该文目的在于揭示长白山森林沼泽生态交错带群落的演替规律 ,以便为科学地保护和经营管理森林与湿地过渡带生物资源提供依据 .选择本区典型的白桦沼泽生态交错带为研究对象 .采用定量观测和建立经验回归模型的方法 ,研究群落建群种白桦生长过程和斑块动态、蒸腾排水作用的相关规律 ,预测白桦沼泽生态交错带演替进程 .研究结果表明 :随着群落建群种白桦生长加快、年龄不断增大 ,林分个体着生的微域斑块呈现三次式函数曲线增大 ,林分蒸腾排水作用按幂函数曲线增强 .随着群落的发育 ,斑块不断扩大和生物排水作用的增强 ,白桦沼泽交错群落在 5 0～ 6 0a内将会使交错带生境趋于中生化 ,并演替为森林
The purpose of this essay is to reveal the succession rule of ecotone communities in forest swamps of Changbai Mountain in order to provide a scientific basis for the scientific protection and management of biological resources in the transitional zone between forests and wetlands.Taking the ecotone between the typical birch marsh ecotone in this area as the research object, Quantitative observation and empirical regression model were established to study the rules of growth and plaque dynamics and transpiration and drainage in the community-building species, and to predict the succession process of the ecotone between the birch and the birch. The results showed that with the establishment of community-based species Betula platyphylla grows faster and the age increases continuously, the curve of three-dimensional function of micro-domain patches of individual stands is increased, and the function of transpiration and drainage is enhanced by power function curve.With the development of community, Drainage enhancement, white birch swamp staggered community within 50 ~ 60a will make the ecotone zooplankton habitat, and the succession of the forest
