Ecosystem functions and vegetation data for Winklebury Hill, Salisbury Plain, UK 2016

This dataset contains vegetation survey data, and nitrate and ammonium concentrations, nitrification and mineralisation rates, microbial biomass and carbon and nitrogen stock data from soils taken from an experiment based at Winklebury Hill, UK. The vegetation survey comprises total species percentage cover and species richness data from four 50 cm by 50 cm quadrats. Net ecosystem carbon dioxide exchange, photosynthesis and respiration data were measured with an Infra-red Gas Analyser (IRGA); methane, carbon dioxide and nitrous oxide data were measured using gas chromatography; nitrate and ammonium from soil samples extracted with potassium chloride; carbon and nitrogen from soils extracted with water; and carbon and nitrogen stocks measured through combustion analysis. The experiment used seeds and plug plants to create different plant communities on the bare chalk on Winklebury Hill and tested the resulting carbon and nutrient cycling rates and compared these to the characteristics of different plant functional groups. The experiment ran from 2013 to 2016 and this dataset contains data from 2016 only. This experiment was part of the Wessex BESS project, a six-year (2011-2017) project aimed at understanding how biodiversity underpins the ecosystem functions and services that landscapes provide.

本数据集收录了来自英国温克伯里山实验的植被调查数据、土壤中硝酸盐和铵浓度、硝化作用和矿化速率、微生物生物量和碳氮库存数据。植被调查包括四个50厘米×50厘米样方中总物种覆盖率及物种丰富度数据。净生态系统二氧化碳交换、光合作用和呼吸数据采用红外气体分析仪（IRGA）进行测量；甲烷、二氧化碳和一氧化二氮数据通过气相色谱法测定；硝酸盐和铵从用氯化钾提取的土壤样品中获取；碳氮则从用水提取的土壤中测定；碳氮库存通过燃烧分析法测量。实验采用种子和插苗在温克伯里山的裸露白垩土上创建不同的植物群落，并测试了由此产生的碳和养分循环速率，并将其与不同植物功能组的特征进行比较。该实验于2013年至2016年进行，本数据集仅包含2016年的数据。该实验是韦塞克斯生物地球系统科学项目（Wessex BESS项目）的一部分，该项目为期六年（2011-2017年），旨在理解生物多样性如何支撑景观提供的生态系统功能和服务的理解。关于本数据集的详细信息，请参阅https://doi.org/10.5285/e8a1bf2d-bc6b-452f-ab9d-40fa2288fce6。
