On the one hand, the presence of this network and its traffic flows offers accessibility and makes a contribution to economic development. While on the other hand, its presence and its traffic flows cause landscape fragmentation among national, regional and local scale. Since this year on, the government has declared the future national comprehensive development should be on the basis of sustainability in Taiwan. It’s the turning time for us to pursuit the dynamic balance among infrastructure, ecology and community all around the country. This research focuses on the effect of landscape fragmentation by rural road network. It does this by concentrating on presenting the method and formulae to qualify and quantify the resulting fragmentation of landscape pattern. Finally, the result of this research tries to integrate the concerning spatial concepts of accessibility and sustainable environment and to implement the “traffic calmed rural area” (TCRA) with some measures to merge the sustainable road network and to promote landscape connectivity in order to reduce the fragmentation effects in the expanding rural areas.application/pdf471163 bytesapplication/pdfzh-TW國立臺灣大學園藝學系暨研究所農村路網系統景觀生態格局景觀碎裂交通寧靜區景觀連結rural road networklandscape patternlandscape fragmentationtraffic calmed rural area (TCRA)landscape connectivity[SDGs]SDG8農村路網系統對景觀生態格局衝擊分析與評估reporthttp://ntur.lib.ntu.edu.tw/bitstream/246246/18237/1/922415H002026.pdf
