The Anion Resources Research In Tourism Area Of Anhui Province

With the development of the forest ecology tourism , this paper has studied the anion resources in different scenic spot of Anhui province. the main research place is in Mount Huangshan, and also include the Tiantangzhai scene district,Guniujiang scene district, we can conclude : the air anion density is abviously higher than it in other place , high density of anion is viewed a important tourism resources . this article has studied the density time and space change of air anion,the rule of the effect from different tree species on the anion. This text has also summarized the relationship of air anion with forest and evaluated the anion resources in different scene area.As a new kind tourism resources, the air anion distribution is different in different scene spot , the air ions seasonal change of the scenery district is notable, summer is the highest, spring take the second place , winter is minimum. The daily change law of air ion is : the density of air ion in morning is the highest, it falls at noon or in the afternoon .while it raises again in the dusk. By the actual observation, in summer , the density of air anion in Songgu and Diaoqiao scene district is the highest, it has over 30000 Num/ cm3,In beihai it reachs 18000 Num/ cm3,takes the second place. in Yungu scene district and Bailongtan , Renzipu of Wenquan scene district they are also reach 10000 Num/ cm3. in Xihai, Yupin and Tianhai scene district, it presents a kind of jumping change lever. the air anion density in winter is small, but still reach more than 1000 Num / cm3. In Bailongtan , Renzipu of Wenquan the ion density of spring exceeds 16000 Num / cm3; in Tiantangzhai and guniujiang the air anion is relatively steady, in spring of Tiantangzhai, the falls-- Xieyu's air anion reachs 20000 Num / cm3, in dragon peak it reachs 12000 Num / cm3, in the other places , the anion also reach 5000 Num / cm3, the anion total content is relatively high. In the Guanyintang scene spot of Guniujiang, the forest covering rate reachs over 97%, . in the air , the anion content reach 3000-8000 Num / cm3, Moreover , in different scene area , the anion density is higher than the positive ion. The vegetation has great affect on the air anion, for example, in Mount Huangshan, it has rich forest and the forest cover rate is high, the photosynthesis of the forest is strong and this produces a great deal of air anion, according to the experiment data, in winter, the contributing rate for the anion of conifer is 49.07%, the broadleaf is 12.49%. the anion density in the thin forest is higher than it in the dense forest. The Tiantangzhai and Guniujiang has many tree species and the anion content is rich. Moreover, in the scene area , the waterfalls has great effect to the air anion density, most anion density extreme value appears here. In Mount Huanshang ,Tiantangzhai and Guniujiang, the hydrology condition is very good, by means of testing ,the contribution of the hydrology to the density of anion is : falls is better than in stream , the flowing water has higher anion content than quiet water , the far away from the hydrology , the lower ion content existing. This experiment also has obtained the air anion content in different ion mobility level and the relationship between mobility and anion granule. By analyzing the distribution regular of the air anion in different scene spot . at last, we has researched the affection of height above sea level , the solar radiation ,the temperature and the moisture etc. so we could develop and use the anion resources further and sufficiently .In the forest tourism area there is a obvious preponderance of the anion resources in Anhui province. As it has became a new kind tourism resources in the developing of scenic spot , it has great sense to Anhui tourism. Protection of anion resources is the base of developing the tourism , and the ecology tourism will take the dominant position in the 21 century tourism .
