Abstract: 【Objective】To examine whether the biomass of moso bamboo(Phyllostachys edulis)in an ecotone is different from that of a non-ecotone.【Method】Study sites were selected on three mountains where an interface between moso bamboo and trees exists, and one mountain with only a single moso bamboo forest. Three plots were randomly chosen in either sampling belt in the interface and in the belt area, with 10 m distance from the interface below. The diameters at breast height(DBH)of moso bamboo on the sampling belts were measured, and the relevant soil nutrients were analyzed. The Kruskal-Wallis statistic was used to test whether there was a significant difference in the mean DBH of moso bamboo between two sampling belts(i.e., the interface and the belt area below).【Result】The results showed that: ① The biomass of moso bamboo in the three landscape ecotone types was significantly higher than that in the moso bamboo plantation, especially in the upper transects, biomasses were 11.09%-27.72% higher at the same altitude in the ecotone transects than that in the plantation transect. The biomass in the upper transects of landscape ecotone types was higher than that in the lower transects, in contrast to the results for the moso bamboo plantation. ② The differences were significant in two transects of the three types of landscape ecotone, but not significant in the moso bamboo plantation. ③ There were no significant differences in soil nutrients between two transects of the four mountains. However, there was an overalltrend of soil nutrients in upper slopes being lower than those in lower slopes, contrasting the trend in transects of moso bamboo biomass in the three landscape ecotone types.【Conclusion】Landscape ecotone has a positive effect on the biomass of moso bamboo, and different landscape ecotone types have significant effects on the biomass of moso bamboo. However, the extent of these effects was different. Regardless of the level of soil nutrient content, the biomass of moso bamboo in three types of landscape ecotones was higher than that of the moso bamboo plantation owing to the effects of stand type, stand structure, and human management policies.
