淡水河口濕地景觀資源評估－以挖子尾自然保留區為例

本研究以視覺景觀美質評估的角度來探討河口濕地景觀，並以具有多樣景觀資源特色的挖子尾自然保留區為研究區域，由景觀評估方法、因子分析及複迴歸分析評估研究區內之景觀資源。因子分析結果顯示挖子尾自然保留區景觀型態主要為（1）河岸灘地景觀型態（2）河灣船舶景觀型態（3）紅樹林景觀型態（4）碼頭灘地景觀型態。分析景觀元素與景觀美質評值相關性時發現船隻面積、近景綠帶與第一次，第二次評值呈現正相關的趨勢，灘地則是呈現負相關的情形。複迴歸分析結果指出景觀組成元素影響景觀偏好程度依序分別為船隻、遠景綠帶、遠景山脈、天空、近景綠帶、水體、道路、灘地、遠景建築，表示船隻數量的變數，可能有提高景觀美質的效果，遠景建築則可能有降低景觀美質的作用。另由相關分析檢定可發現，第一次評估與第二次評估結果兩者間具有顯著正相關，顯示景觀美質評估方法具穩定性，此方法可真實的反應受測者對河口景觀美質的偏好。

The main purpose of this study is to evaluate the estuarine area landscape of Waziwei natural reserve area at Tanshui River by using psychophysical model, landscape assessment methods, factor analysis and multiple regression. The factor analysis results indicated that the landscape types of this natural reserve are coast, boat, mangrove and harbor landscapes. The multiple regression model displayed that the importance of landscape elements on the preference are boat, faring greenway, mountain, sky, nearing greenway, water body, road, intertidal, and faring modern building, respectively. Moreover, modern building has negative impact on the scenic beauty value of this study area. The nearing greenway and boats have high positive relation with first and second evaluations. On the other hand, intertidal has negative correlation with these two evaluations. The results also displayed that the correlation of two evaluations is highly significant. Finally, these landscape assessment methods are consistently presenting the estuarine area preferences of the testers.
