摘要: 生态化学计量特征是认识植物响应环境变化的一条重要途径。中国约有一半面积的毛竹Phyllostachys edulis林实施了集约经营，但关于经营水平对毛竹林生态化学计量特征的影响仍知之甚少。观测了粗放和集约2种经营水平对毛竹林叶片生态化学计量特征的影响。结果表明：集约经营显著提高了1 年生和3 年生立竹叶片的碳、磷质量分数及3 年生立竹叶片的氮质量分数（P＜0.05），增强了毛竹的碳同化能力和磷吸收能力。2种经营水平下，1 年生立竹叶片的碳质量分数均高于3年生立竹，而磷质量分数均低于3年生立竹。经营水平对毛竹林叶片的碳、氮、磷质量分数及碳氮比（C ∶ N），碳磷比（C ∶ P）和氮磷比（N ∶ P）均有显著影响，毛竹年龄显著影响了竹叶的碳和磷质量分数及C ∶ N和C ∶ P比值，两者的交互作用只显著影响了竹叶的氮质量分数和C ∶ N比值。试验区2种经营水平下毛竹林的生长均受到氮素的制约，施加氮肥可以促进该区域毛竹林生长，有利于积累更多的生物量碳。图2表4参26

Abstract: Studying ecological stoichiometry is an approach to understand the response of plants to environmental change. To determine management patterns and their effect on ecological stoichiometry with Phyllostachys edulis, an experiment was conducted by respective sampling to observe the effects of extensive and intensive management patterns on ecological stoichiometry with Phyllostachys edulis leaves for a stand in subtropical China. One-way analysis of variance （ANOVA） and least significant difference （LSD） tests were used to test the statistical significance of differences between two management types of plantations. Results showed that, compared to extensive management, intensive management significantly increased C and P content of leaves from both 1-year-old and 3-year-old bamboo （P＜0.05）, as well as N content from 3-year-old bamboo （P＜0.05）. Management level significantly affected C, N, and P content （P＜0.01） as well as C ∶ N, C ∶ P, and N ∶ P ratios of leaves （P＜0.05）; Phyllostachys edulis age also had a significant effect on C and P content as well as the C ∶ N and C ∶ P ratios of leaves （P＜0.01）. Meanwhile, the interaction of management level and age only significantly influenced N content and the C ∶ N ratio of leaves （P＜0.01）. Findings indicated that with the two management patterns, N limited Phyllostachys edulis productivity, and that increasing N by fertilization would facilitate growth thereby contributing to more accumulation of biological carbon.［Ch, 2 fig. 4 tab. 26 ref.］
