“…Individual-tree growth was negatively related to competition The first hypothesis was supported by the large effect sizes of tree size in both the final tree growth and water conservation function models (Table 4 and Figure 4). It was found that tree size greatly positively affects tree growth as well as water conservation function (Zhang B. B. et al, 2021;Dietz et al, 2006;MacFarlane & Kobe, 2006;Matsushita et al, 2015).…”

“…Trees with a developed canopy and high canopy interception may produce large amounts of litter, giving the litter layer a strong interception capacity, and the organic matter generated by litter decomposition can improve soil porosity and permeability (Zhang B. B. et al, 2021; Srinivasarao et al, 2014). In turn, a greater soil storage capacity will promote tree growth due to better soil moisture conditions, resulting in greater canopy rainfall interception (Celentano et al, 2017; Guo et al, 2019).…”

Multifactor relationships between the forest structure and water conservation function ofPicea crassifoliaKom. plantations in Qinghai Province, China

Forest structure and ecosystem function/service relationships have attracted considerable attention; however, knowledge of how forest structure systematically affects water conservation function is still lacking. Such research is urgently needed in Qinghai Province, China's Water Tower, to guide forest structure optimization for plantations with weak water conservation functions. Since healthy, stable tree growth is crucial for forests to fulfill their water conservation functions, this study examined the impacts of forest structure on tree growth. We investigated 115 plots in Qinghai Province and analyzed tree size, size heterogeneity, species diversity, competition and spatial distribution effects on the individual tree growth and water conservation function of Picea crassifolia Kom. using mixed-effect and structural equation models, respectively. Forest structure was important in modulating tree growth and the water conservation function. Tree size had the greatest impact on growth performance and directly enhanced the water conservation function. High-size heterogeneity increased the tree growth rate and directly and indirectly improved the water conservation function via competition. Both individual growth and water conservation function were negatively related to competition between trees. Species diversity promoted P. crassifolia growth under a given degree of neighbourhood competition and indirectly affected the water conservation function by increasing size heterogeneity and reducing competition. An uneven spatial distribution did not influence tree growth but positively affected the water conservation function. Therefore, we emphasize that for plantations to fulfill their water conservation functions, pure forests with homogeneous structures should be transformed into mixed forests with heterogeneous structures.

“…China has the largest monoculture plantation area (~69 × 10 6 ha) worldwide, accounting for 25% of global plantations [1]. The majority of these Chinese plantations are evenaged [2], and in general, even-aged monocultures lead to declines in biodiversity and ecosystem structure and functions [3][4][5][6]. A way to resolve this negative outcome is by converting the plantations into complex mixed-species stands [7][8][9], such as through selecting suitable species for under-planting among the existing monoculture [10][11][12].…”

We investigated how different degrees of shading affected growth, morphology, and biomass allocation in seedlings from two coniferous and three broadleaved species. The experiment was conducted in a shade house over a 1-year period. Our results showed that under increasing shade, seedlings from most species exhibited lower total biomass, net assimilation rates, relative growth rates, root mass ratios, and root/shoot ratios. In contrast, the slenderness quotients, leaf area ratios, and specific leaf areas increased with increasing shade. For coniferous species, growth traits were relatively more plastic (responsive to shade) than morphology or biomass allocation traits, whereas for broadleaved species, growth and biomass allocation were the mostshade-sensitive traits. When comparing coniferous versus broadleaved species, the former had a higher growth plasticity index and lower allocation plasticity than the latter. Root biomass and stem mass ratio were the most and least plastic traits in response to shading. Our results indicate that shade differentially affects coniferous and broadleaved species in terms of their growth, morphology, and biomass allocation. These findings have important implications for the establishment and maintenance of mixed-species stands.
