碩士 / 國立高雄第一科技大學 / 營建工程所 / 96 / Road construction leads to shortened distances between urban and rural areas and contributes to economic development and social progress. However, it has a harmful effect on the natural environment and landscape along the route. Together with rising income and broadening outlook, society’s road needs are no longer limited to attaining transport functions but widened to include considerations of landscape, environment, and ecological conservation as well. Trees by the roadside are very important for the design of road landscape. Through proper planning, they not only bring about better views and improved environments affected by traffic but also comprise green corridors that connect ecosystems in the countryside and cities, resulting in an overall upgrading of the surroundings and changing the image of roads for the better.
Through a study in the literature, this research compiled a list of ten factors that influence the effectiveness of tree planting in coastal areas: soil conditions, weather, location, suitable species, quality of sapling, transplanting, correct season, protection measures, and maintenance. A questionnaire survey of experts involving the analytical hierarchy process method was conducted to obtain the weights for each of these factors. Through statistical analyses, the four most important factors found are soil conditions (0.235), weather (0.190), location (0.082), and suitable tree species (0.210), having a total weight of 0.717. Then, based on the relative weights of these four factors, a fuzzy evaluation model was proposed. Real cases were used to illustrate the model and to establish the minimum acceptance score for tree planting in coastal highways, which sets a basis of effectiveness prediction and provides a reference for both designers and contractors in decision making for greening and landscaping.
