The Study On Landscape Quality And Recreational Carry-capacity Of Scenic Recreational Forest In Mountain Tai

As an important natural aesthetic resource,forest landscape is a basis of forest park constructing and ecological tourism developing. The research is conducted on relationship between forest landscape resources and aesthetic quality from aspects of spatial structures,types and elements of forest landscape,and the landscape quality and recreational carry-capacity of scenic recreational forest was studied on the basis of evaluating on ecological functions and aesthetic valuation in Mountain Tai which belonging to the world cultural and natural heritage. The aims are to provide the theoretical and practical basis for scenic forest management and tourism development. The results as follows:1. The geographical landscape resources, hydrological landscape resources, biological landscape resources, cultural landscape resources, astronomical landscape resource, region environmental quality and tourism developmental conditions were evaluated comprehensively according to the national standards. The score of evaluation was 43.02. Therefore, Mountain Tai tourism areas accorded with the landscape resource standard of first-class.2. Ecological quality evaluation of scenic recreational forest in Mountain Tai was studied in analytic hierarchy process. The result shows that biodiversity has the most restriction to ecological quality, and other factors have some influence on it. Comprehensive score of Mountain Tai is 0.831, so it has a better ecological quality.3. The result of aesthetic valuation of scenic spatial structure indicate that coniferous forest is the dominant landscape with many types of landscape that form dispersal patch structure in Mountain Tai. The basic structure consists of big patches with high landscape richness index and landscape diversity index, with low landscape fragmentation and landscape dominance index. These characteristic indices supply plentiful aesthetic and tourism resources.4. The aesthetic evaluation of landscape types shows that the scenic beauty sequence of forest vegetable types is ancient tree>forest in the cliff> mixed forest of larch and alnus> forest of Acer mono >forest of Robinia pseudoacacia> coniferous forest>forest of Quercus spp.> shrubbery. The aesthetic assessment of landscape elements shows that the main elements affecting the aesthetic quality of coniferous forest are the form of trunks, diameter at breast height, color variation, the unitize degree of the under storey and litter. Trunk straight,big breast height diameter, plentiful color variation and high unitize degree of the under storey do good to scenic beauty, while more litter do harm to scenic beauty.5. From the result of environmental carry-capacity analysis we can see that the reasonable environmental carry-capacity is 4.28 million persons per year, but the number of actual tourist is 2.8 million, so the tourist number has not been well optimized.According to the results of assessment, it is advised that strengthening the protection of existing landscape forest resources ,i.e. in the premise of protection to exploit and to use the landscape resources properly, and enhance their richness and diversity, improve ecological function stability. Besides, aiming at the characteristics of hydrology resources' lack, it should strengthen their protection and exploitation usefully in the aspect of landscapes' management, something must be done to cultivate large diameter tree gradually, regulate the density of forest trees reasonably, mixed forest forestation, protect the ancient and famous trees in the aim of improving the quality of landscape.
