A scale for evaluating the willingness of national forest farm to participate in forest carbon sink project.

In recent years, the development of Forest Carbon Sink Project (FCSP) has become a key focus within forestry sector. Despite this, decision-makers often lack reliable tools to assess forest owners' willingness to engage in this project. This study aims to develop, validate and evaluate a rational value perception scale as the tool to understand the willingness of forest manager.

Combining metal and sulfate isotopes measurements to identify different anthropogenic impacts on dissolved heavy metals levels in river water.

Dissolved heavy metals (DHMs) contamination has raised global concern for ecological and human health development. Weathering of sulfide-bearing ore metals can produce acidic, sulfate-rich solutions in the presence of water and oxygen (O), and DHMs are released to deprave the river water quality. Sulfur and oxygen isotope signatures (δS and δO) could identify this pyrite-derived sulfate; however, it is yet not well known whether the δS and δO values could limit the DHMs sources and illustrate anthropogenic impacts on DHMs along the river corridor.

Isotope evidence for temporal and spatial variations of anthropogenic sulfate input in the Yihe River during the last decade.

Pyrite oxidation and sedimentary sulfate dissolution are the primary components of riverine sulfate (SO) and are predominant in global SO flux into the ocean. However, the proportions of anthropogenic SO inputs have been unclear, and their tempo-spatial variations due to human activities have been unknown. Thus, field work was conducted in a spatially heterogeneous human-affected area of the Yihe River Basin (YRB) during a wet year (2010) and drought years (2017/2018).
