Our aims were to describe the role of the selective management of regenerating community (RC) on the recovery of ecosystem functions in production areas of African mahoganies under mixed stands and agroforestry systems, established on abandoned farmland. A randomized block experiment was set up with the following treatments: (T1) mixed-plantation of African mahogany under conventional system (including herbicide application); (T2) mixed-plantation of African mahogany with selective conduction of RC; (T3) agroforestry system with African mahogany; (T4) agroforestry system with African mahogany with selective conduction of RC. The parameters of horizontal structure, diversity and ecological attributes of species of the regenerating community were studied. In addition, the production of aboveground biomass and nutrient stocks, soil fertility, and soil microbial activity were assessed. In T1, herbicide application (glyphosate) affected the floristic composition of the regenerating community by reducing the dominance of monocots and Pteridium arachnoideum, allowing the regeneration of other taxonomic groups of herbaceous species. In response, there was a reduction in the litter biomass stock comparing to the other treatments. The treatments with selective management of the RC (T2 and T4) produced more biomass and accumulated higher amounts of C and nutrients than the conventional treatments (T1 and T3). These treatments also allowed other shrub and tree species to overcome the ecological filter imposed by grasses and colonize the experimental area. Baccharis dracunculifolia, Vismia guianensis, Cecropia pachystachya and Inga sp. were the most important regenerating species that contributed most to the stocks of all nutrients in living aboveground biomass. Pruning and selective management in T4 increased the soil effective cation exchange, while in the T1 treatment there was a lower activity of the β-glucosidase enzyme. The selective management of RC in agroforestry systems through the manipulation of competitive relationships allowed the colonization of native tree and shrubby species that provide several additional ecosystem services, including pollination, fauna attraction, food production, pest control and environmental regulation for the agroecosystem.

我们的目的是描述再生社区（RC）的选择性管理对非洲桃花心木生产区在废弃农田上建立的混交林和农林业系统恢复生态系统功能的作用。建立了以下处理的随机分组试验：（T1）在常规系统下（包括除草剂施用）混合种植非洲红木；（T2）非洲红木的混植与RC的选择性传导；（T3）非洲桃花心木的农林业系统；（T4）非洲桃花心木农林系统，选择性传导RC。研究了再生群落物种的水平结构，多样性和生态属性。此外，地上生物量和养分储量的生产，土壤肥力，评估土壤微生物活性。在T1中，除草剂的应用（草甘膦）通过降低单子叶植物和单子叶植物的优势影响了再生群落的植物组成。蕨类植物，可以再生其他种类的草本物种。作为响应，与其他处理相比，垫料生物量的减少。与常规处理（T1和T3）相比，对RC进行选择性管理的处理（T2和T4）产生更多的生物量，并积累了更多的碳和养分。这些处理方法还使其他灌木和树木物种能够克服草所强加的生态过滤条件，并将其定居在实验区域。Baccharis dracunculifolia，Vismia guianensis，Cecropia pachystachya和Ingasp。是最重要的再生物种，对生活在地下的生物质中所有营养成分的贡献最大。T4中的修剪和选择性处理增加了土壤有效的阳离子交换，而在T1处理中，β-葡萄糖苷酶的活性较低。通过竞争关系的操纵对农林系统中的RC进行选择性管理，使本地树木和灌木物种得以定殖，从而提供了多种生态系统服务，包括授粉，动植物吸引，粮食生产，病虫害防治和农业生态系统的环境调节。
