Conservation of Quercus hondae, an endangered species based on analysis of thier habitats and propagation traits

研究了红松的生态生理特征，提出了红松的保护策略。结果表明：1)常绿栎树的栖息地海拔最低；2)受资源和地形扰动的影响，它们在低坡和洼地上得以维持。3)人工针叶林的树密度与林龄密切相关，并受种子源有效性的影响。(4)与其他共优势种相比，红杉的生长对自身大小有较强的依赖性。5)红豆对光的光合响应表现出非先驱者特征，叶片与水分的耐旱关系较差。6)利用DEM和种子源分布信息在GIS上进行电位分布检测。

We investigated ecological and ecophysiological characteristics of Quercus hondaeto to develop conservation strategy for this species. The findings are: 1) Q. hondae has thier inhabitats in the lowest elevation among native evergreen oak species. 2) They successfully maintain on the lower slopes and bottomland, affected by resource and disturbance of the topography. 3) Tree density in artificial conifer forests of the species was strongly dependent on stand age, and also affected by seed source availability. 4) Q. hondae has strong dependence of their growth on their own size, compared with the other co-dominant species. 5) Q. hondae showed non-pioneer characteristics in terms of photosynthetic response to lights, and less drought-tolerant leaf water relations. 6) Potential distribution was detected on GIS by using DEM and seed source distribution information.
