旅游干扰对蒙山植物种类组成的影响

2007年7月和2008年7月，采用典型取样法，调查了蒙山旅游区和自然区的植被种类与组成。在旅游区内记录到高等植物161种，其中草本植物99种，灌木40种，乔木22种；在自然区内记录到高等植物201种，其中草本植物117种，灌木57种，乔木27种。蒙山自然区植物群落以麻栎林、赤松林一麻栎林、日本落叶松一麻栎林等落叶林和针阔混交林为主；而蒙山旅游区植物群落以黑松林、油松林、赤松林等针叶林为主。蒙山旅游区植物群落演替滞后于自然区，旅游干扰对5m以外的植被影响明显。建议应继续清查蒙山植物资源，适当降低旅游干扰强度，严格保育自然林，及时清除外来入侵植物。

Effect of Tourism on Species Composition in Mount Meng Shandong Province

Plant species composition from the tourist area and natural area in Mount Meng were investigated ,using the typical sampling meth- od,in July 2007 and July 2008. In the tourist area higher plants 161 ,including herbs 99, shrubs 40, and trees 22 are recorded. In the natural area higher plants 201,including herbs 117, shrubs 57, and trees 27 are recorded. The plant communities in natural area are mainly deciduous forest and mixed conifer-broad leaf forest such as Quercus acutissima forest, Pinus densiflora-Q, acutissima forest and Larix kaempferi-Q, acutissima forest,while in tourist area are mainly coniferous forest like P. thunbergii forest, P. tabulaeformis forest, and P. densiflora forest. The plant community succession is later in tourist area than natural one. Tourism affects the vegetable far from 5 meters obviously. It is suggested that we should continue to grasp the plant resources in Mount Meng, reduce the tourist interference properly, strictly conserve natural forest and wipe away invasion plants on time.
