摘要:

西南山地人工林作为长江上游生态屏障的重要组成部分, 对于维持我国西部生态安全, 促进区域可持续发展发挥着关键作用。植物物种组成与群落特征是研究森林生态系统结构和功能的重要指标, 对于评估人工林群落结构、演替动态、生态系统健康的可持续管理具有重要意义。在中国科学院茂县山地生态系统定位研究站, 于2005、2007和2010年, 对50 m × 50 m典型华山松(Pinus armandii)人工林固定样地进行调查。该数据集整理了该样地乔木层、灌木层、草本层和层间藤本植物的物种组成特征, 包括株数、平均胸径(灌木为平均基径)、平均高度、盖度和生活型; 以及各层的群落特征, 包括优势种、植物种数、密度等。在5年内, 样地内物种数量随着演替进程而增加, 增加物种主要为乡土物种。乔木层密度迅速降低, 归因于栽培树种的高死亡率(20%), 灌木层密度降低是因为乔木层遮阴增强导致大量灌木死亡, 以及乡土物种幼树由灌木层进入乔木层。该数据集可为西南山地人工林植被恢复、群落演替规律、生态系统可持续管理等研究提供数据支撑。

Abstract:

Montane coniferous plantations in southwest China serve as a crucial ecological barrier of the upper reaches of the Yangtze River, fulfilling multiple ecological service functions including soil and water conservation and maintenance of biodiversity. Therefore, these plantations play a key role in maintaining regional ecological security and promoting sustainable development in western China. Plant species composition and community characteristics are critical indicators for studying the structure and functioning of forest ecosystems, and are vital for observation and assessing the dynamics of community succession, biodiversity, ecosystem health and sustainability. We have conducted three community surveys in a 50 m × 50 m permanent plot of montane coniferous plantation in 2005, 2007 and 2010 at the Maoxian Mountain Ecosystem Observation and Research Station of the Chinese Academy of Sciences. The dataset provided detailed information on plant species composition and community characteristics of tree layer, bush layer, herb layer and interlayer vines. Species names, scientific names, individual number, average diameter at breast/basal height, average height, coverage and life form were recorded. Community characteristics included dominant species, density, average height of dominant species and coverage were recorded. Species number (mainly native plants) increased with community succession. However, density in tree and bush layers decreased, caused by the high mortality rate of planted bush trees due to insufficient sunlight under the forest, and native saplings entering into tree layer. The dataset would provide empirical support for studies and practices of vegetation restoration, community succession and sustainable management of montane coniferous plantations in southwest China.
