“…Different organs of plants have their specific functions, growth and turnover rates, resulting in differences in nutrient content among organs [ 8 ]. The complex feedback relationship between organisms and climate and terrain can regulate the characteristics of C:N:P:K [ 17 ]. Site type is a complex of site factors such as geology, climate, hydrology and soil microenvironment.…”

The essence of plant ecological stoichiometry is to study the relationships between species and their environment, including nutrient absorption, utilization and cycling processes as well as the nutrient limitation of plants. Plants can regulate nutrient elements and adapt to environmental changes. To understand the adaptation mechanism, it is important to take plants as a whole and quantify the correlation between the chemometrics of different organs. Ammopiptanthus mongolicus is within the second-class group of rare–endangered plants in China and is the only evergreen broad-leaved shrub in desert areas. We analyzed the ecological stoichiometric characteristics of leaves, stems, roots, flowers and seeds of A. mongolicus in five habitats, namely fixed sandy land, semi-fixed sandy land, stony–sandy land, alluvial gravel slope and saline–alkali land. We found that (1) the nutrient contents of N, P and K were in the order of seed > flower > leaf > root > stem. The enrichment of the N, P and K in the reproductive organs promoted the transition from vegetative growth to reproductive growth. Additionally, (2) the contents of C, N, P and K and their stoichiometric ratios in different organs varied among different habitat types. The storage capacity of C, N and P was higher in sandy soil (fixed and semi-fixed sandy land), whereas the content of K was higher in gravelly soil (stony–sandy land and alluvial gravel slope), and the C:N, C:P and N:P were significantly higher in gravelly soil than those in sandy soil. A. mongolicus had higher nutrient use efficiency in stony–sandy land and alluvial gravel slope. Furthermore, (3) the C:N and N:P ratios in each organ were relatively stable among different habitats, whereas the K:P ratio varied greatly. The N:P ratios of leaves were all greater than 16 in different habitats, indicating that the growth was mainly limited by P. Moreover, (4) except for the P element, the content of each element and its stoichiometric ratio were affected by the interaction between organs and habitat. Habitat had a greater impact on C content, whereas organs had a greater influence on N, P and K content and C:N, C:P, C:K and N:P.

“…Natural forest communities perform better than plantations in protecting biodiversity and enhancing ecosystem services oriented towards environmental sustainability [13] . Therefore, leveraging species from natural forest communities to form mixed communities in restoration projects can provide a theoretical basis for tackling the challenges of inefficient forest recovery [18] .…”

Pinus yunnanensis (Pinaceae) is an endemic tree species that only can be found in southwest China, it is also a native suitable for afforestation in this region. However, the natural forest of P. yunnanensis has been widely degraded due to long-term external disturbances, resulting in the formation of monoculture forests. Based on species across different strata in natural forest data from three P. yunnanensis vegetation types, evergreen mixed coniferous broad-leaved forests (MECF), mixed deciduous coniferous broad-leaved forests (MDCF), and evergreen coniferous forests (ECF), we evaluated the taxonomic and phylogenetic alpha (α) and beta (β) diversity among three P. yunnanensis vegetation types and determined the optimal ecological P. yunnanensis community configuration. The results showed that a total of 121 plant species belonging to 33 families and 55 genera were recorded, including 49 and 72 species in the tree and shrub layers, respectively. The taxonomic and phylogenetic α diversity was highest in the MDCF in both tree and shrub layers, indicating these forests’ richness in species variety and evolutionary history. The taxonomic β diversity was highest in MECF and ECF in the tree and shrub layers, respectively, while phylogenetic β diversity was highest in ECF and MDCF. Based on an upset plot analysis, we found that the P. yunnanensis-Alnus nepalensis community within the MDCF exhibited the highest α and β diversity. For Pinus afforestation, we recommend a species mix that including P. yunnanensis (a dominant species), Alnus nepalensis (a dominant and nitrogen-fixing species), Quercus griffithii (a deciduous broad-leaved species) and Rhododendron (a regional endemic). Our findings support the notion that mixed forests possess greater diversity and highlight the importance of considering multi-species combinations in ecological restoration, including mixed species with different leaf life habits (evergreen versus deciduous) species and the endemic species of this region. Our findings also have a direct implication for forest management and afforestation and reforestation practices. Subjects: Biodiversity, Ecology, Plant Ecology

“…It acts as a green protective umbrella for the soil, playing a vital role in preventing soil erosion, regulating the hydrological cycle, and conserving water resources. Vegetation also lays a foundation for development projects that yield economic, ecological, and social benefits [6]. The proliferation of plantation vegetation enhances soil anti-scouring, permeability, and water storage capacity [7].…”

The establishment of protective forests plays a crucial role in mitigating soil erosion on slopes within hilly and gully regions. However, in practical applications, the configuration of protective forests on slopes is intricate and diverse, and the suitability and rationality of different configuration patterns for various slope sections have not been thoroughly investigated. This study focuses on a 40-year-old artificial protective forest, examining 16 different configuration patterns on the top, middle, and lower slopes. It compares the growth conditions, community structure stability, and characteristics of the saturated soil’s hydraulic conductivity. The findings indicate that the top slope should be identified as a critical area for slope protection. The optimal configuration for this area is the “tree + grass” pattern with a spacing of 5 m × 5 m, which promotes the optimal growth of tree species and effectively reduces the surface runoff of gravel particles ranging from 1 cm to 3 cm in diameter. On the middle slope, the “tree + shrub + grass” structure proves effective in slowing down the erosive force of slope runoff. The recommended spacing for trees is 5 m × 6 m, and for understory shrubs, it is 1 m × 6 m. This configuration pattern results in the most stable structure for the plant community and maximizes the water conservation potential of forest litter. By analyzing the characteristics of the saturated soil’s hydraulic conductivity, we find that the complexity of the plant configuration on the lower slopes is correlated with a greater coefficient of variation in the saturated soil’s hydraulic conductivity. Nevertheless, there is no significant difference in the average soil saturated hydraulic conductivity per unit area between the different configuration patterns. Consequently, the lower slope can rely on the natural recovery of herbaceous plants. The results of this research contribute valuable scientific and technical insights to the management of soil erosion in hilly and gully areas, both in China and around the world.
