利用森林资源清查资料，研究了演替多样性与森林生态系统功能的关系。清查数据表明，林分组成的早期演替的物种比林分组成的晚期演替的物种更有生产力，而林分组成的晚期演替的物种有较低的营业额比林分组成的早期演替的物种。单独来看，这些结果表明，森林的管理方式应该有利于生产力最高的早期演替物种或寿命最长的晚期演替物种，这取决于目标是最大限度地提高生产力还是最大限度地提高碳储存。然而，清单数据也表明，低演替多样性的林分固定和储存的碳比高演替多样性的林分少。这一结果表明，森林的管理方式应保持物种多样性，同时也有利于最大限度地发挥生态系统功能的物种。
Forest inventory data was used to examine the relationship between successional diversity and forest ecosytem function. The inventory data show that stands composed of early successional species are more productive than stands composed of late successional species, whereas stands composed of late successsional species have lower turnover than stands composed of early successional species. Taken alone, these results would Suggest that forests should be managed in a way that favors the most productive early successional species or longest-lived late successional species, depending on whether the goal is to maximize productivity or maximize carbon storage. However, the inventory data also show that stands with low successional diversity fix and store less carbon than stands with high successional diversity. This result suggests that forests should be managed in such a way as to retain species diversity while also favoring species that maximize the ecosystem function of interest.
