摘　　要：为了解明月山旅游活动对建群种群的影响,采用T-square距离方法研究了明月山马尾松种群的空间分布格局。结果表明:海拔400 m、700 m和1 500 m的马尾松种群空间分布格局为集聚型,海拔1 000 m和1 300 m马尾松种群的空间分布格局为随机型。马尾松种群空间分布格局随着海拔高度发生规律性变化。说明,明月山的旅游开发活动已对低海拔的种群产生一定干扰。因此,应制定合理的明月山开发保护规划,促进明月山旅游开发的良性发展。In order to study the effect of the tourism activity on the dominant population on Mingyue maintain.The spatial pattern of Pinus massoniana is studied by T-Square method.The results showed that the population at the elevation of 400 m,700 m and 1 500 m was in aggregated distribution,but in random distribution at the elevation of 1 000 m and 1 300 m.Such conduction could be drawn that the spatial pattern of Pinus massoniana change with latitude.The vegetation was affected by the tourism activity on the foot of the mountain.So it is essential to rationally plan for the development and protection and promote sound tourism development of Mingyue mountain.
