The succession characteristics of soil erosion during different vegetation succession stages in dry-hot river valley of Jinsha River, upper reaches of Yangtze River

Effects of gravel on soil and vegetation properties of alpine grassland on the Qinghai-Tibetan plateau

“…Moreover, alpine grassland soil is very thin and contains less organic matter content. Once the topsoil is destroyed, the stored nutrients in the soil pools are lost through multiple pathways, such as water and wind erosion (Lin et al, 2014), which makes restoration difficult. The low nutrient supply was another reason for the decrease in the FVC and AGB in the alpine grassland.…”

Combined effects of climate, restoration measures and slope position in change in soil chemical properties and nutrient loss across lands affected by the Wenchuan Earthquake in China

“…On the other hand, despite restoration measures used or not, when bare land with steep slopes and fine soil texture caused by rock falls and landslides has little capacity to moderate surface water infiltration, rainfall directly removes soil nutrients, leading to overall decreased soil nutrient content, especially in subtropical monsoon climate zones, which experience a higher decrease in SOC, TN, TP, TK, and AHN due to frequent rainfall events. This means a concomitant decrease in soil quality with reverse ecological succession or continuous disturbance (Arbelo Rodríguez et al, 2002;Lin et al, 2014).…”

“…In this study, we regarded 'destroyed and treated' and 'destroyed and untreated' sites as beginning at the start of restoration in 2011. We chose the method of "space-fortime", which creates a time sequence by spatial sequence (Walker et al, 2010;Lin et al, 2014), to select 'undestroyed' sites as representing the original phase to compare with 'treated' and 'destroyed and untreated' sites. After the construction of earthworks and foundation engineering in March 2011, we set up two 5 m-wide, and 100 m-long transect belts at 20 m intervals in August 2011, which were about 5 m away from and orthogonal to the bottom of each research site's slope.…”

Diversity and conservation of plant species in dry valleys, southwest China

“…However, such unique ecosystems tend to make the dry valleys more vulnerable to be damaged which results in its biological diversity loss and dynamics and resilience decreasing. On the one hand, gully erosion is one of the most important environmental problems in dry valleys due to the high sediment yield from the gully (Dong et al 2014;Lin et al 2014). On the other hand, human population growth and natural resources exploitation have led to serious ecosystem degradation, and native vegetation reduction.…”
