A Research On Tourism Resource Of Negative Air Ion In Shennong Gu National Forest Park

Negative air ion which is known as the "air vitamins and auxin" can kill bacteria,clean up dust and clean air. Negative air ion is essential to life and very beneficial to human body health. Its level has become an assessment index of air quality.Many scholars has studied on the distribution discipline of negative air ion in forest environmental,but due to the close relationship between negative air ion and its surrounding environmental factors,and its distribution discipline has spatio-temporal difference,so the research results are also different. Shennong Gu national forest park forest owns rich resources,the forest ecosystem influenced by geography, climate, hydrology, soil and terrain of many kinds of factors in the long succession process formed its unique forest ecological environment type. At present, the research on the distribution discipline of negative air ion in Shennong Gu is still lacking.The forest can produce abundant negative air ion because of its unique forest microclimate,and that the forest has higher negative air ion level has been confirmed by many institutes. People have realized that negative air ion is a kind of invisible, high-tech, important forest tourism resource.Researching on the distribution situation of negative air ion of Shennong Gu national forest park has important practical significance for its correct development and construction,reasonablely exhibiting forest tourism and guiding the developing of negative air ion which is a very important ecotourism resource.This paper choosed Curtain Fall and Horn Ridge which are the most important two representatives of Shennong Gu as research object,and studied on their distribution discipline and the relationship between negative air ion and its impacting factors.The main purposes are following:(1)providing theoretical basis for the utilization of negative air ion resource of Shennong Gu;(2)providing scientific guiding for people to go in for forest tourism;(3)providing the basis for urban landscape planning and construction and realizing the good living environment;(4)providing references for the further study on negative air ion.The results showed that the negative air ion of Shennong Gu takes on a kind of variation discipline:(1) The negative air ion concentration,air ion polarity ration and air quality assessment index of Shennong Gu present some daily,seasonally and yearly variation discipline;(2)In the forest,water can affect negative air ion level;(3)Daily variation of negative air ion concentration is significantly negatively correlated with air temperature and positively correlated with air relative humidity in forest recreation areas;Daily variation of negative air ion concentration is significantly multiplely correlated with air temperature and air relative humidity in forest recreation areas;Yearly variation of negative air ion concentration is irrelevant to air temperature and air relative humidity humidity in forest recreation areas;(4)The space distribution discipline of negative air ion concentration is following:waterfalls>rivers>forests> unpaved roads>cement roads.
