西双版纳站2005-2022年生物要素观测数据集

对西双版纳站10个长期观测样地的森林植物群落乔木层每木调查与生物量、森林植物群落乔木层植物种组成及群落特征、森林植物群落灌木层植物种组成及群落特征、森林植物群落草本层植物种组成及群落特征、层间附（寄）生植物物种、森林植物群落凋落物回收量季节动态及回收量、森林植物群落各层优势植物和凋落物的元素含量与能值组成、森林大型野生动物、鸟类种类与数量、森林植物群落乔、灌草本植物物候、森林植物群落乔、灌、草各层叶面积指数观测进行了长期观测，观测数据的采集、质量保证与质量控制均按照 CERN 生态系统长期观测规范开展，可为热带森林生态系统的土壤养分研究、政府生态决策等提供观测数据支撑。

Long-term observations were conducted at 10 permanent sampling plots of the Xishuangbanna Station, including individual-tree surveys and biomass measurements of the arbor layer in forest plant communities, investigations into species composition and community characteristics of the arbor, shrub and herb layers of forest plant communities, documentation of epiphytic (parasitic) plant species in interlayers, analyses of seasonal dynamics and collection quantities of litterfall in forest plant communities, measurements of elemental contents and energetic compositions of dominant plants across each layer of forest plant communities and litterfall, surveys of species and population sizes of large forest wildlife and birds, phenological observations of arbor, shrub and herbaceous plants in forest plant communities, and measurements of leaf area index (LAI) for the arbor, shrub and herb layers of forest plant communities. Data collection, quality assurance and quality control for these observations were all carried out in accordance with the long-term ecosystem observation specifications of the Chinese Ecosystem Research Network (CERN). This dataset can provide observational data support for studies on soil nutrients in tropical forest ecosystems, government ecological decision-making and other related fields.
