Research Of Forest Recreational Impact On Soil And Vegetation And Recreation Carrying Capacity Of Mountain Tai National Park

Method of after-the-fact analysis was used, and status of forest recreational impacts on vegetations factors and soil physics-chemistry characteristics in Mountain Tai National Park was researched. On the base of investigating and analyzing, and using the theory of Tourism Environmental Bearing Capacity, regularities of time-space distribution about the tourism demands and Tourism Environmental Bearing Capacity of different scenic areas were evaluated, and strategies of environmental controling and management for sustainable development of Mountain Tai National Park was putted forwards. The results of qualitative and quantitative analysis are as fallow:1. The recreational impacts on soil physics-chemistry characteristicsThe recreational impacts on soil physics-chemistry characteristics has a high central character, appeared a shape of"Dot","Line"and"Broad Surface". The recreational activity caused the thickness of litter and humus layer soil water content and the soil pH decreased,and soil hardness increased. The of recreational impacts degree faded with the increase of distance away from the footpath or scenery spots, and then become stabilization when the distance exceeded a certain quantity. The range of soil impacted in the four scene districts were 3m, 2m, 1m and 1m. The degree of recreational impacts on soil was coincident with the tourism number, with an order of: Heaven scenery zoneï¹¥The south fringe of Mountain Tai scenery zoneï¹¥Heaven Candle Peak scenery zoneï¹¥Fan Cliff scenery zone.The soil factors had no significant relation with geography characteristics, and the impact had the trend to occur in sunny, flat and low elevation area, the trampling index had negative relation with soil character factors. 2. The recreational impacts on vegetationsThe recreational impacts on arbor were less than that of shrub and herbage. The abundance was more impacted than the species quantity, height and the update degree. The Impact Value Index in the four scene districts were 40.39%,34.37%,31.03% and 32.31%, with an order of: Heaven scenery zoneï¹¥The south fringe of Mountain Tai scenery zoneï¹¥Heaven Candle Peak scenery zoneï¹¥Fan Cliff scenery zone.The vegetations factors had no significant relation with geography characteristics, and recreational impacts had the trend to occur in sunny, flat and low elevation area, the trampling index had negative relation with species diversity, vegetation coverage and vegetation height, the tourist amount had significant positive relation with cover reduce, floristic dissimilarity and impact value index.3. The regularities of time-space distribution and the calculate of Tourism Environmental Bearing CapacityThe regularities of time-space distribution about the tourism demands were noticeable. The recreational time centralized on April to October, the recreational space centralized on Middle-Road. The Day Tourism Environmental Bearing Capacity was: TEBC (summer) = 16250 P/D; TEBC (winter) = 9920 P/D, the Year Tourism Environmental Bearing Capacity was4.2 million.Some creations were made.1. It was the first time to use the ecological theory to research forest recreational impacts on vegetations factors and soil physics-chemistry characteristics in Mountain Tai National Park.2. The relation between recreational impact and soil-vegetation factor was researched, it made the content system more perfected and the results more scientific.3. The traditional research methods were mended, the recreational impacts and the regularities of time-space distribution were combined, it made the results more practicality.4. On the base of investigating and analyzing, strategies of environmental controling and management for sustainable development of Mountain Tai National Park was putted forwards.
