Plant aboveground and belowground standing biomass measurements in the Conwy catchment in North Wales (2013 and 2014)

The data consists of, standing aboveground biomass, and belowground biomass measurements, from sites in the Conwy catchment. Standing aboveground biomass was measured at 7 sites and belowground biomass measurements were made at 8 sites. Data were collected in 2013 and 2014. The sites were chosen to represent habitat types and the terrestrial productivity gradient in Britain from intensive agriculturally managed lowland grasslands through to montane heath. Standing aboveground biomass (grams of dry mass per metre square) in habitats dominated by herbaceous biomass was measured on 1x1 metre quadrats in four plots per site. Standing aboveground biomass in woodlands was measured in two 200 square metre areas by means of stem cores and litter collections. Belowground total root biomass (grams of dry mass per square metre) was assessed for the topsoil 0-15 centimetres in three plots per site.

Measurements were undertaken by trained members of staff from Bangor University and the Centre for Ecology & Hydrology.

This data was collected for the NERC project 'The Multi-Scale Response of Water quality, Biodiversity and Carbon Sequestration to Coupled Macronutrient Cycling from Source to Sea' (NE/J011991/1). The project is also referred to as Turf2Surf.

本数据集包含康威流域（Conwy catchment）各采样点的地上现存生物量与地下生物量实测数据。其中地上现存生物量测量覆盖7个采样点，地下生物量测量则覆盖8个采样点，数据采集于2013年与2014年。本次选取的采样点旨在代表英国境内的生境类型与陆地生产力梯度，涵盖从集约化农业管理的低地草地到山地荒原的全部区间。
对于以草本生物量为优势类群的生境，采用1米×1米样方在每个采样点的4个样地中开展地上现存生物量测定，计量单位为克干重/平方米；对于林地生境，则通过茎芯取样与枯落物收集的方式，在2个200平方米的区域内完成地上生物量测量。
地下总根生物量（计量单位为克干重/平方米）的测定针对0-15厘米表层土壤，在每个采样点的3个样地中开展。
本次实测由班戈大学（Bangor University）与生态与水文中心（Centre for Ecology & Hydrology）的受训人员完成。
本数据集采集自英国自然环境研究委员会（NERC）资助的项目"水质、生物多样性与碳固持对从源到海耦合大量营养元素循环的多尺度响应"（NE/J011991/1），该项目亦被称为Turf2Surf。
