摘要
植物群落结构与环境的关系可以通过研究植物生活型和生态型进行深入的解析,同时植物生活型是研究植物群落的发生、发展及演替规律的重要内容。中国科学院洞庭湖湿地生态系统观测研究站按中国生态系统研究网络(CERN)监测指标体系,在洞庭湖周期性水文变化情势下,对洞庭湖湿地洲滩典型植物群落类型的物种组成进行长期定位监测。通过专家对洞庭湖湿地3个典型植物群落(苔草、南荻和水蓼)的长期监测数据集进行验证,确保数据的准确性,然后进行分类处理,得到洞庭湖洲滩2011-2015年植物群落植物生活型、生长型和生态型数据集。本数据集包含有植物种名、拉丁名、生活型、生长型、光生态型、水分生态型、土壤pH值生态型、淤积生态型,共8个指标,同时提供了完整的样地信息和样地管理记录,为数据的科学利用提供了空间和时间上的背景信息。本数据集为分析洞庭湖湿地洲滩植被群落生态型和生活型组成,植物群落与环境的相关提供了数据支撑,是深入研究洞庭湖湿地植物被演替的重要参考依据。
Analyzing plant life-forms and ecotypes can provide deep insights into the relationship between plant community structure and environmental conditions,and plant life-forms play an important role in understanding the emergence,development,and succession laws of plant community.An investigation was made on the species life-forms and ecotypes of wetland plants in Dongting lake wetland.In accordance with the unified monitoring specifications of the Chinese Ecosystem Research Network(CERN),the Dongting Lake Wetland Ecosystem Observation and Research Station conducts long-term positioning monitoring on the species composition,species life-forms,growth forms and ecotypes of typical beach vegetation in the wetland ecosystem in response to the changing hydrological conditions of Dongting Lake.The dataset of long-term monitoring conducted on three typical plant communities(Carex sp.,Miscanthus lutarioriparius and Polygonum hydropiper) in Dongting Lake wetland has been verified by experts to ensure the accuracy of the data.We then classified and processed the data to obtain the dataset of community composition of plant life-forms,growth forms and ecotypes on Dongting Lake beach(2011-2015).The dataset covers a total of 8 indicators,namely species name,Latin name,life-form,growth form,ecotype according to light intensity,ecotype according to water requirement,ecotype based on soil pH and ecotype according to responses sediment burial.This dataset comes with detailed background information to ensure its consistency across both spatial and temporal dimensions.This dataset comes with detailed background information about site information and site management records to ensure its consistency across both spatial and temporal dimensions.This dataset can provide support for the analysis of the classification of plant life forms and the composition and structure of ecotypes,and serve as valuable reference for further study of vegetation succession in Dongting Lake wetland.
