in eucalypt plantationⅡ(the second-generation of eucalypt) declined in varying degrees compared with the eucalypt plantation Ⅳ(the first-generation of eucalypt). The results provided a scientific basis for species diversity conservation and sustainable management of eucalypt plantation.
