“…There are significant differences between the plots with various ecological restoration modes and CK on the slope ( P< 0.01), implying that each mode has a certain ability to prevent runoff and erosion production. The slope mode can not only intercept runoff and erosion caused by rainfall, but also increase the rainfall infiltration rate, increase the soil water conservation effect, benefit vegetation growth and even enhance slope stability (Ma et al, 2022). However, there are significant differences in the prevention and control effects of the different modes on runoff and erosion ( P <0.01).…”

In the coal base of Ningdong, there are many ecological problems associated with the existing local technologies, such as the imperfect technical system, a poor engineering effect, limited generalization value, and the lack of monitoring and evaluation. Based on the screening and integration of the existing technologies in the coal base of Ningdong, we have designed and constructed 14 ecological restoration plots in this study. The 14 plots were composed of two replicates for each of six technical modes and CK treatment (nothing treatment). These technical modes include ecological bag, ecological rod, wire gabion, gravel sand barrier, living sand barrier and wheat straw sand barrier modes. The 14 plots were all constructed in the slope of Yangchangwan waste dump of Ningdong. Several monitoring indicators were selected for vegetation growth observation and data collection, including erosion amount, runoff amount, runoff depth, richness, coverage, herbal biomass, bush biomass and total biomass. Furthermore, the TOPSIS (Technique for Order Preference by Similarity to Ideal Solution) method was utilized to evaluate the effects of the six ecological restoration modes. The results showed that the wheat straw sand barrier mode area had the best vegetation restoration effect, with coverage of 45%, richness of 1.23 and an aboveground biomass of 0.60 kg m -2 . Its monitoring results were 45.16%, 43.02%, and 71.43% higher than in the CK, respectively. The gravel sand barrier model presented the least runoff and erosion yield, and its total erosion was 133.46 g m -2 which was only 26.80% of the CK. The runoff amount was 863.32 cm 3 m -2 , even 50.00% less than CK. The TOPSIS results show that the living sand barrier, gravel sand barrier, and wire gabion modes are the three best ecological restoration modes overall.

“…The ecological projects implemented in the subregion are shown in Table 6. For the purpose of curbing desertification and protecting cropland, ecological projects in Region I are related to the forest, cropland, and grassland [2]. The main human activities in Region II pertain to cropland and grassland, which is closely related to the Restoring Cropland to Grassland Program and Cropland Protection Program implemented in the region [71].…”

“…Vegetation is the manifestation of the ecological environment and a crucial factor in the development of a ground landscape system [1,2]. It not only takes part in the land-atmosphere energy cycle and coupled carbon-water cycle but also is an important component in ecological projects to curb desertification and conserve water and soil [3,4].…”

To tackle ecological problems, many ecological restoration projects have been implemented in northern China. Identifying the drivers of vegetation change is critical for continued ecological engineering. In this study, three typical ecological reserves in the Three-North Shelter Forest Program Region (TNSFR) were selected to identify their vegetation development characteristics and driving mechanisms using the normalized difference vegetation index (NDVI), climate factors, and land use data. The results show that (1) NDVIs increased in the range of human activities of all of the three ecological reserves, indicating an obvious effect of the vegetation restoration projects. (2) In the planting period, vegetation restoration was mainly correlated with human activities. After entering the tending period, the impact of climate changes on vegetation dynamics was enhanced. (3) Temperature and precipitation provided approximate driving effects on vegetation dynamics in Region I, while vegetation dynamics in Regions II and III were more strongly correlated with precipitation. (4) The proportion of areas with ecological measures exceeded 50% in all three regions. In short, ecological projects in the three ecological reserves dominated the quantity of vegetation restoration, while climate changes influenced the quality of vegetation restoration.

“…Alarming data show that desertification covers 40% of the global land surface [2]. The Chinese Government has provided the world with a series of experiences in desertification control, such as the Three-North Shelterbelt Program and the Beijing-Tianjin Sandstorm-Control Program [3,4]. Africa built the "Great Green Wall" in the Sahel region to achieve healthier living goals and promote human health and well-being [5].…”

Vegetation plays a leading role in restoring desert ecosystems and increasing productivity. In this study, we elucidate the improvement effects of different restoration areas of Populus alba on the soil particle distribution, sedimentation environment, and fractal characteristics. We selected the restoration areas of P. alba × Caragana korshinskii (YN), P. alba × Hedysarum leave (YY), and P. alba × Hedysarum scoparium (YH), which have a history of twenty-one years. We analyzed the soil nutrients, soil particle size, soil particle size parameters, soil fractal dimension (D) values, and soil multifractal parameters at soil depths of 0–80 cm. We found that the YN, YY, and YH significantly increased the soil nutrients and soil fine particles (p < 0.05) and changed the deposition pattern of the soil particles in the sandy area. The YN, YY, and YH promote soil particle refinement and reduce the sorting performance of the soil particles. The vegetation promotes extremely positive-skewed and very leptokurtic soil particle distributions. The D values in the YN, YY, and YH restoration areas increased by 7.62%–27.94%, 7.36%–26.28%, and 7.10%–17.92%, respectively, relative to those of the LS. The construction of the different restoration areas of P. alba has made the distribution of the soil particles nonuniform. Compared with the YY and YH plantations, the distribution range of the soil particles in the YN plantation is wider, and the distribution heterogeneity is greater. In addition, we found that the fractal parameters are influenced by the soil physicochemical properties, the depositional environment, and vegetation factors. Therefore, we believe that D values and multifractal parameters are necessary as additional information for desert soil texture improvement. The results of this study provide a scientific and theoretical basis for the future revegetation of deserts.
