以宁化县紫色土侵蚀区4种主要治理模式的植物群落调查资料为基础，采用丰富度指数、均匀度指数和多样性指数对其进行分析。研究结果表明：1）与对照区相比，各治理样地植物群落物种多样性、丰富度和均匀度指数均有不同程度提高，植物群落结构趋于复杂稳定。2）随着演替的进展，群落多样性指数在乔灌草混交及封禁治理模式增大，但在油茶园改造模式中变化不明显。3）经济林模式治理年限短，受人为干扰强烈，植物多样性差异较大，其随治理年限的变化有待于进一步观察。4）植物多样性与植物生长型的关系：物种丰富度和多样性指数在治理初期为草本层大于灌木层，随着群落演替的进展，灌木层逐渐大于草本层；均匀度指数的变化，在油茶园改造及乔灌草混交模式中草本层大于灌木层，而在经济林和封禁模式中，多表现为灌木层大于草本层。因此，后续治理应注意：侵蚀劣地的生态恢复必须进行科学的人为干预，生物措施应合理配置乔灌草物种数和个体数，对树种单一的群落需进行补植修复；针对不同治理阶段和治理模式，生态恢复侧重点要有差异。

According to plant community survey data in four governance modes, the plant diversity was analyzed with richness index, evenness index and diversity index.The results show that:1) Com-pared with the control area, the plant species diversity index in the plots improved to varying degrees, plant communities become more complex and stable in structure;2 ) With the progress of community succession, species diversity indices of communities in the Camellia transformation mode did not change significantly, but increased sharply for the mixed mode of tree, shrub and grass, as well as in banned mode; 3) In the forest mode, because of short treatment time and intense human disturbance, there was a large differences in species diversity index among the plots, and the changes over govern-ance time were not clear;4) The link between plant diversity and plant growth was:the richness and diversity index of herb layer species was higher than shrub layer at the beginning, with the increase of management time, that of shrub layer was better than the herbaceous layer;the evenness index of her-baceous layer was better than the shrub layer in Camellia transformation mode, as well as in the mixed mode of tree, shrub and grass, but in the forest and banned mode, there was opposite phenomenon. Therefore , we believe that the eco-restoration of eroded lands must be treated with reasonable interven-tion, the species number and individuals of tree, shrub and grass should be rational allocated in bio-logical measures, tree structure need to be adjusted for single species communities; At different gov-ernance modes and different stages, the focus of the ecological restoration should be differences.
