“…The effect of OMC on permeability was less pronounced, Spearman's correlation coefficient was negative and amounted to -0.54 (Table 2). The performed statistical analysis showed that the mineralization of organic matter in the studied soils resulted in an increase in permeability, which is in agreement with the findings of Zeitz and Velty (2002) but in contrast with the work of Zongping et al (2016).…”

Open-pit lignite mining requires drainage of the deposit. The depression cone, formed as a result of these activities, has a varied surface and depth, and these features are shaped primarily by the geological structure and by the thickness of the caprock layer. In some of the areas covered by the depression cone, soil productivity may deteriorate, and a related yield reduction may occur, providing the basis for the payment of applied compensations for the owners of such areas. The aim of the study was to assess the condition of selected soils in the vicinity of the planned excavation (Field B) of the Drzewce lignite open pit mine (central Poland). Six profi les were excavated in organic and mineral-organic soils. The locations of the test points were chosen to represent soils that meet the criteria of habitats prone to drainage degradation. The morphological structure of the studied soils and their analysed properties indicate that they have already been drained (probably due to the infl uence of climate and cultivation), but does not exclude the possible acceleration and enhancement of this process by the commencement of mining activities. For most of the analysed features, a high correlation between their value and organic matter content was observed. Given that the possible commencement of opencast mining operations may signifi cantly accelerate and enhance the already initiated mursh-forming process, it is reasonable to conduct systematic research at the measuring points proposed in the study.

“…The rapid expansion of forest land reflects the success of ecological restoration programmes, and the expansion of orchards and construction land reflect rapid economic development. Severe soil and water losses in this area have placed enormous pressure on social and economic development 51 . The rapid development of the economy has led to rapid urbanization 52 ; hence, although the construction land area occupies a very small proportion of the study area, an obvious growth trend was evident.…”

Changes in land cover have become key components of global environmental change and represent the impact of human activity. To better understand the fundamental processes of land transition characteristics before and after the implementation of ecological programmes, we determined the dominant systematic changes in land cover in Yongshou, a hilly-gully region on the Loess Plateau. This was achieved by performing an in-depth analysis of a cross-tabulation matrix and a modified spatial dynamic degree model. Our results indicated that (1) forest land and cultivated land were the most important land cover types in Yongshou and their persistence would greatly affect the landscape pattern of the entire region; (2) the most significant changing signals in the study area during the periods 1992–2000 and 2000–2013 were from immature forest land to forest land, cultivated land to orchards and orchards to construction land; and (3) the region that experienced the most changes during 1992–2000 was the densely populated county seat of Yongshou; however, from 2000–2013, the region of most changes was Changning, a town located in the northcentral region of Yongshou. These findings reveal the main characteristics of the land cover changes in this region and provide insight into the processes underlying these changes.

“…In the different parts (summit, backslope and footslope) of each plot, the morphological features of vegetation were investigated based on standard individual measurements in the field (Puigdefabregas, ). Specifically, biomass (BM, g m ‐2 ) and plant coverage (PC, %) were measured by weighing standard samples (selected by the average standard tree method) and photo analysis in the field, respectively (Ren et al ., ). Botanical water storage capacity per unit of biomass (WSC, g g ‐1 ) was measured by soaking samples (selected by average standard tree method) in distilled water for 12 h and weighing (Brandt, ; Yu et al ., ).…”

Soil erosion hinders the recovery and development of ecosystems in semiarid regions. Rainstorms, coupled with the absence of vegetation and improper land management, are important causes of soil erosion in such areas. Greater effort should be made to quantify the initial erosion processes and try to find better solutions for soil and water conservation. In this research, 54 rainfall simulations were performed to assess the impacts of vegetation patterns on soil erosion in a semiarid area of the Loess Plateau, China. Three rainfall intensities (15 mm h‐1, 30 mm h‐1 and 60 mm h‐1) and six vegetation patterns (arbors‐shrubs‐grass ‐A‐S‐G‐, arbors‐grass‐shrubs ‐A‐G‐S‐, shrubs‐arbors‐grass ‐S‐A‐G‐, shrubs‐grass‐arbors ‐S‐G‐A‐, grass‐shrubs‐arbors ‐G‐S‐A‐ and grass‐arbors‐shrubs ‐G‐A‐S‐) were examined at different slope positions (summits, backslopes and footslopes) in the plots (33.3%, 33.3%, 33.3%), respectively. Results showed that the response of soil erosion to rainfall intensity differed under different vegetation patterns. On average, increasing rainfall intensity by 2 to 4 times induced increases of 3.1 to 12.5 times in total runoff and 6.9 to 46.4 times in total sediment yield, respectively. Moreover, if total biomass was held constant across the slope, the patterns of A‐G‐S and A‐S‐G (planting arbor at the summit position) had the highest runoff (18.34 L m‐2 h‐1) and soil losses (197.98 g m‐2 h‐1), while S‐A‐G had the lowest runoff (5.51 L m‐2 h‐1) and soil loss (21.77 g m‐2 h‐1). As indicated by redundancy analysis (RDA) and Pearson correlation results, a greater volume of vegetation located on the back‐ and footslopes acted as effective buffers to prevent runoff generation and sediment yield. Our findings indicated that adjusting vegetation position along slopes can be a crucial tool to control water erosion and benefit ecosystem restoration on the Loess Plateau and other similar regions of the world.
