比较了哥伦比亚中部安第斯山脉（2000 m）21年生的巴西松（Pinus patula）和墨西哥柏（Cupressus lusitanica）人工林与成熟低山地雨林（LMRF）的物种丰富度、多样性和土壤理化性质。在0.1ha样地中，物种丰富度（物种数）和多样性（Shannon和Simpson指数）以LMRF最高，其次是P. patula和C. lusitanica种植园结果表明：人工林中高等植物有30科56种，展花杨人工种植园有15科26种，杜鹃花有10科18种。lusitanica种植园在土壤理化性质上，大花杨、毛白杨和毛白杨之间差异不显著（p<0.05）。lusitanica和本地LMRF。然而，土壤碳，C/N比和总基地往往是在天然林高于人工林。有效磷在展叶松种植园中有较高的趋势。这些结果表明，虽然废弃的人工林可以支持一些本地物种，特别是在林下，物种丰富度是远离原生林。
Species richness and diversity and soil physical and chemical properties were compared between a mature lower montane rain forest (LMRF) and abandoned 21-year-old plantations of introduced Pinus patula and Cupressus lusitanica in the central Andes of Colombia (2000m). In 0.1ha plots, species richness (number of species) and diversity (Shannon and Simpson indexes) were higher in the LMRF, followed by P. patula and C. lusitanica plantations. There were 56species and 30families of higher plants in the LMRF, 26species and 15families in the P. patula plantation, and 18species and 10families in the C. lusitanica plantation. There were no statistically significant differences (p<0.05) in soil physical or chemical properties between P. patula, C. lusitanica and native LMRF. Nevertheless, soil carbon, the C/N ratio and total bases tended to be higher in the native forest than in the plantations. Available P tended to be higher in the P. patula plantation. These results show that, although abandoned plantations can support some native species, particularly in the understorey, species richness is far from that of the native forest.
