摘要

碳(C)、氮(N)、磷(P)和钾(K)元素的循环过程在喀斯特森林的生态系统功能中起着至关重要的作用。对西南岩溶地区4个演替阶段的叶片化学计量特征进行了研究。生长期(2016年5月至6月)各演替阶段的氮磷含量通常高于衰老期(2015年10月至11月),但生长期的氮磷比低于衰老期,显示出明显的季节控制,符合生长率假说。在生长阶段,植物群落主要受氮含量的限制。在衰老阶段,从演替早期到演替中期的所有群落都容易受到N、P和K组合的影响,但从演替后期到演替高潮阶段,它们受到N、P和K组合显著的影响,并且在演替高潮阶段P限制更强。在每个演替阶段,比叶面积是影响叶片化学计量特性的最重要因素。这些结果表明,在生长阶段添加氮可以促进植被恢复和喀斯特森林生态系统的稳定。

Stoichiometric Characteristics of Leaf Nutrients in Karst Plant Species During Natural Restoration in Maolan National Nature Reserve, Guizhou, China
ABSTRACT The cycling process of carbon (C), nitrogen (N), phosphorus (P), and potassium (K) elements plays a crucial role in ecosystem functions of karst forests. The leaf stoichiometry characteristics in four successional stages are studied in a karst area, southwest China. The N and P contents in each successional stage are generally higher in the growth phase (May–June 2016) than in the senescence phase (October–November 2015) but there are lower N: P ratios in the growth phase than in the senescence phase, showing a clear seasonal controls and coinciding with the Growth Rate Hypothesis. In the growth phase, the phytocommunity is mainly limited by the N content. In the senescence phase, all communities from the early successional stage to the mid successional stage are prone to N limitation but they are significantly affected by a combination of N, P, and K from the late successional stage to the climax successional stage and the P limitation are stronger in the climax successional stage. The specific leaf area is the most important impact factor to leaf stoichiometric characteristics at each successional stage. These results indicate that nitrogen addition in growth stage may promote vegetation restoration and karst forest ecosystem stability.

期刊介绍: Journal of Sustainable Forestry publishes peer-reviewed, original research on forest science. While the emphasis is on sustainable use of forest products and services, the journal covers a wide range of topics from the underlying biology and ecology of forests to the social, economic and policy aspects of forestry. Short communications and review papers that provide a clear theoretical, conceptual or methodological contribution to the existing literature are also included in the journal. Common topics covered in the Journal of Sustainable Forestry include: • Ecology, management, recreation, restoration and silvicultural systems of all forest types, including urban forests • All aspects of forest biology, including ecophysiology, entomology, pathology, genetics, tree breeding, and biotechnology • Wood properties, forest biomass, bioenergy, and carbon sequestration • Simulation modeling, inventory, quantitative methods, and remote sensing • Environmental pollution, fire and climate change impacts, and adaptation and mitigation in forests • Forest engineering, economics, human dimensions, natural resource policy, and planning Journal of Sustainable Forestry provides an international forum for dialogue between research scientists, forest managers, economists and policy and decision makers who share the common vision of the sustainable use of natural resources.
