生態都市永續發展已然成為目前之世界趨勢,但都市型態的發展會造成都市綠地使用型態的改變,人口急遽的增長以及都市無限制的發展與蔓延下,亦會減少生物所賴以生存的空間。都市正面臨著綠地不足,以及無法有效提升綠覆程度的困境,欲建構都市生態綠網的願景,便須從都市中提供之綠資源分布進行規劃與改善。 本研究在經由文獻回顧之後整理許多建構生態綠網的關鍵影響因子,並透過模糊德爾菲法及分析網絡層級法,進行兩階段專家問卷,以研擬出都市生態綠網評估指標體系,並以台中市進行地理資訊系統結合衛星遙感探測相關圖資的疊圖分析,進而提出都市適宜建構生態綠網的區位與改善建議。研究過程中,共取得23項評估因子項目。評估結果顯示,都市中綠資源應作為環境創造網路結點的功能,並創造更多都市綠資源,以增加網路結點,進而連結或加強都市現有綠資源分布區域,促進生態網路的形成,並可藉由都市屋頂綠化創造生態跳島能力,增進生態網路的連結程度,達到都市生態綠網的最大效益。
Sustainable development of eco-city has become the current trend in the world. But the development of city patterns will cause change in use of pattern of green space in the city. When the rapid growth of population and city development under the unrestricted and spreaded, it will reduce the survival of biological space. The city is facing a shortage of green space, and can not effectively promote a difficult position of the extent of green coverage. Therefore, to construct a vision of urban ecological green network, green resources distribution must be planning and improve efficiently in provided from the city. After reviewing the literature, the study finishing many of the key factors of construction of eco-green network. Through the Fuzzy Delphi Method and Analytic Network Process Method to practice the procedure of the two-stage questionaire survey into experts’ opinion. Attempt to structure a set of the evaluation indicator system of city ecological green network. The empirical investigation was carried out in Taichung City, analysis by Geographic Information Systems (GIS) combine with overlayed related-maps of remote sensing technology to obtain conclusions. Then to give propose and improvement for the suitable location of constructing urban ecological green network. In the course of study, there are 23 assessment factor projects were obtained. Results of the study revealed that green resources in the city should be created as a function of the environmental network nodes, and could also increase network nodes by creating more green resources. Then to link or enhance existing green resources where the region distribute in the city, promote the formation of ecological networks. Besides, it can also create capacity of ecological stepping-stone by greening roofs, and enhance the link degree of ecological networks. To achieve the maximum benefit of eco-green network in the city.
