摘要

鄉村生態綠網計畫是以改善鄉村生態環境為基本意義，而都市生態綠網與週遭鄉村綠帶系統的連結，更是有緊密的相依關係。從區域生態綠網的角度上檢視，鄉村與都市的生態綠網建構，應該是併行實施以維持整體區域景觀及自然生態環境的完整性。本研究以農業社會為主的鄉村地區作為景觀格局分析地點，並從景觀生態學的觀點，探討鄉鎮間具生態保育功能的綠帶與其連結關係。透過研究地點土地使用類型與實際現況了解，以GIS為景觀格局分析之基礎平台，輔以景觀指數分析軟件Fragstats，根據分析結果，除檢視景觀破碎化程度之外，從計畫之層級檢討生態綠網觀念下，基於生物多樣性的理念，基地可行的生態廊道配置方式。
由研究結果顯示，在鄉村生態綠網計畫觀念下，研究範圍內如藉由設置河川廊道或是道路緩衝帶，除了綠帶面積增加外，從景觀指數計算結果中顯示，整體樹林類塊區在破碎化與連接度上有相互影響的現象，且在研究範圍的地理條件下，道路緩衝帶的設置反而減弱了塊區間的連結現象，而以河川廊道設置及道路緩衝帶與河川廊道的相互連結這兩個方式為最能提高整體連接度。

The basic meaning of rural ecological green network plan is to improve the rural ecological environment, and the combination of city ecological green network and the nearby rural green system has much closer relation. To view from the area ecological green network part, the construction of city and rural ecological green network should be work together in order to maintain the completeness for the landscape of whole area and its natural environment. This research takes the rural area which mainly base on the agricultural society as the analysis place of landscape pattern. Also from the landscape ecology point to discuss the link relation between the villages and towns which are attached with the greenbelt of ecology care function. To understand it by the use type of land and the real situation on the study places. Taking GIS as the basic platform of landscape pattern analysis, and then assisted by the landscape metries analysis software named Fragstats. According to the analysis result, except to check the level of landscape fragmentation, also review the ecological green network concepts under the plan. And base on the biodiversity idea, the workable way for ecology corridor on the foundation.
From the landscape metries data shows if we set up by the stream corridor or road buffer under the concept of rural ecological green network plan. It not only increases the greenbelt, but the whole forest patch has influenced each other between fragmentation and the connection, which also revealed on the calculation result of landscape metries. And under the geographic conditions of the research, the establishment of road buffer reduces the connection among those patches. So to set up stream corridor and join together with road buffer, these two ways can most enhance the whole connection.
