“…As population increases and urbanization accelerates in most countries, arable land is gradually decreasing. This case is especial for China (Shao, Cui, & Bai, 2012;Shao, Chen, & Marian, 2015;Shao, Lu, Xu, & Brestic, 2017). Modern agriculture is facing a serious challenge beyond the coming decades.…”

Salt stress is a major problem happening in almost all the world, affecting soil metabolism and acting further negatively soil fertility and soil quality, causing land degradation and low ecosystem service functions and ecosystem productivity. In marshy area as one type of important marginal land resources, salt is also the main barrier to be improved and the driving force to make vegetation succeed. This commentary briefly reviews the main advance focusing on salt‐affected soil and introduced the publications in this Special Issue: Salt Soil Improvement and Efficient Development in Land Degradation & Development 29, 2018, to promote global cooperation for studying salt‐affecting soil quality, land degradation, and eco‐restoration.

“…Anthropogenic disturbances could lead to water quality degradation in these ecologically important ecosystems [2,7,16,17]. For example, peat-harvested peatlands possess higher concentrations of major cations compared to unharvested peatlands, which may be attributed to the exposure of minerotrophic fen peat [18].…”

Abstract:Compared with the extensively surveyed temperate and boreal peatlands, subtropical peatlands have received rather little scientific attention. In this study, spatial variations in water chemistry were investigated in 57 samples collected from three subtropical peatlands (central China). Generally, water pH and major cation concentrations of these samples approached the characteristics of poor fens along the bog-rich fen gradient. Four distinct groups were identified by cluster analysis and principal component analysis. High concentrations of trace elements in Group I were probably linked to airborne dust pollutants from a nearby road under construction. Low pH values and low major cation concentrations in Group II may be attributed to the great cation exchange capacity of Sphagnum. In contrast, samples in Group III, mainly collected from sites suffering from Sphagnum harvest, showed high pH levels and major cation concentrations. Relatively low concentrations of trace elements (except boron) in Group IV can be regarded as reference conditions for restoration efforts in these peatlands. Taken together, spatial variations in the water chemistry of the three peatlands were closely linked to natural processes (e.g., cation exchange of Sphagnum) and anthropogenic pressures (e.g., Sphagnum harvest). Overall, the mean health risk values of the six trace elements were low, indicating good water quality in these peatlands. This study provided baseline water chemistry information for the sustainable management of these subtropical peatlands, as well as other similar ecosystems.

“…This input induces eutrophication and causes deterioration in river water quality . Then widespread degradation of aquatic environments occurring in lakes, streams and even the oceans can be attributed to the increase of agricultural practices, such as fertilization, tilling, application of pesticides and herbicides . As such, preventing nitrogen and phosphorus input from run‐off into the river is a fundamental way to prevent eutrophication .…”

On upstream of Hunhe River, the riparian zone and water quality has been impacted by increasing anthropogenic activities. Nitrogen and phosphorus run-off the river, has led to eutrophication. In this study, total nitrogen (TN) and total phosphorus (TP) concentrations were measured from different tissues (roots, stems and leaves) of twelve plants from the upstream riparian zone of the Hunhe River. The TN concentration ranged between 6.45 and 39.94 mg/g, while the TP range was 2.77-9.20 mg/g. A positive correlation of r 2 ¼ 0.5157, p < 0.05 was recorded between N/P ratios and TN. This showed that plants growth was limited by N according to the "law of the minimum". The concentrations of TN and TP in leaves were significantly higher than that in roots and stems. There were significant differences among life forms (tree, shrub, and herb) with respect to TP and N/P ratios. The data provided a theoretical guidance to plant species screening for the riparian zone restoration in purpose of the water quality improvement in the Hunhe River.
