| Abstract |
As urbanization progresses, the need to preserve the city’s natural environment and ecosystem increases. However, because there was no standard for judging what to do to preserve natural environment and ecosystem in the city, policies were often made based on the intuitive decision by policy makers, which negatively affected the effectiveness of policies. Therefore, this study aims to develop an index for evaluating the soundness of the urban ecosystem and to find the means to establish objective basis for developing policy directions to preserve the natural environment of the city in the future by applying it to the city of Busan. In this study, the Ecological Health Assessment System of Busan was prepared based on existing methods and indicators for urban ecosystems such as the CBI(City Biodiversity Index). This evaluation system was prepared based on the PSR Framework, which consists of 3 pressure criteria, 9 state criteria, and 3 response criteria. The assessment of ecological health for Busan was conducted by comparing 2000s and 2010s to understand the recent changes of ecological health over the past 10 years. Based on this result, the study suggested improvement measures for natural environment policies. First, measures to improve input factors were proposed such as blocking citizens’ access to natural habitats outside the city, reducing light pollution and noise pollution, and preparing measures to reduce disturbance in the Nakdong River estuary. Second, as a way to improve the condition factors, preparation of quantitative standards for natural and semi-natural areas to be preserved, expansion of protected areas, establishment of early detection and control system for ecosystem confounding organisms, formation of a hub green for connecting disconnected habitats, selection and control of flagship species were suggested. Finally, the study proposed the need to secure budgets for green infrastructure deplopment, expand citizen recognition programs, and prepare a green governance system as a way of improving response factors. |
