The Impact Of The Natural Forest Protection Project On The Forest Stock Volume Of No. 27 Linban In Shuangfeng Forest District

The Tianbao Project is an ecological protection project at the present stage of our country.It has made important contributions to the prosperity and sustainable development of China’s forestry,and is a major measure for the benefit of future generations.In today’s dramatic global climate change,in-depth study of the impact of natural forest protection projects on the volume of forest reserves,determine its changing rules and influencing factors are urgent issues to be solved.Taking the No.27Lin Ban in Shuangfeng Forestry Bureau as an example,based on the work data of Shuangfeng Forestry Bureau for 15 years,this paper takes five years as a time unit,in-depth understanding of the total amount of forest stocks,natural forest stocks,artificial forest stock volume and forest tree biomass factors,and major environmental factors affecting their changes after the implementation of the natural forest protection project in Shuangfeng Forestry Bureau.The main conclusions of this paper are as follows:(1)Since the implementation of the Tianbao Project,the forest resources of No.27 Linban in Shuangfeng Forestry Bureau have been significantly improved.In the past 15 years,a cumulative increase of 4483 m~3 of forest reserves was recorded.In addition,the natural forest reserves have been more significantly increased with a cumulative increase of 6092 m~3.This is mainly due to the fact that since the implementation of the Tianbao Project,Shuangfeng Forestry Bureau has been vigorously developing the protection of natural forest resources,increasing the proportion of natural forests in the region,and at the same time reducing the relative proportion of planted forests.(2)During the 15 years of the development of the natural forest protection project,the canopy density of the 27 forest trees in the Shuangfeng Forestry Bureau area,the net growth rate of the forest trees,the average tree height of the trees,and the average DBH of the trees have all been significantly improved.(3)For No.27 Linban forest reserves in the Shuangfeng Forestry Bureau,the average annual temperature,the average annual minimum temperature,and the average annual precipitation have a significant effect on the increase.At the same time,the redundancy analysis shows that the average annual precipitation is the best environmental interpretation factor for all forest volume and tree biomass factors,with the interpretation rate of 69.4%;the average annual temperature is the second,and the interpretation rate is 26.3%.
