A dataset of soil monitoring of the Liaohe Estuary Wetland during 2016–2021

Abstract

The Liaohe Estuary wetland falls into category of northern coastal estuary wetlands. Dominated by species such as Phragmites australis (Cav.) Trin. ex and Steud Suaeda salsa (L.) Pall., the primary soil type in this wetland is coastal salt marsh soil. This dataset includes the long-term positioning observations from Liaoning Panjin Wetland Ecosystem National Field Scientific Observation and Research Station during 2016—2021. The primary data observation indicators include soil bulk density, saturated water conductivity, soil water content, pH, REDOX potential, calcium ions, potassium ions, magnesium ions, sodium ions, carbonate ions, bicarbonate ions, chloride ions, sulfate ions, total nitrogen, nitrite nitrogen, total phosphorus, available phosphorus, total potassium, organic matter, organic carbon, heavy metal ions, and other physical and chemical properties. In the observation data, apart from the oxidation-reduction potential observed in situ at the observation sites using a portable instrument, all other indicators are collected as soil samples at fixed observations sites. The samples are then taken back to the laboratory and analyzed using standardized instruments to determine various indicators. The establishment of observation datasets furnishes basic data for enhancing the regional wetland soil environmental quality monitoring system and establishing the soil quality environmental monitoring network. It is expected to contribute to exploring the patterns of change, ecological process, evolution trend, and driving mechanism of regional wetland soil ecosystems. Moreover, it can provide long-term data support for solving basic and key problems in the research of northern coastal wetlands as well as regional environment and social public services.
