Study On Planning Of Beiluoxiao Forest Health Base In Hunan Province Based On Ecological Sensitivity Analysis

Following the fourteenth five-year plan and the 2035 long-term goal,the forest health industry has developed rapidly,and the forest health industry effectively seeks a balance between economic development and ecological construction,and promotes the upgrading of the forestry industry structure while paying attention to the health of the people..However,in the planning and construction of part of the Forest based health and wellness base,there is an understanding of the ecological priority principle,especially the lack of ecological sensitivity analysis to provide guidance for the planning and construction of the Forest based health and wellness base.As a result,the construction of the health care base cannot be well coordinated with the local ecological environment.This thesis takes Beiluoxiao National Forest Park in Pingjiang County,Yueyang City,Hunan Province as the research object,starting from an ecological perspective,and based on the theoretical research of forest health and ecological sensitivity evaluation,combined with field investigations to obtain basic data,and using the GIS platform to complete the ecological sensitivity evaluation of Hunan Beiluoxiao Forest Park.Combining the distribution of health resources in the forest park,and based on the results of ecologically sensitive zoning and evaluation analysis,guide the completion of the site selection of Hunan Beiluoxiao Forest based health and wellness base and the overall planning and special planning practice of the health care base.The main research results are as follows:(1)The relevant literature and theoretical basis of forest health and ecological sensitivity evaluation are sorted out,and the necessity and feasibility of ecological sensitivity evaluation to guide the planning of health and health bases are discussed from the theoretical level.(2)On the basis of data preprocessing,the Hunan Beiluoxiao Forest Park ecological sensitivity evaluation system was constructed.After screening and determining the evaluation indicators,the ecological sensitivity single-factor evaluation was completed;combined with the theoretical method of the combination weighting method,Calculate the corresponding weight value of each evaluation index;correspond the ecological sensitivity single factor evaluation result with the weight value of each index factor,and use the weighted overlay analysis function of the GIS platform spatial analysis to calculate the comprehensive ecological sensitivity evaluation result.(3)The calculation of Hunan Beiluoxiao Forest Park’s ecological sensitivity evaluation index weight adopts the combination weighting method combining the analytic hierarchy process and the coefficient of variation method to reasonably coordinate the subjective arbitrariness of the decision maker’s empirical judgment and the objective mechanical nature of the data itself.The 10 indicators are sorted in descending order of the weight value as follows:vegetation coverage 0.220>negative oxygen ion 0.161>canopy closure 0.138>land use type 0.111>vegetation type 0.084>water buffer zone 0.077>road buffer zone 0.066>elevation 0.0521>slope direction 0.0519>slope 0.039.(4)According to the ecological sensitivity level classification standard,the ecological sensitivity of Hunan Beiluoxiao Forest Park is divided into 5 levels.According to the analysis of the comprehensive evaluation results,it is found that the area of each sensitive level area accounts for the proportion of the total area ofHunan Beiluoxiao Forest Park:high The sensitive area accounted for 18.9%,the higher sensitive area accounted for 34.4%,the medium sensitive area accounted for 32.7%,the lower sensitive area accounted for 12.6%,and the low sensitive area accounted for 1.4%.(5)Based on the ecological sensitivity evaluation results of Hunan Beiluoxiao Forest Park,combined with the distribution of forest park health resources and forest health related policies,the Hunan Beiluoxiao Forest based health and wellness base was completed,and the evaluation was based on ecological sensitivity As a result,suggestions were made for the planning of the health care base.(6)Hunan Beiluoxiao Forest based health and wellness base puts forward a scientific and reasonable planning strategy in accordance with the principles of ecological priority,and completes the overall planning in terms of spatial structure and functional zoning.The functional zoning part will be Hunan Beiluoxiao Forest based health and wellness base.It is divided into four functional areas:forest health and recreational recreation area,forest health and sports recreation area,forest health science popularization experience area and forest health and natural rest area.And complete the special design of the health care base from four aspects:plant landscape planning,vertical planning,road system planning,and service facility planning.
