“…The reciprocal action of erosive forces, such as wind erosion and surface subsidence, frequently acts on plants growing in areas of coal mining collapse. These loads are transmitted to the plant roots, causing fatigue in the root system 34 . As the root system was repeatedly subjected to tensile force in the fatigue state, the internal microstructure of the root system was bound to change.…”

This study aimed to reveal the soil reinforcement by shrub root systems after repeated stress from external forces, such as high winds and runoff, for extended periods in the wind-hydraulic compound erosion zone. Using the widely distributed Shandong mine area soil and water-conserving plant species, Caragana microphylla, Hippophae rhamnoides, and Artemisia ordosica, cyclic loading tests were conducted on taproots of the three plant species (1–5 mm diameter) via a TY8000 servo-type machine to investigate the taproots’ tensile properties response to repeated loading–unloading using simulated high wind pulling and runoff scouring. Our study revealed that the tensile force was positively correlated with the root diameter but the tensile strength was negatively correlated under monotonic and cyclic loading of the three plants’ taproots. However, after cyclic loading, the three plant species' taproots significantly enhanced the tensile force and strength more than monotonic loading (P < 0.05). The taproot force–displacement hysteresis curves of the three plant species revealed obvious cyclic characteristics. Structural equation modeling analysis revealed that root diameter and damage method directly affected the taproots' survival rate, reflecting their sustainable soil reinforcement capacity. The damage method significantly influenced the soil reinforcement more than the root diameter. Our findings reveal that the plant species' taproots can adapt more to the external environment and enhance their resistance to erosion after natural low perimeter erosion damage, effectively inducing soil reinforcement. Particularly, the taproots of Caragana microphylla have superior soil-fixing ability and can be used for ecological restoration.

“…In contrast to these long-term effects, short-term effects mainly represent the change in vegetation caused by ground deformation as it occurs, such as damage to plant organs or the loss of entire communities. In the short term over a period of days and weeks, ground deformation squeezes, stretches, slides, and cracks the soil, leading to damage or even death of the vegetation [8]. In the long term extending over months and years, ground deformation alters hydrological processes, such as infiltration, soil evaporation, and runoff, as well as causing the drop or rise of the ground water table [9,10].…”

Ground deformation is one of the most common geological disasters arising in underground mining areas, and mining-induced environmental impacts have resulted in numerous concerns, especially the impacts on the surface vegetation. The evaluation of mining-induced impacts on vegetation is beneficial to revegetation in mining areas; however, the impacts of ground deformation have seldom been systematically evaluated and explained on long time scales despite the long-term existence of ground deformation in underground mining areas. To address this, in this study a vegetation-soil-climate (VSC) model was developed to evaluate the long-term impacts of ground deformation on vegetation, and to reveal its mechanism. The results revealed that the long-term impacts of ground deformation on vegetation result from the degradation of the vegetation and soil when ground deformation occurs, which thereby limits the growth and succession of plants after the ground deformation has occurred. The intensity of the long-term impacts is determined by the severity of the ground deformation, but the duration, climate factors, the substrate conditions of the vegetation and soil before the deformation, and the natural change coefficient of the vegetation and soil are also relevant. Furthermore, the characteristics of the long-term impacts on vegetation were analyzed, and a framework for implementing revegetation and suggestions for the supervision of revegetation in underground mining areas are presented based on the characteristics. The results of this study provide insights into the impacts of mining-induced ground deformation on vegetation on long time scales, considering the comprehensive interactions between the vegetation and other environmental factors, and provide theoretical support for revegetation in underground mining areas.

“…Ground deformation is a common mining-induced disturbance in underground mines, and it has various effects on the surface plant communities (Worlanyo & Jiangfeng, 2021). In the short term, ground deformation squeezes, stretches, slides, and cracks plants, leading to damage or even death of these plants (Bi et al, 2019;Wang et al, 2022). In the long term, ground deformation alters the hydrological processes that are important to plants (Mason et al, 2021), such as the in ltration of precipitation, soil evapotranspiration, and runoff collection, as well as lowering of the water table (Chen et al, 2022;Lechner et al, 2016;Wang et al, 2017), all of which are likely to continuously interfere with the plant succession.…”

Contexts Mining-induced ground deformation has various effects on different plant communities. However, little is known about the effects of ground deformation on plant patterns after spontaneous succession, and there is currently no quantitative approach to the detection of these long-term effects. Objectives A plant community succession model (PCSM) based on cellular automate was developed, and the 30-year plant succession within a subsidence area in the Yungang mining area in China under mining and non-mining scenarios, as well as under two sets of initial conditions (plant-covered and bare), were simulated and compared. Methods The normalized mean square error (NMSE) was applied to test the accuracy of the PCSM and to reveal the effects of ground deformation at the patch scale, which was 0.06–0.59 for simulated and observed plant patterns. Six landscape indicators (contagion index (CONTAG), patch cohesion index (COHESION), landscape division (DIVISION), Shannon’s diversity index (SHDI), Shannon’s evenness index (SHEI), and aggregation index (AI)) were calculated for the mining and non-mining scenarios and compared to reveal the effects at the landscape scale. Results The results show that the DIVISION, SHDI, and SHEI were significantly higher in the mining scenario than in the non-mining scenario under plant-covered conditions; while the DIVISION was greater for the mining scenario than for the non-mining scenario, indicating that the ground deformation resulted in a loose, separated, and mixed plant pattern. The dynamics of the plant coverages and patterns in the two scenarios reflect the negative and positive effects of ground deformation on the tree and shrub communities, respectively. In terms of the shrub and tree communities, the NMSEs fluctuated at a high level under bare conditions, especially at the patch scale of 10 × 10 m, for which it was maintained at >0.5. Conclusion Overall, the mining-induced ground deformation chronically influenced the plant succession by limiting tree communities and promoting shrub communities, and it led to a heterogenous plant pattern. The results of this research provide a reference for detecting the long-term effects of mining-induced ground deformation on plant patterns, and they also provide insights into the effects of underground mining on different plant communities.
