摘　　要：在福建省长汀县河田强度侵蚀山地,探讨了3种不同治理模式对植被物种多样性的影响,结果表明:不同治理模式区的物种多样性均得到不同程度的提高,草灌乔混交治理区的群落植物种类有18科28属31种,补植乔灌治理区的群落植物种类有17科22属25种,老头松改造治理区的群落植物种类有12科14属16种,均比对照区的10科11属11种有较大提高;在不同治理模式对植被物种多样性改良的对比中,草灌乔混交模式效果最好,且草灌乔>补植乔灌>"老头松"改造>对照。In the intensive eroded mountain area of Hetian Township of Changting County in Fujian Province, it was studied the effects of throe different management modes on the species diversity of vegetation. The results showed that the species diversity in the different treatment zones have been improved to varying degrees. There were 31 species of community plants belonging to 28 genera and 18 families in the mixed treatment zone of grass, shrub and arbor, 25 species of eonmmnity plants belonging to 22 genera, 17 families in the treatment zone of replanting arbor and shrub and 16 species of eonmmnity plants belonging to 14 genera, 12 families the in the treatment zone of old pine rehabilitation. The diversity of all these species of eonmmnity plant have been improved greatly comparing with the 11 species of community plants belonging to 11 genera, 10 families in the control area. Among the comparison of different management modes on the improvement of species diversity of vegetation, the mixed mode of grass, shrub and arbor has the best effect. The effects of these modes are listed as mixed mode of grass, shrub and arbor 〉 replanting of arbor and shrub 〉 old pine rehabilitation 〉 control area.
