Investigation And Evaluation On Forest Health Care Function

Suburban forests are important places for people to travel,rest and entertain,and are also the main places for the city and surrounding residents to carry out forest recreation activities.Scientific research and assessment of suburban forest health functions.Construct a evaluation system for the rehabilitation of suburban forests.Divide the type of suburban forest health conservation.It is of great significance to guide the development of regional forest health industry.To carry out the construction and quality evaluation of the suburban forest health care base.It is of practical guiding significance for people to carry out forest recreation activities reasonably.It is also a positive measure to implement ecological civilization construction and accelerate the transformation and upgrading of the forestry industry.This study takes the Yinchuan Botanical Garden as an example.Research and evaluation of suburban forest health,this study through the literature research method,data monitoring statistical analysis.The study identified factors related to the forest health function.It is confirmed that the forest environment has the value of providing forest health.It is necessary to clarify the research on the function of forest recreation in suburban forests.The research and evaluation of the suburban forest health function are mainly carried out from the aspects of environmental quality and natural resources.Analytic hierarchy process(AHP)and expert scoring are used.Construct a model for evaluation system of forest health care function in suburbs of Ningxia.Divide the functional level of forest health in the suburbs of Ningxia.According to the model and the standard obtained,the forest health function of Yinchuan Botanical Garden was evaluated.The main findings are as follows:(1)Identify factors related to forest health functions:forest cover,negative ion content,temperature,humidity,PM2.5,biodiversity,oxygen content,carbon dioxide content,noise conditions,purification of the atmosphere,environmental radiation,forest area,surface water quality,airborne bacteria content and green rate and other indicators.The above indicators can be summarized as environmental quality indicators and natural resource indicators.(2)Evaluation of the value of forest health function in Yinchuan Botanical Garden:carbon fixation and oxygen release function(78829.50 yuan/year)>price adjustment microclimate function(54,469.49 yuan/year)>biodiversity protection function(34,124.42 yuan/year)>provide negative ion function(13662.63)Yuan/year)>Purify the atmospheric function(5471.76 yuan/year),the total functional value reached 186,557.80 yuan/year.(3)A comparative analysis of the health care function of the forest environment quality of Yinchuan Suburban Botanical Garden and Phoenix Park in Jinfeng District of Yinchuan City is shown.The air negative oxygen ion content,environmental radiation,temperature,humidity,PM2.5 content and acoustic environment index conditions of Yinchuan Botanical Garden are better than those of Yinchuan Jinfeng District Phoenix Park.(4)Using the survey scoring method and AHP analytic hierarchy process to construct a suburban forest health maintenance function evaluation system model.The evaluation system consists of two criteria layers,six element layers,and a total of 21 indicator layers.Sorting weights of 21 indicator factors:forest coverage(0.1267)>negative ion content(0.1244)>landscape attractiveness(0.0922)>climate comfort(0.0855)>service facility(0.0715)>PM2.5(0.0601)>biodiversity(0.0558)>Science and Education Value(0.0504)>Carbon-releasing and oxygen release(0.0462)>Noise condition(0.0456)>Purification of the atmosphere(0.0422)>Intemal transportation system(0.0300)>Environmental radiation(0.0289)>Location(0.0281)>Forest area(0.0242)>Surface water quality(0.0197)>Air bacteria content(0.0167)>External transportation system(0.0165)>Green vision rate(0.0151)>Passenger source condition(0.0113)>Parking lot(0.0091).(5)It is based on the evaluation model of suburban forest health maintenance function.The evaluation score of the forest health care function of Yinchuan Botanical Garden was 3.8535 points.It belongs to Class I in the classification of forest health maintenance function grades in the suburbs of Ningxia.Suitable for forest recreation activities.
