Health Assessment And Health Function Of Scenic And Recreational Forest For Different Forest Types In Xiamen Suburban Forest Park

With the development of forest tourism,people are increasingly eager to contact with nature.Scenic and Recreational forest as a special kind of forest, it plays important role in the forest tourist trade, the researcher increasingly pay attention to it. Based on the typical scenic and recreational forest of xiamen suburban forest park as the object of study, by ecology index, and Analytical Hierarchy Process(AHP)to assess level of the current health of forest sands, at the same time,using indicators of human comfort, air suspended particulate matter to study what it have healthy function, which is purpose to foundation of forest health management guidance,Suggestions and reference people’s recreational activities. The result indicates:1.Through investigating on scenic and recreational forest community, using methods of the typical sands investigation to investigating the typical scenic and recreational forest,then calculating the diversity index, it is concluded that the species diversity index of tree layer and shrub layer, the results also shows that different layer of shrubbery species composition and quantity are different, and there are differences but not significant; the species richness is not high(the tree layer up to 7), the overall community forest structure is simple.2.Establishing the health assessment system by the AHP for scenic and recreational forest of Txiamen suburban forest park. According to the results of the assessment:60% of them are above health condition, the sub-health sites accounting for 30% of the total and unhealthy sites accounting for 10% of the total, indicated that scenic and recreational forest of xiamen suburban forest park have a healthy condition, but studies shows that different index of major weights have an important impact on the outcome.3.Selecting the typical scenic and recreational forest as the research object, taking human comfort, air suspended particulate matter for health function factors, analyzing diurnal variation of scenic and secreational forest’s health functions in the winter, and taking the parking area as a reference, the research shows that:(1) human comfort of four different recreation lands in winter shows that morning and evening higher, midday lower trend. (2) excepting broad-leaved forest,diurnal variation of comfortable living in other recreation forests are not comfortable.its recommended that people had better not to go to scenic and recreational forest in suburban forest park, but if want to the recreation, you had better to choose go it between 11:00 and 15:00. (3) it can be seen from the air suspended particles matter variation:diurnal variation of air suspended particulate matter in four kinds of recreation lands in winter like an approximate U-shaped,and morning and evening higher, lower midday. (4) the TSP, PM10, PM2.5,PM1.0 and relative humidity have significant positive correlation, but with temperature have significant negative correlation.4.Analyzing that correlation between health functions and structural characteristics of forest,it shows that between average of wind velocity and average of DBH have a significant negative correlation, indicating that the larger DBH in Forest stands,the more wind will be resisted. Average of DBH, average of the tree height, canopy density with three different particle diameters have a negatively correlated, but not significant, it also shows that the bigger DBH,the higher of tree height,canopy density, the stand volume,which are more efficient in reduces the atmospheric particulate matter...
