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.

我们调查了洪多奎尔森山的生态和生态生理特征，以制定该物种的保护策略。研究结果是：1）Q. hondae在天然常绿橡树物种中的居民处于最低海拔。 2）他们成功地维持了下部斜坡和底层，受地形的资源和干扰影响。 3）该物种的人造针叶树林中的树密度很大程度上取决于陈列年龄，也受种子源可用性的影响。 4）与其他共同主导的物种相比，洪多的生长对自己的规模具有很强的依赖性。 5）洪多的Q. hondae在光合作用的反应和耐旱的叶水关系方面表现出非偏位特征。 6）通过使用DEM和种子源分布信息在GIS上检测到潜在分布。
