“…The LWHC in Japanese evergreen coniferous forests (Sato et al, 2004) was not consistent with that in Chinese tropical rainforests (Zhu et al, 2021) as measured by indoor immersion. It is notable that the LWHC measured by indoor immersion only reflects ideal water‐holding conditions, which is likely higher than the LWHC under actual field conditions (Luara et al, 2022). Our results are consistent with those of previous studies showing that the LWHC of conifer‐broadleaf mixed forests is higher than that of coniferous forests (Bai et al, 2021; Jin et al, 2014; Su & Liu, 2022; Wang et al, 2007; Zhang et al, 2022).…”

“…The hydrological function of forest ecosystems refers to the redistribution and reuse of precipitation through the forest canopy, litter, and soil layers (Cano‐Arboleda et al, 2022; Du et al, 2019; Liu et al, 2023; Sun et al, 2018). Litter is formed by tree leaves, branches, flowers, fruits and animal dung (Da Silva et al, 2018; Luara et al, 2022) and is the surface cover layer of the hydrological function on the vertical structure of forest ecosystems, which plays a non‐negligible role in the forests hydrological function (Lv et al, 2020). The forest litter layer can intercept 10%–20% of natural precipitation, which reduces the infiltration rate of rainwater, thereby preventing runoff and erosion on the soil surface (Giácomo, 2017; Su & Liu, 2022).…”

Although changes in tree species composition profoundly affect the structure, function, and processes of mixed forest ecosystems, there is limited knowledge on the effects of these changes on the hydrological functions of the litter layer in Pinus massoniana conifer‐broadleaf mixed forests in subtropical mountains. Here, we investigated three typical P. massoniana forest stands in southwest China: P. massoniana‐Liquidambar formosana conifer‐deciduous broadleaf mixed forest (Pm + Lf), P. massoniana‐Castanopsis eyrei conifer‐evergreen broadleaf mixed forest (Pm + Ce), and P. massoniana plantation (Pm), and conducted field investigations (litter composition and mass) and indoor immersion experiments to analyse the litter water‐holding capacity (LWHC) of forest stands in their natural state and with artificial ratios combining mixed (needle‐leaf and broad‐leaf) litters. The total litter mass did not significantly differ among the three forest stands (p > 0.05), but significant differences were observed in the needle‐leaf (0.67–2.92 t hm−2), broad‐leaf (0.32–1.89 t hm−2) and bark (0.11–0.34 t hm−2) masses in the undecomposed layer. The LWHC of different stand types was in the order of Pm + Lf > Pm + Ce > Pm. The maximum water‐holding capacity of different artificial ratios of mixed litters was positively proportional to the broad‐leaf mass and inversely proportional to the needle‐leaf mass, and the P. massoniana‐L. formosana mixed litter had a higher maximum water‐holding capacity than the P. massoniana‐C. eyrei mixed litter. The LWHC of mixed forests is mainly influenced by stand structure (tree composition) and litter characteristics, and is positively correlated with leaf area, thickness, dry matter content, and surface roughness. This study revealed that the LWHC can be significantly affected by different P. massoniana stands in subtropical mountains. This study will aid the sustainable and ecological management of forest in subtropical mountains, and P. massoniana plantations should be gradually converted into mixed conifer‐broadleaf forests with greater LWHC and buffering capacity.

“…The litter production in forest ecosystems depends on several ecological factors, such as the climate, species composition, stand age, and site quality (Dodonov et al 2016;König et al 2002;Pereira et al 2022;Yang et al 2005). In the present study, two sites possessing different passive restoration ages were compared, but with an identical macroclimate as well as soil type.…”

“…Although passive restoration models are simple, inexpensive, and based on natural regeneration (Holl 2002;Schrautzer et al 2007), they are relatively slow processes when compared to active restoration models (Pereira et al 2021;Pereira et al 2022). As a natural process, passive restoration is unpredictable.…”

“…Thus, the high costs hamper the application of artificial restoration techniques, especially in remote and mountainous areas. Although natural recovery (passive restoration) is convenient and inexpensive, it is a relatively slow process which may take decades or even centuries (Cullen et al 1998;Pereira et al 2021Pereira et al , 2022Tonello et al 2022). How to restore the ecosystems of RCSs economically and effectively in alpine regions needs to be further studied.…”

Background The rock cut slope (RCS) could cause damage to regional ecological functions and landscapes and requires recovery. Biological soil crusts (BSCs) are pioneer and dominant colonizers during the initial recovery stage. To accelerate the natural recovery of RCS, the development process and influencing agents of BSC should be revealed. Thus, the area index of crevices (IR), BSC coverage (COV) and biomass (BM), soil weight (SW), and major soil nutrients [organic carbon (OC), total nitrogen (TN) and total phosphorus (TP)] content, collected from 164 quadrats on 13 RCSs in the mountainous area of west Sichuan Province, China, were measured, to explore the effect of crevice of RCS on BSC development. Results Soil OC, TN and TP on RCSs ranged from 18.61 to 123.03 g kg−1, 0.96 to 6.02 g kg−1 and 0.52 to 2.46 g kg−1, respectively, and were approximately to or higher than those on natural slopes. The OC, TN and TP contents in soils elevated unsystematically with recovery time of RCSs. BSCs on RCS distributed along crevices generally and firstly. During the first 13 years of natural recovery, COV, BM and SW ranged from 6.5 to 28.2%, 14.43 to 67.25 g m−2, and 127.69 to 1277.74 g m−2, respectively. COV, BM and SW increased linearly with IR on RCSs. The positive correlation between COV and BM and IR was insignificantly impacted by bedrock, slope aspect and altitude within the recovery time less than 13 years. COV and BM on RCSs increased significantly when the recovery time is more than 27 years. Conclusions Crevice on RCSs could be a major environmental factor which is conducive to BSC development and soil accumulation through creating a space for water and soil particle. Furthermore, with the increase of recovery time of RCSs, BSCs may grow and reach a stable state with the promotion of soil nutrients, plant growth and microbial activity. These results provide a development process of BSC that from inside to outside the crevices on RCSs. In the areas with stable rock strata and a low risk of geological disasters, purposeful improvement in crevice density on RCS may effectively accelerate BSC development.
