Analysis And Health Evaluation Of Public Welfare Forest Structure In Daheishan Forest Park Of Beipiao City

With the rapid development of the national economy and the improvement of people's living standards,the emphasis on the ecological environment has gradually increased.Therefore,the protection of forests,especially the protection and role of public welfare forests,has gradually emerged,so the construction of public welfare forests is gradually improving.This paper is aimed at the status quo of public welfare forests in Beipiao Daheishan Park in Liaoning Province and how to construct public welfare forests.The health evaluation method is used to improve the quality of public welfare forests to realize the sustainable management of public welfare forests.This study summarizes the natural and social generalization of the Daheishan Forest Park,analyzes the structure of the public welfare forests in the region,and uses the analytic hierarchy process to evaluate the health of the public welfare forests through the status quo of the public welfare forests in the region,and proposes the Daheishan Forest from the evaluation results.Suggestions for the management of park public welfare forests.1.Daheishan Forest Park has a public welfare forest area of 15875.0 hm2,accounting for 85.12% of the total forest area.The forest age structure in the area is more suitable,and the proportion below the near mature forest has reached 85%.The forest stands are mainly natural forests,with a proportion of 80.1%.The species are mainly Mongolian oak and Pinus tabulae,which are suitable for the local environment,with a proportion of 66.53%.The Daheishan public welfare forest management mainly focuses on water conservation,among which The main source of broad-leaved forest is water conservation forest,with the proportion reaching 60.32%.At present,the forest resources of the forest park in Dahei also have a single structure,fragile ecology and slow recovery.2.Based on the status quo of Daheshan Public Welfare Forest,four major health assessment indicators of forest tree productivity,forest community integrity,forest risk and soil condition were selected from 20 standard plots to evaluate the health status of public welfare forests in the region.The Great Black Mountain Forest Park public welfare forest is between sub-health and health,with an average health index of 0.562.3.According to the results of health assessment,we can choose appropriate tending measures,improve low-efficiency forests,speed up the main cutting,improve the fire prevention facilities,strengthen the prevention and control of pests and prevent pest invasion,and strengthen the invasion of aliens;In the management of forest land,it is suitable for the treatment of fertilization and litter to improve the management of public welfare forests in the Daheishan Forest Park.
