Chinese Abstract

植生依賴於土壤而得以生長,土壤受植生保護而減緩流失,植生與土壤相輔相成,方能保育水土資源。本研究調查十五處塌地樣區,遍及苗栗、台中、南投、嘉義等縣市,以崩積土和石質土占多數,土壤質地以壤土為主和少部分的砂土。植生的處理方式有自然生長、鋪網噴植、打樁編柵、人工栽植及撒播等工法。部分地區土壤中石礫含量偏高,九份二山堆積區地表大多為礫石。土壤總體密度介於0.82~1.81g/立方公尺之間,pH值介於3.5~8.17之間,有機質含量介於0.29~6.71%之間,九份二山順向坡崩塌區岩盤裸露,植生不易,所以覆蓋率為所有樣區中最低之處。植生初期之生長受土壤性質影響甚大,石礫含量太高之處,植生生長不良。裸露坡面經過植生後,土壤總體密度明顯下降,有機質含量明顯增加,改善了植物生長的基盤,有利於日後植被的生長。

English Abstract

Vegetation growth relies on the soil, but soil by vegetation protection to reduce erosion. This study investigated 15 landslide areas which distribute in Miaoli, Taichung, Nantou and Jiayi. The colluvial soil and lithosol are majority in these areas, and the major soil textures is loam. In these areas, Chiu-fen-er-shan has higher gravel content than others. Soil bulk density is between 0.82 and 1.81 g/cm^3, pH is between 3.5 and 8.17, and organic matter content is between 0.29 and 6.71%. The steep slope in Chiu-fen-er-shan has lowest vegetation cover rate. Soil properties affect vegetation growth greatly in initial period. Soil bulk density decrease, and organic matter content increase obviously after vegetation. These changes improved the matrix of vegetation growth, and will be advantageous to vegetation growth in the future.
