Abstract
       In southeastern Taiwan, vegetation plays an important role in rehabilitating badland soils (high silt and clay contents) and maintaining soil microbial community. The establishment of bamboo as the secondary vegetation could have produced a profound impact on the size and community structure of soil microorganisms in the soil.  However, very little is known about the influence of bamboo on soil biota in the badland ecosystem. The study was conducted in three badland sites in southwestern Taiwan, focusing measurement of phospholipid fatty acids (PLFA) together with soil microbial biomass C (Cmic) and N (Nmic) contents, enzyme activities, and denaturing gradient gel electrophoresis (DGGE). The size of whole soil microbes and bacterial and fungal groups as evident by PLFA contents and Cmic and Nmic were higher in the bamboo plantation soils than in the bare land soils. The greater soil organic matter in bamboo plantations largely explained greater size of soil microbial community. The lower of pH from alkaline also contributed to the increase in the size of microbial community in bamboo regenerated soils. Principal component analysis of individual PLFA peak separated the bamboo plantation soil from non-plantation bare land soil. DGGE analysis also revealed that change in both bacterial and fungal community structure between bamboo plantation and bare land soil. This can be attributed to bamboo suitable habitats and providing an essential nutrient source for soil microbes. The study demonstrated that bamboo plantation was beneficial for soil microbial activities and soil quality in the badland areas.
