| With the rapid development of tourism, the domestic cities forest park, scenic areas are freeof charge to the public, more and more people into the ecological core area of the park, resultingin a serious impact on the Forest Park ecosystem service function. Nanjing Purple MountainNational Forest Park was chosen as a case study area, quantitative analysis of the tourismindustry (anthropogenic) effect on the scenic forest ecosystem service functions, exploringthe evaluation methods of open scenic affected by human factors, in order to put forward themanagement measures and suggestions for the sustainable development of scenic recreationalforest. The main results are as follows:(1)Due to the vegetation destruction, compaction, and soil erosion were caused byhuman activities such as mountaineering activities, and partly due to the invasion of alien species,wild plants around update layer is damaged. And with the natural succession of forest pest fieldscoupled with damage, forest growth recession, human disturbance is serious, the wild roadnearby soil damage is serious, the pioneer tree species such as Pistacia, cocobolo, Broussonetiapapyrifera natural succession is restrained, it is difficult to run smoothly.(2)In Nanjing Purple Mountain, the slope foot waist, top three area, the soil bulk density offorest land surface0.5m soil profile gradually increased from top to bottom; In thesame soil layer, soil bulk density gradually reduced with the increase of distance from wild way.The forest soil organic layer0.5m soil profile showing a reduced trend step by step from top tobottom; In the same soil layer, soil organic matter with the increase of distance from wildway and gradually increases.(3)A mountain beauty degree analysis showed that high purple mountain scenic beautydegrees are mainly distributed in famous scenic spots such as Ming Xiaoling Mausoleum, SunYat-sen’s Mausoleum and Linggu Temple. The forest landscape of low degree of beauty aremainly distributed in the outside of the Forest Park, the east city, the former lake, emperor gardenurban and rural residential areas. Hot scenic beauty degrees to an average of10.08, with anaverage diameter at breast height was22.69cm, an average elevation was88.96m, theaverage distance from the residential area was688.24m, the average distance from the road was255.23m. In contrast, the average cold spot scenic beauty degree was only0.04,with an averagediameter at breast height was only6.62cm, an average elevation was58.05m, theaverage distance from the residents area was340.21m, the average distance from the road was178.63m. The spatial distribution trend in Purple Mountain National Forest Park is themore closer to the core scenic area, the higher the degree of scenic beauty, the more close to theedge of the scenic beauty degree is lower, from the core to the edge, which in turn is extremelyhigh, high, medium, low, very low distribution pattern. The scenic beauty degree is positivelyrelated to the elevation of the location, and the roads, residential areas such as human factors interference was negatively related to.(4)In the aspect of improving countermeasures through ticket admission control distributionand mass media propaganda way to change the decision-making behavior of tourists to spreadpassenger flow; Strengthen the infrastructure construction of hiking; Protect scenic forestecological resources, strengthening the forest tending and seasonal landscape forest adjusting andoptimizing the several measures to improve the tourism activities such as effect on scenicrecreational forest ecological service function. |
