Abstract :
互花米草(Spartina alterniflora)是全球最危险的外来入侵物种之一,对我国滨海湿地的经济、环境及生物多样性造成极大危害.为有效防控互花米草,设置刈割加不同程度遮阴处理的室外样地和刈割加不同水淹深度的室内试验,测定不同处理下不同时期的互花米草叶、茎、根等指标来揭示互花米草在两种处理下生长指标的变化特征.结果表明:(1)在刈割加水淹处理试验中,刈割加20 cm和刈割加25 cm水淹处理对互花米草的茎粗、叶、茎、根生物量有显著抑制作用(P <0.05),刈割加15 cm水淹与对照组互花米草所有生长指标均无显著差异(P> 0.05).(2)在刈割加遮阴处理试验中,所有试验组对互花米草株高、茎粗、单株生物量均有极显著的抑制作用(P <0.01),其中刈割加90%遮阴处理较同期对照组对互花米草抑制程度最高,试验6个月后互花米草株高降低43%、茎粗减少38%、样方内生物量降低86%.(3)刈割加遮阴处理下互花米草绝对生长率均呈现负值,且有机物积累量随遮阴程度增加随之减少,其中刈割加90%遮阴处理下互花米草有机物积累量最少.本研究表明,刈割加高强度遮阴处理可以有效抑制互花米草的生长,治理效果最佳.(图4表5参35)

Abstract :
Over the past decades, the expansion of natural secondary forests has played a crucial role in offsetting the loss of primary forests and combating climate change. Despite this, there is a gap in our understanding of how tree species' growth and mortality patterns vary with elevation in these secondary forests. In this study, we analyzed data from two censuses (spanning a five-year interval) conducted in both evergreen broadleaved forests (EBF) and temperate coniferous forests (TCF), which have been recovering for half a century, across elevation gradients in a subtropical mountain region, Mount Wuyi, China. The results indicated that the relative growth rate (RGR) of EBF (0.028 +/- 0.001 cmcm-1a-1) and the mortality rate (MR) (20.03% +/- 1.70%) were 27.3% and 16.4% higher, respectively, than those of TCF. Interestingly, the trade-off between RGR and MR in EBF weakened as elevation increased, a trend not observed in TCF. Conversely, TCF consistently showed a stronger trade-off between RGR and MR compared to EBF. Generalized linear mixed models revealed that elevation influences RGR both directly and indirectly through its interactions with slope, crown competition index (CCI), and tree canopy height (CH). However, tree mortality did not show a significant correlation with elevation. Additionally, DBH significantly influenced both tree growth and mortality, whereas and CH and CCI had opposite effects on tree growth between EBF and TCF. Our study underscores the importance of elevation in shaping the population dynamics and the biomass carbon sink balance of mountain forests. These insights enhance our understanding of tree species' life strategies, enabling more accurate predictions of forest dynamics and their response to environmental changes.

Abstract :
As global forest areas decline and face increased risk from extreme events, optimizing forest types for long-term stability becomes crucial. However, empirical evidence for the effects of mixing methods on carbon and nitrogen dynamics in forest ecosystems remains limited. This study investigates five forest types in Southern China: the Tsuga longibracteata W.C.Cheng pure forests, the Tsuga longibracteata-hardwood mixed forests, the Tsuga longibracteata-Phyllostachys edulis (Carr.) J.Houz. mixed forests, the Tsuga longibracteata-Rhododendron simiarum Hance mixed forests, and the Tsuga longibracteata-hardwood-Rhododendron simiarum mixed forests (the tree species are all dominant community species). We examined one monoculture and four mixed forests, categorized into pure tree forests and tree-shrub mixed forests, and categorized by tree species richness levels of 1, 2, and 3. We measured carbon (C) and nitrogen (N) content, along with the C:N, of coarse woody debris (CWD) at various decay stages and in the adjacent topsoil (0-10 cm) to analyze decomposition rates and their effects on soil nutrients. Our results indicate that the C content and density of CWD differed significantly among forest types (p < 0.001). The Tsuga longibracteata-Phyllostachys edulis mixed forest exhibited the highest C and N content in CWD, but the lowest in adjacent topsoil, alongside the fastest decomposition rate. Soil C content and the C:N ratio showed highly significant differences among forest types (p < 0.001), and N content showed a significant difference (p < 0.05). Optimal outcomes occurred at a species richness level of 2, as excessive or insufficient species richness can diminish decomposition rates. The ecological benefits of tree-shrub mixed forests surpassed pure tree forests. Overall, these findings suggest that mixed forests do not always provide greater ecological advantages than pure forests, and that improper mixing can deplete soil.

Abstract :
Forest is the largest carbon sink on land, and the timing of forest phenology profoundly influences carbon uptake. However, disparities in the timing and sensitivity of forest phenology, particularly between planted forests (PF) and natural forests (NF), have yet to be determined. In this study, we analyzed the phenological trends and the climate-sensitivities of China's NF and PF from 2000 to 2022 using field survey data and satellite data. We found that the start of the growing season (start of the season (SOS)) in NF and PF advanced significantly by 0.07 and 0.08 days yr(-1), while the end of the growing season (end of the season (EOS)) in both NF and PF delayed by 0.06 days yr(-1). Moreover, precipitation and air temperature jointly influenced the timing of phenological events. The pre-season precipitation delayed the EOS by 0.009 days mm(-1) and 0.006 days mm(-1) in NF and PF. Moreover, the SOS was more sensitive to precipitation in PF than in NF in arid areas (i.e., pre-season precipitation <100 mm). Air temperature significantly advanced the SOS by 0.74 and 0.95 days degrees C-1 in NF and PF and delayed the EOS by 0.89 and 0.71 days degrees C-1 in NF and PF. Additionally, the sensitivities of SOS and EOS to air temperature significantly differed between NF and PF. Our findings demonstrate a significant phenological discrepancy between PF and NF. The results suggest that NF and PF responded differently to climate variability, implying forest origin should be considered in the projection of carbon sequestration capability under changing climate.

Abstract :
Forest carbon sequestration capacity in China remains uncertain due to underrepresented tree demographic dynamics and overlooked of harvest impacts. In this study, we employ a process-based biogeochemical model to make projections by using national forest inventories, covering approximately 415,000 permanent plots, revealing an expansion in biomass carbon stock by 13.6 +/- 1.5 Pg C from 2020 to 2100, with additional sink through augmentation of wood product pool (0.6-2.0 Pg C) and spatiotemporal optimization of forest management (2.3 +/- 0.03 Pg C). We find that statistical model might cause large bias in long-term projection due to underrepresentation or neglect of wood harvest and forest demographic changes. Remarkably, disregarding the repercussions of harvesting on forest age can result in a premature shift in the timing of the carbon sink peak by 1-3 decades. Our findings emphasize the pressing necessity for the swift implementation of optimal forest management strategies for carbon sequestration enhancement. The authors show China's forests can sequester 172.3 million tons of carbon per year in biomass by 2100, with an additional 28.1 million tons from improved management practices, but neglecting wood harvest impacts will distort long-term future projections.
