本研究針對六龜試驗林濱溪植群進行調查以了解該地區植群特性，提供未來森林生態系經營之有效參考依據。經由20個10×10平方公尺樣區內植物進行資料蒐集及分析後，結果顯示樣區內共計有147種植物及4種植群型，植群型的分化主要受到海拔高度的影響，由低海拔至高海拔度的植群型依序爲爲肯氏南洋杉植群型、九芎植群型、山香圓植群型、巒大杉植群型。主要優勢木本植物其族群結構多呈反J型，顯示在沒有明顯的人爲干擾情況之下，這些木本植物在該地區可完成自我更新。
The purposes of riparian vegetation investigation at Liukuei experiment forest were to understand vegetation characteristics for offering effective suggestion to develop forestry ecology management in the future. Plants within 20 plots in which each size of the plot was ten by ten square meters were investigated and analyzed. There were 147 species and 4 vegetation types basing on cluster analysis within all plots. The differentiation of vegetation was associated with altitude change. The vegetation types from low to high altitude were as follows: Araucaria cunninghamii, Lagerstroemia subcostata, Turpinia formosana, and Cunninghamia konishii. Most natural dominant woody plants showed anti-J shaped of population structure that indicated self-regeneration in situ can be completed without significant human being disturbance.
