博士 === 國立中興大學 === 園藝學系所 === 100 === Of all the current land development projects in Taiwan, Environmental Impact Assessment seems to be the only monitoring system when it comes to the maintenance aspect of ecological environment. Therefore, this study attempted to examine from the point of view of landscape ecology, identify the contents and role of landscape ecology professionals could participate in this system. This study explored land planning related studies and theories through literature review, in order to examine the possibility of using landscape ecology theories on large scale land development projects, including species move least-cost model, landscape structure index, species ecology assessment index, and landscape ecology principles, and then come up with a feasible operational process for subsequent development application. Based on numerous EIA reports from the past and through selection, this study has chosen Hsinchu Science Park Jhunan Science Park, Central Taiwan Science Park Taichung Science Park, Central Taiwan Science Park Houli Science Park, Southern Taiwan Science Park Tainan Science Park and Southern Taiwan Science Park Kaohsiung Science Park as the five study sites. When assessing of changes in bird species, we found that from diversity index and evenness index analysis, site development of Jhunan, Taichung, Tainan and Kaohsiung Science Parks have become more stable, and both indexes were either rising or constant. Both indexes of Jhunan and Tainan Science Park, which have better landscape structure or maintenance of ecological environment, appeared to be rising, and because Houli Science Park is still in the changing period of developing phase, the two indexes were very unstable and changes rigorously. Therefore, diversity index and evenness index are effective monitoring indicators in understanding whether if a site’s ecological restoration has reached equilibrium state, or if the site’s environmental structure is conducive to bird species habitat. Through the species move least-cost model of the five study sites, the possibility of examine from landscape sale is confirmed. In this study, Jhunan Science Park’s species move least-cost model changes were able to explain the disappearance of important habitat significantly affected large populations. Landscape changes in Taichung Science Park almost changed the original natural pattern entirely, and even it recovered through time and bird species were eventually stabilized, the composition, however, has tend to become ubiquitous species that are familiar to human. Although the pattern were changed in Tainan Science Park, the strategy of designated conservation area and integrity of greenbelt system allowed the recovered environment positively assisted in increasing the number and diversity of the bird population; but due to the limits of habitat environment, it is obvious that bird species were concentrated in certain areas. From these results, it is certain that species move least-cost model can predict ecological environment of a site, and it also is a viable tool for suggesting improvements. The results of landscape indicators are important data for planners to understand the landscape changes before and after a development. It can predict or verify the result of species change through the variation of aggregation and connectivity. Finally, actually carry out the original planning of the site according to the prepared procedure of this study, and at the same time under the condition of not affecting spatial function and building coverage ratio of the area, propose design recommendations for parks and green spaces. Because all the proposed recommendations are based on species move least-cost and landscape ecology principles, we believe these design policies will assist substantially in recovering landscape ecology, and provide enough ecological theory groundwork for EIA review.
