摘要: | 道路對於經過地區的生態影響十分複雜,包括了地形、地貌、水文、大氣與土壤組成及鹽類(包含重金屬)的變動、噪音、光照、溫度、溼度……等環境因子。瞭解路邊植群經歷干擾之後的變化,可以由植群的現況以及歷史記錄來推估,本研究的目的,便是想了解臺灣的主要道路-高速公路,其路邊區域的植群變化。以國道三號(第二高速公路)為研究主體,調查路邊植群的現況,並且與1992-1993年的國道三號預定路線環境資源調查資料做比對,探討國道三號開發之後,路邊植群的變化。
結果顯示,路邊植群的組成,與氣候條件及通車時間有關。植物可用的水量越多和通車的時間越早,植群的組成越接近原始的植群樣貌。路邊植群已經遭到人為改變,而且道路的使用也帶來新的干擾模式。因此路邊植群的演替是否會繼續朝原有植群樣貌進行,或者是形成新的植群組成?則有待更多研究來解答這個疑問。 The effects of the road on the ecosystem are complecated. Facts include: the change of topography, landform, hydrological flow, the composition of air and soil, salts, noise, light environment, temperature, and moisture. We can speculate the change of the roadside with present vegetation and historical records. The purpose of this study is realizing the change of the roadside vegetation along Nation Expressway NO.3. I compare the survey data during 1992-1993, and field observation during 2005/7-2005/11 to analysis the change of vegetation after highway constructed The result of this study shows that the change of the roadside vegetation is affected by climate and timing of road usage. The composition of vegetation resembles more to the original vegetation composition with lesser conditions of water deficiency and earlier timing of road usage. The environment is already changed by human with new disturbances that came along with the expressway. Will the succession of roadside vegetation go back or reach to new composition? It needs more investigation to answer this question. |
