Item 高屏溪谷與潮州斷崖沖積扇的地形學研究(地理學系, 1995-10-??) 張瑞津; 石再添; 楊淑君; 林譽方; 陳翰霖; 董德輝Kaoping valley and Chaochou fault are lecated the southwestern part of Taiwan Island. With conspicuous fault scarps and abundant debris supply, alluvial fans are developed well in this area. There are 38 fans with area over 0.1 km each, 22 of them are distributed in the Laonung valley, 8 of them in Nantzuhsien valley, and the rest are in the piedmont along the Chaochou fault scarps. In the valley, most of the fans have been undercut to be composit fans. The fact of the fan head trench shifting down could reveal that the down cutting rate of stream channel is greater than the uplift rate of mountain area. By product-moment correlation, some fan variables are correlated closely, such as fan area has a significant relation with length, width, slope and roundness of sediments. Based on the discriminant analysis, the precipitation, geological period, the stream length, hypsometric integral and relief ratio are the dominating factors to the existence of the fan. By factor analysis, drainage area, uplift rate, relief ratio, geology of drainage basin, drainage length and evolution stage of fan are the main factors influencing the fan morphology. From the relation between fan and drainage basin, the evolution of the fan of the Nantzuhsien valley and Chaochou fault can be interpreted by the equillbrium model.Item 臺灣花東海岸海階的地形學研究(地理學系, 1988-03-??) 石再添; 鄭國雄; 許民陽; 楊貴三This paper is the first year report of the research project “A Geomorphological Study of Marine Terrace in Taiwan”. The Huatung coast is along the Pacific coast of Eastern Taiwan, adjacent to the convergent boundary of Eurasia Plate and Philippine Sea Plate, marine terrace is typically developed in this region. Based on air photo interpretation, geomorphometry, field excursion and accurate survey of altitude, the results are summarized as follows: 1. Classified and correlated by the continuity of altitude and extend of the marine terrace surfaces, there are three dominate marine terraces in study area. The flights of marine terraces in the southern part are comparatively more widely distributed than in the north, the lowest one and the newly raised wave-cut platform are well developed throughout the study area. 2. Altitude of terraces in the southern part is obviously more higher, expecially in the upper two steps, showing that there are wave-like uplifted and tilted slightly to the north. Yet the lowest steps together its newly raised wave-cut platform have almost the same height throughout the study area, this implies that recent uplift rates are progressing with equal amount, and in the upper steps, the tectonic movement has the property of accumulation. 3. The displacement of terrace surfaces is observed as a short-wave length warping, upwarping has been taken place with the axes in the vicinity of Chanping, Chengkung and Tulan, the distance between the axes is about 25 to 30 km. 4. The third steps are furnished with multi-levelled terraces, at intervals of 2-5 m in elevation, deduces from the mode of seismic uplifts in the neighborhood, those multi-levelled terraces may originated by the co-seismic uplift. 5. The features of marine terraces are also influenced by geological setting, in the area of more?resistant rocks, marine terraces are very narrow and covered with thin marine boulders, coastal landforms such as wave-cut benItem 臺灣北部河口地區之地形學研究(地理學系, 1996-11-??) 石再添; 張瑞津; 林雪美The vincinity of the estuaries is one of the most populated area in the world. In order to ultilize the resources of this area more reasonably, the understanding of geomorphological, hydrological and sedimentary characteristics becomes a fundamental task. Since estuary is located on the interface of river and sea, its morphology is influenced by the factors coming from both environments. The drainage basin area, shoreline length, shape factor, channel gradient, runoff, sediments and monthly discharge, etc. are the factors from land, while the wind, current, wave and tide etc. are the factors from the sea. This study focuses on the 19 estuaries of the northern coast of Taiwan. According to the principal process of estuarine area, these estuaries can be classified as fluvial, tidal or wind wave dominated type. Based on the field observation, the depositional forms of these estuaries have significant seasonal change due to the seasonal differences of river discharge, wind, tidal range, wave and typhoon freqency. On the other hand, the result of the comparison of six sets of topographical maps from 1904 to 1989, shows that the seaward and landward migration of most estuaries is unstable.Item A Geomorphological Study of Active Fault in Northern and Eastern Taiwan(國立台灣師範大學地理學系, 1984-10-??) 