不同土地利用下土壤导水度探讨——以屏东科技大学为例

Soil Hydraulic Conductivity under Different Land Use Types-Case Study of National Pingtung University of Science and Technology

本研究主要是以Guelph渗透计于野外不同土地利用及不同深度下的水力传导度加以探讨,比较不同土地利用下土壤物理性质,结果发现土壤总体密度以牧草地最高,其次为裸露地,而竹林地为最低;p H值牧草地最高,其次为裸露地,竹林地最低;试验孔深度30cm及深度60cm的水力传导度皆为裸露地最大,最小为竹林地。

By using Guelph lysimeter, it is discussed the hydraulic conductivity on different land use types and different depths in the field for the comparison of the soil physical properties under different land use types.The results showed that, the pasture land ranked the top in the the overall soil density and pH value, followed by the bare land and bamboo land.While, the bare land ranked the top in the hydraulic conductivity at both 30 cm and 60 cm of test hole depth and the bamboo land ranked the lowest.
