This study investigates the social transformation of Hung Mao Kang in terms of time and space. Not only the formation of regional characteristics of Hung Mao Kang, but also the dynamic process of the interaction between the people and environment of Hung Mao Kang is analyzed in this paper. Basically, the prohibition law of construction and settlement relocation policy are the very vital forces that have contributed to the isolated and failing vernacular landscape of Hung Mao Kang. The lack of administrative efficiency, the egocentric conservatism and procrastination mentality of govenments have resulted in chronic wrath of Hung Mao Kang residents. The population of Hung Mao Kang is not evenly distributed. Due to the compensation plan of the government, the number of registered household in this area has increased rapidly, particularly in the southern portion of the area. However, the increased number of registered household is misleading. As a matter of fact, the port functions and heavy industry of this area have brought vicious ecological consequences that not only drive the traditional fishery out of business, but change the economic structure of the area drastically. These ecological and economic changes have driven away the area's population. In spite of the change of economic structure and the decrease of population de facto, the social formation of the area is still strongly reflected in religious sphere of life. The societal cohesion and local identity is shown in people's efforts to institutionalize the maintainance of local historical and cultural relics. The identity and local historical and cutural relics will become symbols of the area even long after the settlement relocation implemented. Based upon the results of the present study, I have also designed a student-activity-oriented home geography teaching scheme, as the significance of home geography has increased in Taiwan.
