Abstract: The spatial distribution pattern of moso bamboo(Phyllostachys edulis)is generally limited by environmental conditions and self-thinning rule by itself. In order to understand the influences of the environment conditions and self-thinning rule on spatial distribution pattern, population dynamics, the productivity and quality of moso bamboo under the pattern of intensive farming, we sampled a 40 m×15.5 m plot on a mountain of Yongan City, Fujian Province, which was reckoned as a representative moso bamboo forest, used the heterogeneous spatial point pattern analysis method to check the distributional type of new moso bamboos in 2014 relative to old moso bamboos in 2008, 2010 and 2012, measured the spatial locations and the diameters at breast height(DBH)of moso bamboos, meanwhile used the generalized additive model(GAM)to check whether there was a relationship between the DBH of moso bamboos and the corresponding spatial locations. The results showed that the spatial distribution type of moso bamboo was random in a particular distance scale, and the DBH was significantly affected by the spatial locations of moso bamboo, which meant that the distributing environment of moso bamboo were heterogeneous. The biomasses of moso bamboo were related to environmental conditions, which implicated that it is important to improve the soil conditions and choose the plantation of moso bamboo for enhancing the productivity of moso bamboo and the quality of bamboo shoots. Thus, to use the inhomogeneous spatial point pattern analysis method is reasonable. The present study is of theoretical value for exploring the spatial distribution rule of moso bamboos, and it is also of practical value for operating moso bamboo forests.
