【摘要】 本文以营养动力学思想为指导,应用野外观测与室内实验分析相结合,定性分析与数学模型相结合的综合研究方法,研究了红松(Pinus koraiensis)的营养结构与动态,光合作用及其变化模式,营养空间与生物生产力,年龄结构与周期性波动,以及幼苗的分布格局。以营养关系为基础,对红松和阔叶树种的生态位分化进行了研究。为经营和发展阔叶红松林提供了依据。更多还原

【Abstract】 According to the theory of trophic dynamics a synthetical method that the field observations combined with the laboratory analysis and qualitative analysis combined with mathematical models, were applied. The trophic structure and dynamic, photosynthesis and its patterns, t- rophic space and productivity, age structure and the periodic fluctuate, and the distributional pattern of korean pine seedlings, were studied. The differentiation of the niche between korean pine and broad-leaved trees was also studied here. It is provided to be a scientific basis for the management and development of korean pine forests.更多还原
