英文摘要:The ethnic group of Hakka has remained its uniqueness in the aspects of their language, house, costume, folk customs, religious belief and habitual behaviors. The development process of these aspects is dynamic and continuous. In fact, the reclamation of Nanlong Tribe was guided by the Japanese, who led the Hakkas of Northern Taiwan, the Fukienese living in Gangshan, Tianliao and Cishan, as well as the local Hakkas of Meinong to take part in the reclamation. The interaction among different ethnic groups in the process of reclamation is worthy of making in-depth investigation. The research approaches of the paper include participant observation, interview and ethnographic studies. The paper further uses the spirit of constructivism to avoid any misunderstanding caused by different cultural backgrounds, hoping to employ an objective spirit to investigate the development process of Nanlong Tribe. The conclusions of the study are: 1. Nanlong Tribe is situated at a piece of gravel land, and flooding always occurs along Loanong River. Hence, the Japanese paid a lot of time and energy in the reclamation work, including the cadastral survey, forestry survey, construction of Jhuzimen Power Plant, and the flood prevention and control projects. 2. From the Japanese colonial period, the ruling period of Kuomintang to the present, the economic crops, including the sugar cane, rice, cigarette, banana, miscellaneous crops, etc. need more concerns and assistance from the government all through the period from their prosperity, decline to the existing transition. 3. The essence of the Hakka culture presented in the actual Hakka life, including the ways that the Hakkas respect the earth and heaven, worship their ancestors and previous generations, and defend the natural landscape of their hometowns, should be developed extensively. 4. The intermarriage among ethnic groups, the serious failure of handing down the mother language to the next generation and the remedial solutions, as well as the education and fostering of the next generation are the main problems to be solved urgently. The research results of this study can generally meet the objectives of the study, but there are still some unsatisfactory places. Thus, the study makes some suggestions: 1. The Hakkas should strengthen the proficiency of their dialect to help understand the quintessence of their tribe. 2. The time of actual participation in local life should be lengthened. 3. The researchers of this area should cultivate their reading ability of Japanese language to achieve further breakthrough in the acquisition of historical materials.
