| Summary: | 碩士 === 國立屏東科技大學 === 森林系 === 92 === Tengjhih Forest Recreation Area is located at Bau-Shan in the Taoyuan District of Kaohsiung County, and comprised of compartment areas 70, 71 and 72 of Laonong working area, belonging to Pingtung District Office, Forest Brueau. 39 plots and 7 enviromental factors have been investigated and assessed. The correlation between plots and enviromental factors were analyzed by Cannonical Correspondence Analysis (CCA), Redundancy Analysis (RDA), and plant classification by Two-Way Indicator Species Analysis (TWINSPAN), Matrix Cluster Analysis (MCA) of the multivariate analysis method. The aims of this study are to find the significant factors to understand the relationships with plant communities and plant distribution.
The results show that there are 53 families, 110 genera, 167 species of species richness including 10 rare and endangered species. The most dominate families are Lauraceae, Fagaceae and Rubiaceae. The major enviromental factors affecting the distribution of plant and vegetation are altitude and lithosol of soil type. Vegetation types were divided into three major types and two subtypes of naturwald, including that 1. Callicarpa pilosissima－Machilus japonica type belonging to Machilus-Castanopsis forest zone. 2. Castanopsis carlesii type belonging to Quercus forest zone of which the stands in this study representing an ecotone, which could be divided by the microhabitat to (1) Cyclobalanopsis longinux－Elaeocarpus japonicus subtype, belonging to the upper part of Quercus forest zone, and (2) Symplocos stellaris－Litsea acuminata subtype belonging to the lower part of Quercus forest. 3. Castanopsis formosana－Glycosmis citrifolia type, belonging to Machilus-Castanopsis forest zone. Five forest types of plantation are: 1. Cryptomeria japonica forest type. 2. Taiwania cryptomerioides forest type. 3. Picea morrisonicola forest type. 4. Chamaecyparis formosensis forest type. 5. Chamaecyparis obtusa forest type.
