Topsoil invertebrate density estimates from the Countryside Survey of Great Britain, 2007 using a generalized additive model

This dataset presents modelled estimates of soil invertebrate density (individuals m-2) at 1km2 resolution across Great Britain. A Generalized Additive Model approach was used with Countryside Survey soil invertebrate density data from 2007 and including climate, habitat, soil and spatial predictors. The model is based on soil invertebrate density data from 830 locations across Great Britain and is representative of 0-8 cm soil depth. Soil invertebrates were extracted from cores using a dry Tullgren extraction method and enumerated by microscope. The Countryside Survey looks at a range of physical, chemical and biological properties of the topsoil from a representative sample of habitats across the UK. This work was supported by the Natural Environment Research Council award number NE/R016429/1 as part of the UK-SCAPE programme delivering National Capability.

本数据集提供了大不列颠地区土壤无脊椎动物密度（个体/m²）的模拟估计，以1km²的分辨率呈现。该数据集采用广义加性模型方法，结合了来自2007年乡村调查的土壤无脊椎动物密度数据，并纳入了气候、生境、土壤和空间预测因子。模型基于大不列颠830个地点的土壤无脊椎动物密度数据，并代表了0-8cm土壤深度的数据。土壤无脊椎动物通过干式Tullgren提取法从土芯中提取，并使用显微镜进行计数。乡村调查审视了来自英国代表性生境样本的表层土壤的多种物理、化学和生物特性。本研究得到了自然环境研究委员会（Natural Environment Research Council）资助，项目编号NE/R016429/1，作为英国-SCAPE项目的一部分，旨在提升国家能力。关于本数据集的详细信息可在以下链接找到：https://doi.org/10.5285/93207428-aace-4bb5-9073-2eb44ad632d1
