A dataset of basic soil properties for long-term monitoring sample plot of Shanghai Yangtze River Delta Research Station during 2016-2021

Shanghai Yangtze River Delta Ecology & Environmental Change and Control Research Station (Shanghai Station) is one of the four research station for urban ecosystems approved in 2021. Since 2016, Shanghai Station has carried out long-term soil monitoring. This dataset profile collects the basic soil properties of 12 long-term monitoring plots in different soil layers (0-10cm, 10-20cm, 20-40cm) on different urban-rural gradients at Shanghai Station from 2016 to 2021, including pH value, bulk density, organic matter, total nitrogen, total phosphorus, total potassium, available phosphorus, available potassium, total zinc, total copper, total lead, total chromium. In addition, the dataset includes plot information, soil sampling and preservation, analysis method information table. The datase can be provide a data basis for the study of soil carbon sinks, soil nutrient changes, and heavy metal pollution in megacities.
