In addition, the succession condition of local vegetation were also assessed to find out the environment conditions affecting the growth of vegetation, so that these findings may be used for accelerating vegetation succession and stabilizing the slopelands. The selected site was the Er-pa-zi Park, located in Xindion, Taipei county, Taiwan. The site was damaged by a heavy rainfall in June, 2004, and consequently mass movement occurred. Since the mass movement area was in the park, slopeland ecological engineering methods were implemented to reconstruct, so that the original vegetation and environment may be restored. In this study, thirty-six plots were set up and distributed in the site. Among the plots, fourteen were in the area rehabilitated by ecological engineering and twenty-two in the area of the adjacent natural forest. For all plots, twelve environmental factors were surveyed. After the analyses of the Two-Way Indicator Species Analysis （TWINSPAN）, Detrended Correspondence Analysis （DCA）, Matrix Cluster Analysis （MCA） and floristic composition, the results showed that the site had a high level of diversity and the Ficus fistulosa - Schefflera octophylla was identified as the primary vegetation type. It could be stated that after rehabilitation, the restored forest was similar to the adjacent natural forest, indicating that local vegetation was under spontaneous succession. Plant species distribution in the site was mainly affected by altitude, moisture and topography. The results also showed that restoration was more successful on the lower parts of the slope; accordingly it is suggested that more improvements are needed on the upper slopes.第一章 緒論 1 1.1研究背景 1 1.2研究目的 2 1.3研究大綱 4二章 文獻回顧 5 2.1生態工程—植生作用 5 2.2崩塌地生態工程案例介紹及其評估方法 7 2.3國內崩塌地植生演替 11三章 研究區域環境概述 14 3.1地理位置、地形及地質 14 3.2氣候與植生 16 3.3災害成因與復育整治工法 16 3.4 二叭子植物園邊坡穩定分析 20四章 研究方法 23 4.1資料蒐集與踏勘 23 4.2樣區設置及植群調查 23 4.3環境因子之計量與評估 25 4.4資料整理及分析 27五章 結果與討論 32 5.1初步調查資料彙整 32 5.2植物結構組成 34 5.3總樣區木本植物植群型 37 5.3.1雙向指標種分析（TWINSPAN）分類法 37 5.3.2降趨對應分析（DCA） 40 5.3.3矩陣群團分析（MCA） 42 5.4 植群變化與環境因子的關係 46 5.4.1全體樣區 46 5.4.2生態工程復育林 48 5.5植群演替推論 50 5.6生態工程之應用 50六章 結論與建議 54.1結論 54.2後續建議 55考文獻 56錄一、研究區域內植物名錄 60錄二、木本植物組成表 64錄三、木本植物資料矩陣 67錄四、環境因子資料矩陣 69application/pdf3811680 bytesapplication/pdfen-US坡地生態工程植群分析坡地災害評估植物組成二叭子植物園slopeland ecological engineeringvegetation analysisslope hazard evaluationfloristic compositionEr-pa-zi park[SDGs]SDG15thesishttp://ntur.lib.ntu.edu.tw/bitstream/246246/181180/1/ntu-97-R96622017-1.pdf
