Soil physico-chemical properties 1978 [Countryside Survey]

This dataset consists of soil physico-chemical properties (pH and loss on ignition) from soils sampled across Great Britain in 1978. The Countryside Survey is a unique study or 'audit' of the natural resources of the UK's countryside. The sample sites are chosen from a stratified random sample, based on a 15 by 15 km grid of GB. Surveys have been carried out in 1978, 1984, 1990, 1998 and 2007 by the Centre for Ecology & Hydrology, with repeated visits to the majority of squares. The countryside is sampled and surveyed using rigorous scientific methods, allowing us to compare new results with those from previous surveys. In this way we can detect the gradual and subtle changes that occur in the UK's countryside over time. In addition to soil data, habitat areas, vegetation species data, linear habitat data, and freshwater habitat data are also gathered by Countryside Survey.

本数据集包含了1978年在英国全境采集的土壤物理化学性质（如pH值和灼烧损失）数据。乡村调查是对英国乡村自然资源的独特研究或‘审计’。样本点基于GB 15×15公里网格进行分层随机抽样选取。该调查由生态与水文中心在1978年、1984年、1990年、1998年和2007年进行，并对大多数方格进行了重复访问。乡村的调查和采样均采用严谨的科学研究方法，使我们能够将新结果与先前调查的结果进行比较。通过这种方式，我们可以检测到英国乡村随时间逐渐发生的微妙变化。除了土壤数据外，乡村调查还收集了栖息地面积、植被物种数据、线性栖息地数据和淡水栖息地数据。有关本数据集的详细信息可在https://doi.org/10.5285/85c71959-0f7c-4f04-b3a7-152673107a85找到。
