Abstract
本試驗以人工模擬降雨裝置，模擬不同之降雨強度、坡度及延時下，探討覆蓋作物及敷蓋處理，對逕流與沖蝕產生之機制，及探求覆蓋與敷蓋處理對土壤沖蝕、逕流產生的影響。發現降雨強度、坡度及延時延百喜草覆蓋處理，除了對逕流率有增加之趨勢，對土壤沖蝕量則無影響，而逕流率隨降雨強度及延時之增加而增加，但所增加的量有限。
This experiment was carried out under rainfall simulator at Fengshan Tropical Horticultural Experiment Station. The purpose of this experiment is to study the effect and mechanism of cover crop and mulching treatment on soil erosion and runoff rate under different rainfall intensity, Slope degree and rainfall delay conditions The result showed that only runoff rate increased with Bahia grass treatment under different conditions.