石再添 張瑞津 黃朝恩 石慶得 楊貴三Item Geomorphology of the Alluvial Cones near Huoyenshan, Central Taiwan(地理學系, 1990-03-??) 黃朝恩本論文的研究目的，乃以計量方法，針對台灣中部火炎山地區的沖積錐群，作詳細的地形計測、航照判釋，野外調查與粒度分析，實地探索此等地形有關形態特徵及沉積環境的許多問題。全文分為四個部分：首先介紹了沖積錐群及伴生的火炎山景觀之位置、範圍及外貌；接著闡明沖積錐的幾何形態及其營力制約；再其次著重討論構成該地形的沉積物及其各項結構參數，如粒徑、粒形和組構等，當中更採用卡方檢定和曼惠尼檢定等計量方法加以分析，以期將此一具有獨特性的沉積環境作深入及量化之掌握。最後，更把其他相類似的營力和沉積成果展現作一比較，藉以提供值得繼續研究的學術題材。Item 臺灣北部海岸沙丘之地形學研究(地理學系, 1992-03-??) 石再添; 張瑞津; 林雪美; 張政亮; 連偵欽Item 應用地形學之概觀(師資培育與就業輔導處, 1988-04-??) 張瑞津Item 海岸山脈東坡河階的地形學研究(地理學系, 1991-03-??) 張瑞津; 石再添; 曾正雄; 高鵬飛; 陳美鈴Owing to the continuous uplift since Quaternary, rejuvenated terraces, gorges and raised alluvial fans are developed well in the eastern slope of Coastal Range. The river terraces in this area are distributed below 200 m generally. The scarps of higher level terrace are larger than that of lower level one. The gravel deposits in higher level terrace are thicker than that of lower level one. Comparing the terrace between six studied rivers, meander terraces are significant both in Mawuku River, Fengpin River, Shuilien Riverand Fanshuliao River whereas fan terraces are developed well in Sanhsien River. In contrary, the terrace in Shuimuting River is undeveloped due to down cutting into hard rock which restricts the widening of terrace. By correlating to marine terraces, most of the terraces in this area are formed in Holocene. The detailed correlation of each step or dating still needs more envidences.Item 新店溪河階之地形學研究(地理學系, 2000-11-??) 張瑞津; 鄧國雄; 劉明錡River terraces including six lateritic surfaces (LH、LT1-LT5) and three non-Iateritic surfaces (FT1-FT3) have been recognized along Hsin-tien River. Most of lateritic surfaces distributed concentrately at Ping-lin, Shen-chang-Pan and Hsin-tien. Comparatively speaking, surfaces LT4, LT5 and FT2 distributed more widely and continuously than the others. Under the effect of tilting, the channel tended to shift from south to north and became sinuos. Sinuosity increased to the maximum in the LT4 stage that imp1ied the river had a significant lateral erosion in relatively stable stage. FT terraces have been formed under the controlling effect eustatic fluctuation and subsidence of Taipei Basin. The meander cut occurred during the lowering base level stage (FT1-FT2). Referring the results of climatic and eustatic fluctuation, the LT5 and three FT surfaces have been formed respectively in high sea level around 40000, 10000, 6000 and 3000 years before present.Item 臺灣西部海岸沙丘之地形學研究(地理學系, 1993-06-??) 石再添; 張瑞津; 張政亮; 林雪美; 連偵欽Coastal sand dunes are widely distributed along the western coast of Taiwan from Touchien Hsi to Erhjen Hsi. Based on maps work, airphoto interpretation, particle size analysis, field investigation, etc, the study results are summarized as follows: 1. The form and the magnitude of the western coastal sand dunes have close relationship with the source of 13 rivers' sand supply, alongshore current and wave action, power and direction of wind, terrains, rainfall, evaporation and vegetation. 2. The coastal dunes develop well on riversides of Chung Kang His, Holung Hsi, Choshui Hsi and offshore bars along Chianan coast. Two principal types of these dunefield may be distinguished, namely, active dunes and stabilized dunes. The two dunefield types contain a variety of dune features, such as transverse dunes, barchans, longitudinal dunes, and dome dune etc. 3. The grain sizes of beach and dune sand are quite uniform. The Md φ and δ φ on average of the dune sand is smaller than the beach sand. This shows that wave process is stronger than wind process. 4. Comparing the maps published in 1926 and 1984. the change of coastal dunes is clear. Because the dunefield was used as fishery or watermelon and sugarcane planting, most of the sand dunes were leveled off entirely. Some of the residual sand dune still exist at present fixed by windbreak forest. For sand dunes have the function of protecting coasts, they had better be well-planned and well-used so as to main-tain the sustainable utilization of land souces.
