Soil salinization is one of the most common land desertification processes that can be found worldwide. It is a certainly severe environment hazard and threatens the stability of ecosystems. As a rapid and inexpensive tool, remote sensing technology combining with the measurements of soil spectra has been widely concerned on identifying and mapping salt effect on lands. However, as effects of the soil moisture often immerge the effects of salt to soil reflectance spectra, soil moisture became a major factor to restrict soil salinity monitoring from soil reflectance. High soil moisture content will lead to failure on soil salinity estimation from soil reflectance data. In this paper, a semianalytical model using an exponent function was developed to estimate soil salt content (SSC) under different moisture levels based on a control laboratory experiment. And the root-mean-square error and mean relative error were 0.799 g/kg and 31.294%, respectively, when the model was applied to estimate SSCs by wet soil reflectance. To sum up, considering both effects of soil moisture and soil salt on soil reflectance, the semianalytical model reduced SSC estimated error. The approach presented in this paper provides a new way of estimating soil salinity from soil spectra under various soil moisture conditions, and it will be a potential application for large-scale SSC mapping.

Estimating Soil Salinity Under Various Moisture Conditions: An Experimental Study

Quantified information on land degradation and restoration is needed to support policies for sustainable ecosystem management and socioeconomic development. The arid and semiarid zones of China (ASZC) have experienced significant land degradation, and in response to such degradation, multiple ecological projects were implemented. In this study, remote sensing was used to identify degrading areas and where the degraded areas have been restored from 1990 in this ecologically sensitive region. Specifically, we integrated datasets from the ChinaCover and Moderate Resolution Imaging Spectroradiometer products to characterize changes in vegetation, ecosystems, and environmental conditions. The results confirmed that deforestation, desertification, grassland degradation, wetland loss, and the encroachment upon farmlands were notable in the ASZC. Agricultural activity has cultivated extensive areas of natural ecosystems (46,474 km²). The expansion of built‐up lands in terms of national policies has destroyed large areas of natural (5,487 km²) and agricultural (4,138 km²) ecosystems and continually results in negative impacts on ecological conservation. China has restored some lands (7,732 km² from farmlands and 24,904 km² from barren lands) and improved ecosystems, as characterized by increases in the normalized different vegetation index, leaf area index, net primary productivity, and gross primary productivity values in the ASZC, especially after the implementation of many ecological projects. However, it is also necessary to document the conclusions and lessons from these projects to guide future ecological policies and projects in the context of the substantial new challenges facing the protection of this ecologically sensitive environment.

Trinitrotoluene (TNT), a commonly used explosive for military and industrial applications, can cause serious environmental pollution. 28-day laboratory pot experiment was carried out applying bioaugmentation using laboratory selected bacterial strains as inoculum, biostimulation with molasses and cabbage leaf extract, and phytoremediation using rye and blue fenugreek to study the effect of these treatments on TNT removal and changes in soil microbial community responsible for contaminant degradation. Chemical analyses revealed significant decreases in TNT concentrations, including reduction of some of the TNT to its amino derivates during the 28-day tests. The combination of bioaugmentation-biostimulation approach coupled with rye cultivation had the most profound effect on TNT degradation. Although plants enhanced the total microbial community abundance, blue fenugreek cultivation did not significantly affect the TNT degradation rate. The results from molecular analyses suggested the survival and...
