Abstract
The concept of Sustainable Development has been brought into the regional planning in Taiwan, but economic development is still the dominant orientation. Ecological resources are thus often to be degraded. Taipei-Yilan highway started its transport service in June, 2006. But few researches on the impacts of the highway and its following developments were done.
The construction of Taipei-Yilan highway has originated many other impacts on the environment of Langyang plain. The purpose of this study was to combine the land use pattern, ecological resources and spatial distribution in Lanyang plain to discuss the environment change on water resources, ecological resources, and landscape aspects. The LEDESS (Landscape Ecological Decision and Evaluation Support System) model was used in this study to simulate the impacts of Taipei-Yilan highway and its following developments on the regional ecosystems. According to the past environmental change and the future developing trend, four scenarios were designed and evaluated then in this study. Under the different scenarios and corresponding measures, the habitat of three chosen indicator species, Painted Snipe, American Golden Plover, and Kentish Plover, were simulated to understand the influence on habitat suitability. Conservation strategies were then proposed to recommend the favorable measures for future environmental management.
With the background of hydraulic engineering, landscape ecology and environmental resources were considered and integrated in this study. Based on the regional scale, the conversation between different fields has been created to form practical scenarios. The research is a multidisciplinary innovation.
