A case study of legal mechanism for controlling the land use in Taipei Water Source Domain
  
  
Taipei Water Source Domain (TWSD, 台北水源特定區), providing water supply for great Taipei region, is also expected to offer ecological habitats. People argue that the land use which is controlled by redundant legal mechanism (including agencies and regulations) directly affects the land cover types (LCTs) in this area.
This article concerns the fragmentation of ecological habitats and expects to clarify the impact resulted from the legal mechanism. As a typical descriptive case study, we focus on this question: (how) does legal mechanism of land use work? There are two following questions to concentrate our concepts: how do agencies share the responsibility to control the land use and how does the habitat fragmentation reflect the land use regulations.
We establish a theoretical framework to analyze the legal mechanism of land use in the freshwater protected areas. We collect the data through two approaches. The first one is to search the relative legal articles in Laws and Regulations Database of The Republic of China (全國法規資料庫). More than 20 laws/regulations and hundreds of articles are applied. The second one is to digitalize the aerial photos and select a sample of 50 sites to calculate the metrics of landscape fragment.
Based on our theoretical framework, we answer the research questions with the efficiency of the legal mechanism. First, the legal regulation of land use could work through critical punishment, no matter what the agencies are. Next, the legal mechanism prevents the illegal private development and behavior successfully, but fails to stop the existing development. The final finding is the legal mechanism indistinctly encourages the over-developing of local public sectors.
