| Abstract: | This paper discusses the tourism disturbance on Fraxinus mandshurica community in Baotianman Natural Reserve area in Neixiang County,Henan Province. The results showed that under the disturbance,the soil porosity became lower,bulk density increased,soil organ content,total nitrogen content and active enzyme content decreased,while the total phosphor,total kalium changed a little. The results also showed that under the disturbance,the community had more species,flora became simple,the life form changed,and the Shannon-Wiener index increased in shrub layer but decreased in herb layer. |
